This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this activity, learners explore rocketry and the principals of space flight.

This is a series of demonstrations about different electrical and magnetic phenomena.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

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.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

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.

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

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.
