World History, PBL, and 3D Archaeology

Reading about archaeology and museums and ancient civilizations can be a lot like reading about anything else at school – some kids might find it moderately interesting, while others probably would not. But what if students could play the role of archaeologists and museum curators, researching and creating their own museum exhibits using the very latest in super-cool modern technology?

I teach a World History survey course to 8th graders in Fredericksburg, Virginia. The scope of the content covers time from the Paleolithic Era to 1500 CE, and in the first few weeks of school, students are introduced as much to the study of history as to the content. In a virtual meeting with an archaeologist, my co-teacher and I got the idea for a Project-Based Learning (PBL) experience, culminating with a museum exhibit, complete with 3d-printed artifacts and augmented reality software, to showcase their learning to their parents. Below is the outline of the PBL.

The Entry Events:

img_3330I. Meeting with a Professional:

During the first month of school, students met (via Google Hangouts) a real archaeologist, Sarah Miller, and were introduced to the field, learning how the science of archaeology helps us understand the past. Miller told us about her work and shared how new advancements in technology improve knowledge of the past. (The Standard of Learning related to this lesson states, “Students will be able to explain how archaeological discoveries are changing present-day knowledge of early peoples.”) She discussed how archaeologists can get a replica of artifacts as 3d printables,
and sent us this picture of a Sumerian ziggurat. She said scans of the ziggurat and thousands of other ancient artifacts were available for free in museum libraries on the img_7400internet. Anyone can download them and print the artifacts in 3d (though of course many would be miniature versions of the originals, since few people have pyramid-sized 3d printers.)

II. Teacher’s Personal Experience with a Museum:

Last summer, I visited the Louvre and I showed students some pictures, sharing with them how meaningful it was for me to see artifacts from civilizations I have taught about for years (civilizations they are about to study — Mesopotamia). I then introduced the Museum project: Students would create a museum exhibit on a civilization or topic and have the opportunity to choose an artifact to print using our school’s 3d printer.

III. School Vision: Involving stakeholders

We are a school that needs our parents to feel connected, so I invited Mrs. Frazier, our principal, to talk to students about how much we want their parents to feel welcome at our school. She expressed that students can help by inviting their own parents to see their museum exhibit on Parent Teacher Conference Night.

THE MAGIC: PROJECT BASED LEARNING

Phase 1: Introducing the topic

img_3817I introduced the task and driving question for students, “How do we as museum staff create an exhibit to show the achievements of our topic?” Topics included empires of Mesopotamia, kingdoms of Egypt, and empires and religions of classical India. Our Instructional Technology Resource Teacher (ITRT) and I used the book Learning on Display to help us organize the process and create rubrics for assessment. We began with a Gallery Walk and students reflected on the following:

  • What is a Museum?
  • Why do we have museums?
  • What makes museums engaging for 8th graders?

Phase 2: Research

img_3853Students completed a research guide to learn more details about the society they were studying and determine what made their topic historically significant.

The teachers created questions directing students to find information aligned with the Virginia Standards of Learning (what students are supposed to be learning).

Phase 3: Exhibit Planning


img_3867Students planned their exhibit, and considered these questions:

  • How will we show what is important to remember about our topic?
  • How will we get visitors to experience our story?
  • What will our completed exhibit look like?
  • Will our exhibit work?

img_3865In groups, students showed their plan on large paper so that they could receive feedback from fellow students to inform their revisions.

After the plans were posted, students completed a gallery walk, viewing their peers’ plans to offer feedback that should be specific, helpful and kind. Students used post-it notes, and based on the protocol I learned at Buck Institute, they were given sentence starters: I like to commend an idea, I wonder to ask clarifying questions, and I have to offer a suggestion.

Upon being asked to reflect on the gallery walk, one student said, “criticism is not all bad. . .this is helpful!”

img_3873One group said, “we didn’t get a lot of helpful feedback” so they asked if they could present their plan to the whole class. I thought this was so powerful for students to put themselves “out there” for help.

After receiving feedback, students revised their plans, and were ready to put it all together.

Phase 4: Writing a Label Copy

img_3837Before students were able to print their artifact and set up their exhibit, the label copies were written to help their visitors understand the key points of their display, including the relevance of the artifact. The idea of creating the label copy before the creation of the exhibit is that if they waited until after the exhibit was done, they would be too excited to calm down and “write,” BUT it was wonderful to see them edit several times before the final copy was finished.

