Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Trophy Triathlon
Source Institutions
In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

Flubber
Source Institutions
Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

Cryptographic Protocols: The Peruvian Coin Flip

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.

Exploring Materials: Graphene
Source Institutions
In this activity, learners investigate the properties of graphene and graphite.

Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Unlocking the Secret in Product Codes
Source Institutions
In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.

Ewok Escape
Source Institutions
The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

Vocal Visualizer

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Overnight Painting Machine: Pico Cricket Activity
Source Institutions
This activity requires a Pico Cricket (tiny computer).

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

Stomp Rocket
Source Institutions
In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

Build a Better Roof
Source Institutions
In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.
