Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Heavy Lifting: Design Squad
Source Institutions
In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Building a Basic Series Circuit
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.
Pulleys
Source Institutions
In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.
Rice Handle
Source Institutions
In this physics activity, learners attempt to lift a jar full of rice using only a spoon.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
Action Figure
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.
You Can't Take It With You
Source Institutions
This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.
Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.
Coupled Resonant Pendulums
Source Institutions
In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t
Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