Phase 5: Constructing the Exhibit


This was the most exciting part for the students as they saw their research, plans, revision and ideas come to fruition.

Not all students chose to print a 3d artifact; a few students used the program Aurasma, making the exhibits interactive.

Here are a few comments from the students:

img_3959PBL was very good at teaching students to research on a focus and create project that not only teaches the student but others as well. The 3-D printer is a great way to create an artifact since most students can’t go around an archaeological dig. The 3-D printer is also good to create an artifact if a student’s focus was not able to have any historical artifacts. We didn’t really learn about archaeology in the PBL, but Archaeology was taught throughout depending on each focus project. Archaeology and artifacts helped us learn about what influenced the people of the time and what their life was like. – Paulo Pulido

img_3956I liked using a 3d printer because it creates a visual. I learned that archaeology is very time consuming and you have to be patient.

I think using a 3D printer for an artifact is a great idea. It makes the project more hands on.

img_3965On the last day of the project, as students were busily putting their exhibits up, some leaders from the school board – including Dr. Scott Baker, Superintendent and Mr. Keith Wolfe, Executive Director of Secondary Education and Leadership – observed the students preparing their exhibits. They were so intrigued by what we were doing they came back the next night for Parent-Teacher Conference night to see the students showcase their projects. Most of our parents came to interact with their students as they demonstrated their learning of their topic in history as well as the authentic tasks of creating a museum exhibit using real-life tools of the trade in archaeology.  

img_3964As an 8th-grade teacher, I may see 4-5 parents a couple times a year for “Conference Nights,” but more than 40 families came to interact with their children as students shared their learning.

This experience was an opportunity for students to see the relevance of history in a 21st-century setting, where they combined modern technology with the old-fashioned skills of inquiry and collaboration.

Painting an Olive Jar Neck Sherd from the Luna Site in Pensacola, FL

Last month, I discussed some useful tips on how to paint 3D printed plastic objects. Today, I will walk you through the painting process using an olive jar neck sherd from the Luna site. The sherd was one of the defining artifacts that helped UWF archaeologists recognize and establish the significance of the site. Below is my step-by-step guide on how to paint this specific artifact using the equipment and tips I outlined in my previous post.

  1. painting-stationHere is my painting station, equipped with the colors I use for this artifact (minus two that I added in), paint brushes, paper towels, my “palette,” and a water cup. 
  2. I start by adding a layer of unbleached titanium over the whole object.first-layer-ubt-mariana
  3. Then, I mix some paints to create the reddish color of the entire vessel. I use red and yellow to create a salmon color and add bits of Unbleached Titanium and Raw Sienna. I use the dabbing technique to create texture.

    1. Here is a close-up of the texture.
      second-layer-detail-mariana
    2. Here is the entire second layer.
      second-layer-whole-mariana
  4. colors-used-for-gray
    Colors used for gray.

    I mix the colors I use for the gray sides of the artifact. I obviously do this by mixing white and gray and then paint one layer on the sides. For a second layer of gray, I add a little bit of Raw Umber to the mix, which makes it slightly more brown. When I layer it on top of the light gray color, it creates depth and texture. There is also a line of gray at the bottom of the artifact.

  5. I do something similar to the entire object now. I add a little bit of grays and browns over the entire object to match the various tones and colors the artifact has in real life. I do this using a mix of dabbing and dry brush techniques and I try to be gentle and light about applying this layer.
  6. The final touch is to add a black detail towards the bottom corner of the concave side.

  7. This is the final product:

The final product is definitely not perfect, but it will do! Painted models, such as the olive jar neck sherd, can be implemented in educational demonstrations in classrooms, out in the field, in museums, or anywhere where archaeologists are able to interact with the public. I really hope that you enjoyed these blog posts about painting plastic artifacts and found some useful information. As always, feel free to respond with any questions or feedback.

Happy painting!

Bringing Archaeology and 3D Modeling to the K-12 Classroom

Many archeologists, as part of their public outreach efforts, see the recent movement to bring science and math based curriculum into classrooms as an opportunity to introduce both teachers and students to archaeology and anthropology. This trend has also caused schools and programs to reach out to archaeologists and other scientists to present to their students. However you end up standing in front of thirty 5th graders, there are some things that will help you achieve your goals and survive to see another invitation extended to you.

