In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

Learners build a wind turbine and test it to see how much energy is created.

This detailed lesson plan for a field trip to Canyonlands National Park in Utah (page 32 of pdf) teaches students about the habitat of bighorn sheep.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

This activity introduces learners to wolf behavior and communication.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

In this activity, learners explore the invisible infrared radiation from an electric heater.

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners are challenged to design and build a system of gears and kinematics to create a hand-stamping machine.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.
