In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.
