Modular Origami Paper Puzzles

Paper is such a great medium. You can find it almost anywhere. With a couple of quick folds you can transform it from a fragile flat piece into a strong 3D object. Most people are familiar with origami, the art of folding paper – if not, learn more here with a Scholastic Origami Math lesson. But fewer people are familiar with modular origami, which is a technique that involves creating folded pieces that can be connected together to create larger 3D models. For example, you can fold a piece of paper like this to create one module:

and combine 6 modules to create a cube

or combine 12 modules to create an octahedron

or 30 modules to create an icosahedron.

Grab some thin paper and follow this Math Craft tutorial to create your own.

Popsicle Stick Mathematical Sculptures

IMAG4270You know what we love to build things with? Everyday objects, like popsicle sticks! Inexpensive, light-weight, and versatile, these are an easy way to construct a variety of things with tape or glue and can easily be decorated with marker, paper, or string. From bridges to buildings, creatures to words, you can really build almost anything with them. We like to get geeky and these materials and build mathematical sculptures. These are not only a great hands-on mathematical learning tool for exploring abstract concepts (physically scaffolding from 2D shapes to 3D forms), but can also become decorative sculptural lighting elements. Though you can make almost any angled shape or form with popsicle sticks, we recommend starting with building a cube first then working on building up to an icosahedron, which has 20 faces (each face is an equilateral triangle), 30 edges, and 12 vertices (5 edges meet at each vertex).

Gather Materials:

  • (at least) 60 popsicle sticks
  • hot glue gun
  • hot glue sticks
  • tape
  • optional decorations, paper, transparency film, markers, buttons, string, etc.
  • battery operated tea light

Make It:

  • Follow this great tutorial to build an icosahedron.

Design Experiment Considerations:

  • Cover each face with different material and experiment with shadow play.
  • Hypothesize how much strong it would take to wrap the entire sculpture.

3D Digitization: Creating Virtual Copies of 3D Objects

Though academic institutions and museums are using costly 3D scanning equipment for their photogrammetry and 3D digitization efforts (see previous post), there are several free 3D scanning apps that allow users to capture photos taken 360 degrees around and object and easily generate virtual copies and 3D models on their own.

Autodesk 123d Catch
Autodesk 123d Catch is a free app for smartphones and tablets that allows you to create 3D scans of virtually any object. With built in guidance, it helps you set up proper lighting and provides advice for how to ensure 360 degree capture of the object. Once the object has been captured, you can upload to the Autodesk 123d cloud to share or download the free mesh-editing software to your computer for further editing and refinement of your 3D virtual model. The resulting file can be embedded into a website for virtual exploration or can be sent directly to a 3D printer.

Classroom integration example of Autodesk 123d Catch. Create a 3D scan capture of a 3D object found during an outdoor inquiry. *Bonus extension: upload the 3D model with an observation to iNaturalist and become a citizen scientist who shares with the global community.

Autodesk Recap
Similarly, Autodesk Recap allows you to capture 3D scans of an object, but has the added ability to leverage video as well. This “point cloud software” allows users to easily plan, measure, and visualize with advanced measurement as they can capture 3D objects and geographic sites, such as architectural layouts. Simply download the free software to a PC or Mac computer and upload digital photos or digital video files.

Classroom integration example of Autodesk Recap. Attach a digital camera (SLR, Smartphone, or GoPro) to a remote controlled helicopter drone to create a scan capture of your school campus and convert the capture into augmented reality.

3D Digitization: Exploring Virtual 3D Models

Huge paradigm shifts in museum culture are underway as a variety of institutions are engaging in 3D digitization to democratize their collections through the digitization of priceless artifacts and bringing access to the masses (Milroy & Rozefelds, 2015). Scientists in the fields of anthropology and paleontology have been using photogrammetry techniques to capture and record measurements of physical objects, but technological advancements now enable high quality digital scanning with specialized hardware, such as the Makerbot Digitizer (costs approximately $800) and the NextEngine 3D scanner (costs approximately $3,000).

