Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.
Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
Water "Digs" It!
Source Institutions
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.
The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
Mechanical Grabber
Source Institutions
In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.
Forward-Reverse Switch
Source Institutions
In this activity, learners build a switch to turn electrical circuits on and off.
Puff Mobile
Source Institutions
In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.
Film Canister Rocket
Source Institutions
In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Translating an Alien Message
Source Institutions
In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa
Stretch the Chain and See the Light
Source Institutions
In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.
Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Carbon Configurations
Source Institutions
In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Make a Mobile!
Source Institutions
In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
