Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Fork in the Road
Source Institutions
In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

Plant Parts You Eat
Source Institutions
In this food science activity, learners observe different plant-originated foods.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Habitat Web
Source Institutions
In this activity, learners explore the web of connections among living and non-living things.

Two-String Yo-Yo
Source Institutions
Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

Paper Chain Testing
Source Institutions
Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

Roller Coasters
Source Institutions
In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

Push Me a Grape
Source Institutions
In this physics activity, learners experiment with the attractive and repulsive power of magnets.

Build-A-Membrane
Source Institutions
In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Signs of Life
Source Institutions
In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

Measuring Earthquakes
Source Institutions
In this activity, learners build their your own seismograph with household materials to document shaking.

Finger Knitting
Source Institutions
In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

Digestive System: A Kinesthetic Lesson
Source Institutions
In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

Where the Buffalo Roam
Source Institutions
In this activity, learners explore the Great Plains.

Cut-Fold-Staple
Source Institutions
In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.

Lava Layers
Source Institutions
In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.
Shadow Puppets
Source Institutions
If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.