Once the files are converted to virtual 3D models, they are made available on a variety of websites where you can access the files to download (as .stl formatted files) or explore within interactive 3D viewers.  This allows you to not only have access to the digital file (to print a physical copy of on your own) but it allows you to virtually interact with the 3d model on your own computer screen. Imagine being able to explore priceless artifacts that are typically hidden behind glass enclosures at a museum on the other side of the world or explore fossilized remains of ancient creatures found during a research excavation.

Smithsonian X 3D
Smithsonian X 3D is a 3D model database allows anyone with an Internet connection access to Smithsonian’s most renowned artifacts. You can explore a variety of virtual models by rotating the items, isolating different components of them, measuring them with built-in tools and creating specific views that can be shared over social media or embedded on a website or blog post just like a video. Additionally you can explore “tours” of select artifact collections and archaeological sites that are complete with 3D models, expert-written text, and additional resources.

Classroom integration example of Smithsonian X 3D. Take your students on a virtual tour of Cerro Ballena, Chile to learn more about whales ancestors by exploring Balaenopteridae fossils.

Morphosource
Duke University’s Morphosource is an image-sharing resource designed to allow users to upload, search, and browse high quality 3d models. is an online database of 3D models. Using the Creative Commons model, Morphosource encourages citizen scientist and the democratization of access to artifacts. As such, a variety of academic institutions and natural history musems are using Morphosource to facilitate collaboration, consolidate repository holdings, and provide access to the public.

Classroom integration example of Morphosource. Explore patterns in human evolution by comparing and contrasting virtual models of skeletal remains.

Digimorph
The University of Texas at Austin’s Digimorph is a lab that creates and shares 2D and 3D visualizations of the internal and external structure of living and extinct vertebrates, and a growing number of ‘invertebrates.’ Users can search a variety of specimens and explore virtual models and animations that detail the morphology of specimens in unique multimodal ways. With partnerships from a variety of academic institutions and paleontologists, Digimorph provides informative research publications with each specimen to deepen the potential learning.

Classroom integration example of Digimorph. Explore x-ray CT scans of various horned lizards and attempt to hypothesize reconstructions of what their ancestors may have looked like.

NASA 3D Models
Among the variety of data sets related to space exploration, NASA 3D Models contains a variety of 3D digitiazations of spacecraft, topographical maps, and plantary objects. Additionally, they have compiled several visualizations that allow users to explore landforms.

Classroom integration example of NASA 3D Models. Explore the impact that volcanic lava flows has on the near and far side of the moon’s surface.

MAKE things three-dimensional (3D)

The term “3D” gets spoken of a lot lately, especially “3D printing.” Though the term seems commonplace, sometimes we forget why 3D things are so cool and interesting. By turning something from flat 2D (two-dimensions) into a fully functioning 3D experience, we are not only engaging more senses (tactile touch) we are creating objects that have prescence from 360 degrees of viewing.

In order to expand this conceptual understanding of 3D printing, we challenge you to flip the term and consider what it truly means to “print in 3D.” Printing in 3D can be done with or without technology, as many mixed media artists will attest to the fact the amplifying their use of tactile textures is a favorite way to add the third dimension to their artworks.

To do this, we begin with hot glue…one of our favorite tools! Not only can hot glue be used to attach objects together or fix broken things, it is an amazing starting point for understanding 3D printing. After all a 3D printer is essentially a hot glue gun on wheels that is controlled by a computer.

Printing in 3D with Hot Glue Molds

Using a flexible silicone mold (i.e. Small ice cube trays and/or chocolate candy molds bought at grocery store for about $2 each, various shapes: hearts, stars, shells, mustaches, leaves, etc.) you can fill in with hot glue and small craft findings (sequins, glitter, etc.) to create your own 3D objects. Experiment with adding small amounts of paint or food coloring to change the color and texture of the hot glue. These objects can be displayed on shelves or turned into pendants and key chains by attaching yarn or cords. See more details in this tutorial (coming soon).

Drawing in 3D with Hot Glue

Using parchment paper (baking paper bought for a couple of dollars at grocery store) you can create 3D doodles and unique 3D objects. Experiment with drawing directly onto the parchment paper and see what happens when hot glue is added. Does the drawing transfer? Experiment with adding craft findings to the hot glue as you draw. Does the hot glue drawing have the strength to stand up on its own as a sculptural object? What can you do with these 3D hot glue creations? Use the dried creation as a printmaking stamp (cover with paint and press down on thick paper to make a print) or embossing tool (place paper over the creation and rub with crayon to create colorful textures). Attach yarn or string and turn it into a sun catcher for your window or wear it as a necklace, ring, or bracelet. See more details in this tutorial (coming soon).

