Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.

Paperfolding Polyhedrons
Source Institutions
In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

Biomimicry Mash-Up
Source Institutions
In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.
Pattern Families
Source Institutions
In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

For the Birds
Source Institutions
In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

DIY Pasta Rover
Source Institutions
In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.
The Right Fit
Source Institutions
In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

Party Hat Symmetry
Source Institutions
In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

What Can You Make of It?
Source Institutions
In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

Curious Contraptions
Source Institutions
In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

Stack 'Em Up
Source Institutions
In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

Moo Glue
Source Institutions
Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Fly on the Ceiling
Source Institutions
In this math lesson, learners play two different games to help them understand coordinates. First, learners read the book, "The Fly on the Ceiling," by Julie Glass.

Magnetic Seesaw
Source Institutions
In this activity, learners build a seesaw powered by magnets.

Carousel Pump
Source Institutions
In this activity, learners build a carousel toy that spins when pushed down.

Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

Engineering For Earthquakes
Source Institutions
In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.