I would argue that archaeology is uniquely suited to classroom presentations in that it covers every subject being taught in today’s schools, especially when 3D modeling is included, and is an inherently hands on and accessible science. In order build an easy to use guide for people interested in bringing 3D modeling and archaeology to public education I have drawn on my knowledge of the public education standards and how to best cooperate with public school teachers, gained by five years experience in a classroom. Though I will focus mostly on archaeological modeling and K-12 education in this post, all of the material covered here is applicable to all fields of anthropology, all subfields of archaeology, and really any field of science.

Getting into the classroom

The two biggest things to remember when presenting in a kindergarten through 12th grade education setting is time and flexibility. Time is everything to a teacher, and even more important to the students. Frustrations about time are not necessarily exclusive to the time you are taking out of their day by presenting. Sometimes it is the time of day you want to come into the class, and sometimes it is the time of year. This is where flexibility comes in. Here are my quick and easy tips to getting a teacher to say yes, and to have them ask you back:

  1. Contact schools you work with and get a school calendar, or join their Facebook page. If you know what is going on at school a teacher will not turn you down because you asked to come and present on field day. 
  2. Know or ask what topic/subject they are covering and explicitly tell the teacher how the material you are presenting matches that. My other suggestion to this is do not concentrate only on science. See the next section for more details on this. 
  3. Bring ALL necessary supplies (including pencils and paper) and make sure to communicate this with the teacher. Also, if you will be using computers, arrive early and make sure everything is in order for the kids to log on.

Standards

All topics taught by a teacher must meet what they call a standard. These standards can include things like teaching a kindergartener that a book has a front cover and a back cover (standard “LAFS.K.RI.2.5”). Before you freak out I’m not proposing that anyone learn the standards, though they are available for your reading pleasure on every state’s education website. Here are the Florida standards for language arts and math by grade level.

The chart below connects the four main subjects to 3D modeling and printing in archaeology. The great thing about many topics covered within each subject is that they can be taught at almost every grade level, with varying degrees of difficulty of course. Elementary schools, for example, may only have the students classify according to shape, size, and color whereas middle schoolers are capable of predicting the use of an object and classifying based on those observations. Seeing these parallels will save you some time in writing lessons and will increase the variety of grade levels you can present in.

To help clarify, I will expand upon one topic within each subject and choose a grade level to give a better perspective of how they connect to classroom instruction.

Math: Scale and Ratio

In Florida, most 6th grade students are beginning to learn how to work with ratios and scale modeling. A possible lesson connection could be scaling a building within modeling software so that it could be displayed and explored in a museum by smaller kids. This is a hands-on math intense topic that helps others and has real world applications.

Science: Classification

Elementary students begin to classify objects very early on, by shape and size, as early as kindergarten. Using 3D printed lithic points and pottery students could work on their classifying skills while also handling what would otherwise be fragile artifacts.

History: Understanding Context

Holding an object only seen in pictures before can often be revolutionary. Changing a person’s perspective and understanding of an item. High Schoolers begin writing research papers early on in their freshmen year, and often write about things they have only seen in books. Physically touching a cannonball that shattered on a tree, like the one printed by UWF students Janene Johnston and Mariana Zechini, can add context to the tree, the cannon ball, and the person who surely escaped death.

Language Arts: Writing

Amazingly, this is often forgotten by archaeologists and yet comprises a large percentage of what we do. Academic writing and writing an opposing critique are skills they will need as they move into college, something we as archaeologists and scientist are painfully aware of. Archaeologist have a unique relationship with journaling and note taking, a skill that many take for granted.

 

By providing some general examples and simple tips, I have given those that desire to bring 3D modeling into a classroom some tools to access the world of education standards. Because this is only a starting point, if you are an archaeologist hoping to do some public outreach or a teacher looking to give some of your standards a new spin with real world applications, please share if you have ideas of your own.

Painting the Past: Using Paint to Bring Plastic Artifacts to Life

Scanning and printing in 3D has many applications to the world of archaeology and one of the greatest is its utility in public archaeology demonstrations. However, because plastic models are usually printed in one solid color and are mostly hollow to speed up the printing process, the result does not look or feel much like the original artifact beyond its general shape. To remedy one of these disadvantages, we paint 3D printed models at the University of West Florida. We do this to make the artifact look more realistic and to create a more intimate relationship between the viewer and the artifact. By painting plastic artifacts, we allow the viewer to better understand the object and how it looked during use, after excavation, or following conservation.

