Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Wind Tubes
Source Institutions
In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Topological Puzzles
Source Institutions
In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.
Papermaking at Home
Source Institutions
Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.
Spaghetti Bridge
Source Institutions
Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.
Build a Tree
Source Institutions
This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
Electric Cup Guitar
Source Institutions
Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.
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.
Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
Cardboard Automata
Source Institutions
Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.
Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.
Propeller-Powered Car
Source Institutions
In this activity, learners construct cars that are powered by hand-made, electric propellers.
Cardboard Opaque Projector
Source Institutions
In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
Wire Maze
Source Institutions
Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.