Computer Modeling in 3D with Free Software

Using Autodesk 123D Design (free download for Mac, iPad, and Windows) or TinkerCAD (free web-based app used directly in Internet browser) you can create your own unique 3D models. The completed 3D models can be exported as “.STL” files and sent to a 3D printer and printed into a physical object. Don’t have a 3D printer of your own? Upload your file to www.shapeways.com and have them print it for you (costs vary based on the size of your model, which material you want it printed in, and how soon you want them to mail it to your home). Don’t want to wait for snail mail…search for a 3D printing service near your home on www.3Dhubs.com (enter in your zip code and a list of local 3D printing services are provided, rates vary). View our resources page for more related information.

Converting flat 2D files to 3D printable files

Ever wonder if there was a way to 3D print a flat clipart image? Well, there is. Thanks to the extra credit effort of one of our graduate students, you too can convert a vector based clip art file (.svg) into a 3D printable file (.stl). Follow these simple steps using free software (Gimp, Inkscape, and Tinkercad)*:

Step 1: Find or create a clean clip art style one color logo.

Step 2: Open image in GIMP or Microsoft Paint, which are both free, raster-based image editing software programs.

Step 3: Go to the “file” menu. choose “export.”  Make sure the file name ends in .png and select PNG file format from drop down menu. Select “save.”

Step 4: Open file in Inkscape, which is a free, open-source vector image software program.

Step 5: In Inkscape select the portion of the image desired.  Go to “path” menu. select “trace bitmap.”

Step 6: Next “check” the box at “remove background.”  Select “Ok.”

Step 7: Go to the “File” menu.  Select “Save as.”  Go to the “Save as type” drop down menu and select “Plain SVG.”  Select “Save.”

Step 8: In TInkercad or Autodesk 123D Design go to the file menu and select “import”.  select your SVG file and select “Open.”

Step 9: From there, you can further manipulate your 3D object.

MAKE things move with simple motorized circuits

Using inexpensive materials, you can MAKE things move by creating a simple motorized circuit. When you attach the motorized circuit to a base (a toothbrush head, plastic cup, etc.) you can make an analog ArtBot that is capable of creating a variety of randomized art. With endless possibilities, what will you design your ArtBot to do?

EDUCATIONAL EXTENSIONS
With all the digital technology around us, why would we want to make analog robots? Using inexpensive materials these little bots are a great introduction to circuits and allow for great engineering explorations involving simple design changes to experiment with cause and effect. There are even science competitions for these little bots: BrushBot Olympics, BristleBot Educational Robotics Competition, and many more. Even if you can’t physically compete in one of these competitions, try out some of their ideas and start your own competition with friends in your neighborhood or at your school.

MAKE things light up with simple circuits!

Circuits are all around us but we normally don’t pay much attention to how they work. A circuit is a loop that connects volts from a power source (such as a battery) to an output (such as a light or motor). Learn more about the technical aspects of circuits from this tutorial on SparkFun.

In addition to traditional electronic components, circuits can be made out of a variety of conductive materials, such as conductive thread, conductive tape, or even conductive ink.

Our favorite introduction to circuits is to make things light up. Combining an LED light and a coin-size battery (3 volt CR2032 batteries are our favorite) you can make a simple circuit connection that has a lot of creative potential. Simply attach tape or a binder clip to keep the circuit connected and consider what you can turn it into…a ring, a pendant, a bow tie, a hair bow? The possibilities are endless! Follow these simple steps to create your own: LED bling tutorial

Advanced electrical concepts can be explored by extending this same concept of simple circuits into soldering electrical components to a printed computer board. We like to start to learn how to solder with this tutorial that creates a blinking LED badge.

Soldering is serious business and needs to have a lot of safety considerations, but with the proper precautions we believe that children of all ages can successfully and safely learn to solder as long as they have appropriate adult supervision. Learn more about soldering basics here and be sure to check out our favorite one-page soldering guide here designed by Super Awesome Sylvia.