After I started painting models at the Virtual Curation Laboratory at Virginia Commonwealth University, under Dr. Bernard Means, I began 3D printing and painting for Dr. Kristina Killgrove and the Archaeology Institute at the University of West Florida. Along with some other graduate students, we have painted various types of artifacts from different sites, including hominin and animal bone. Below is a list of equipment needed for painting and some tips I have found useful throughout my experience. Additionally, I have included a step-by-step guide to painting, using an olive jar neck sherd from the Luna site.

Equipment

  1. A variety of brushes. Ideally, you want as many different types of brushes as possible so that you can re-create as many different patterns as possible. I suggest using any variety of skinny, round tip brushes, flat tip brushes, fan brushes, and angled tip brushes in small and large sizes. You will need the skinny, small brushes for detail and the larger flat tip brushes for larger surface areas. I suggest buying a variety pack of 20-30 brushes on Amazon and experimenting with those.
  2. Acrylic paint. My favorite brand to use is Liquitex Basics. If you are not sure what colors you will need, I suggest buying either the 24- or 48-pack of acrylic paint and seeing which colors you use the most. Or you can buy the 4oz tubes of the colors I have found I use the most (I have never needed the hot pink to paint a plastic model):
    1. Yellow Oxide, Titanium White, Burnt Sienna, Ivory Black, Red Oxide, Burnt Umber, Raw Umber, Raw Sienna, and Unbleached Titanium
  3. Paper plates and cups (or whatever you have at your disposal) for palettes and water cups. I usually use a paper plate as my palette and reuse it as much as possible. I do the same with a water cup and paper towels.
  4. Fixative (optional). I have never had a problem with paint wearing off a plastic artifact. However, if you know the object will be handled a lot, it might be useful to buy a can of spray fixative, which sets the paint and prevents it from rubbing off. Alternatively, hairspray can work as a cheap fixative if you’re in a bind.
  5. An open mind! I love painting plastic models because it combines my love of art and my love of the past. I was an art student for one semester, although I was planning to major in photography, not painting. This experience has been useful but is absolutely not necessary. I never thought of myself as a painter (and I still don’t) but keeping an open mind allows me to be more confident in my painting. So do not be afraid to mess up or try new techniques! The worst that can happen is that you have to paint over it and try again.

Tips & Techniques

Below are some tips and techniques that I have found useful through my experience. These are only suggestions and it would be a good idea to experiment and see what works best for you!

  • I like to paint each object with one coat of Unbleached Titanium. This is an cream color that works as an excellent base coat by covering up the original plastic color and allows the following coats to be richer in color. It is not totally necessary, but if I accidentally miss a spot while painting, this base coat provides a more natural color (depending on the object, of course) rather than solid black, white, or gray, which are usually the colors that I print in.
  • Use different painting techniques! For example, I prefer to dabble rather than paint one even coat all over the object. Dabbling provides texture, which is absolutely necessary when representing artifacts. For example, dabbling helps to create the porous texture that most ceramics have and also adds an extra dimension to the object. Other techniques include washing, dry brushing, and stippling. For more info on painting techniques, check out this blog.
  • Let each coat of paint dry, especially the first coat! Layering the colors is much easier if each layer is dry. This prevents two or more paint colors from mixing and allows you to keep the texture of the object exactly how you want it. Plus, it makes for a less messy painting experience…or, at least, it helps.
  • Do not be afraid to mix paint to get the exact color you need. Sometimes the exact color we need to use does not come straight from the tube. For example, to get the perfect brown, I sometimes have to mix lighter shades in with darker shades, or add red, yellow, black, or white to get the tones right. Do not be afraid to experiment!
  • Use one color at a time. What I mean is, focus on one or two colors on the object and paint those all at once. This makes it easier for you to maintain the same colors throughout the object, especially if you had to make a custom color. This way, you don’t need to remember the exact ratios and colors.
  • Always use a clean brush whether it’s brand new or just washed. Accidentally mixing your last color with your newest color can mess up your work.
  • If you are painting ceramics that have a glaze over the artifact, I suggest using glue as the final step to create a shiny surface that mimics the glaze.
  • Do not be afraid to mess up! The best thing about painting is you can always paint over anything you do not like. Painting is very forgiving because no matter how many times you feel you may have messed up, you can always re-paint!

These are some ceramics from sites along Garcon Point in Pensacola. The artifacts on the right are real and the ones on the left are painted. These were painted by graduate students Jane Holmstrom, Katy Patterson, and myself.

