Learners create edible models of the interior composition of the Earth and Moon. Common food items are used to construct the cores, mantles, and crusts of both planetary objects. They then compare their structure as they are eating their models.... (View More)

This simple exercise demonstrates how Maya numbers are written and how higher place values of numbers are calculated. This activity can also be used in informal education settings with people ages 9 through adult. Includes information for educators,... (View More)

Learners and their families are encouraged to go outside on a clear evening and view the sky to see the planets for themselves. Using sky charts and other resources, and possibly in partnership with a local astronomical society, children navigate... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this activity, learners select the scientific instruments for their satellite, calculate the power requirements for all the subsystems, and construct a scale model of their very own Earth observing satellite using building blocks and/or Legos.... (View More)

This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. This resource is from PUMAS - Practical Uses of Math and Science - a... (View More)

In this introductory activity, learners investigate and discuss infrared images of various everyday objects, such as toasters, hairdryers, and running water, to learn about infrared imaging. Student questions about the false-color images help guide... (View More)

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS -... (View More)

In this field activity, students document examine the role of a tree in its ecosystem and as part of the environment in a human community. Students measure the tree's dimensions, examine co-residing organisms, leaf litter, and soil, and research the... (View More)

In this laboratory investigation, student teams discover that the ocean's capacity to dissolve carbon dioxide depends on its temperature, and consider the effect of a warming ocean on CO² absorption. The activity requires Bromothymol blue indicator... (View More)
