Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.
Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.
Design and Build a Better Candy Bag
Source Institutions
In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.
Currently Working
Source Institutions
Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.
Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
Sky Diver
Source Institutions
Students design and build their own parachutes in this hands-on engineering project.
Train Your Brain
Source Institutions
In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.
How is Coastal Temperature Influenced by the Great Lakes and the Ocean?
Source Institutions
In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.
Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Tower of Coins
Source Institutions
In this physics activity, challenge learners to remove the bottom coin of a stack of nickels without knocking over the stack. Use this activity to demonstrate friction.
Balloon Flinker
Source Institutions
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
Dance Diagram
Source Institutions
Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.
Plants: Hanging Tough
Source Institutions
In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge
Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.
CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
Feather Rockets
Source Institutions
In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.
Give Me a Brake
Source Institutions
In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.