Depending on the artifact, painting can take a few hours. Overall, 3D scanning and printing can be a tedious process that is only lengthened (but greatly enhanced!) by painting. Scanning an artifact can take anywhere from 30 minutes to an hour and a half. Printing is the longest step that could take up to several hours, depending on the size and complexity of the model. The olive jar neck sherd, that I will walk you through next month, took approximately an hour to scan, an hour to print, and 30 minutes to paint. While these processes can be time consuming, they greatly enhance the public’s experience with archaeology!

I hope this painting tutorial helped give you some tips, tricks, and ideas for painting plastic artifacts in your very own lab! I would love to know what you think, so please feel free to leave any questions or comments!

Using Tinkercad And Other Modeling Systems to Contextualize Structures in The Classroom

In last week’s post, I discussed a watermill model that I created as part of my thesis research, this week I will discuss the program I used. Because I am a graduate student and new to modeling, I needed a program that was free and relatively easy for a novice to navigate. The program itself had to allow me to create the model from scratch. This was important because unlike photogrammetry, I wanted to make my model using measurements taken in the field and reconstruct the mill rather than just render it as it stood today.

Once I began working with Tinkercad, the website that I will review today, I realized its educational possibilities. Tinkercad is a free, browser-based CAD program, and is in no way the only option out there. As a former teacher, this program could easily be incorporated into classroom lessons. In my experience creating my watermill model, this is an exceptionally user-friendly, and free site for creating a free-form model and also possesses numerous applications in and out of the classroom.

Tinkercad is part of a family of free apps available from Autodesk 123D, I have not experimented with the other apps, each of them have different applications. There is an app for iPads as well as one that can generate 3D models from photos, much like PhotoScan, though I think PhotoScan is a more intense and professional process, an opinion based on limited experience. Most of the programs and sites I found, which are listed at the end of this post, were not suitable for my project due to requirement of downloading software or that only a short trial membership was available before requiring payment.

tinkercad

A free account with Tinkercad lets you create designs and save them under different projects, allowing for generational designs; it also allows you to create several types of downloadable files of your model that can been uploaded to other sites such as Sketchfab. The resulting file can also be used to print your model either with a personal 3D printer or by a company of your choosing. There are two formats to create designs with, normal or Beta. Beta differentiates mostly in the user interface, allowing the use of keyboard shortcuts, as well as the ability to collaborate with others.

Once an account is set up, the user is free to create projects and then save them to be accessed later. Once the project is created a work plane is displayed, at this point it is imperative that the scale you wish to use is set. In the bottom, right hand corner an edit grid option is displayed, inches and millimeters are your two options. For inches, 39.37 x 39.37 is the largest grid possible and for millimeters a 1000 x1000 grid is the limit. If a larger grid is necessary, this program is not a good option. The grid is easy to use and when scaling an object, the rulers that measure the item as you move it are invaluable.

Though you can create your own objects to use in your model, the provided geometric shapes and the community created objects are very versatile. One of the best features is the ability to use an object as a “hole”, for an example of this I used a cylinder and a sphere to create a ditch in the top of the cylinder. The hole is completed when you group the two objects together.

Shapes are also very easily manipulated. The example I’ve shown here is a pyramid altered into a thin section to make a trowel. Going into the program and manipulating the shapes is the best way to learn to navigate the program. One important feature is the Fit to View Selection this focuses in on the selected shape and helps when working with them. Of course, you can always create your own shape and even import shapes from your computer or other sites. Given a little bit of time and practice manipulating the shapes and holes, custom shapes and objects are easily rendered for specific items.

This program is an exceptional option for use in public education settings. Some possibilities for this program in the classroom I can see are:

  • Having students explore symbols and how to create them
  • Using static objects such as cylinders or boxes and inventing a useful tool
  • Using scale to model an existing item or building
  • Designing an artifact from the past or one of the future

Without creating a full tutorial on how to use this site, I hope I have provided a starting point for anyone interested in modeling. Tinkercad provides a wide assortment of tools and an easy to navigate “sandbox” with the grid system to allow for a large degree of control over your design. In the classroom, students can create their own personal accounts because the program allows for collaboration between users; there is not a download requirement (most schools require permission to download programs, so you can skip the IT department).

This site is most certainly not the only one available to aspiring modelers. Here is a list of others I have found and explored:
