Participants will use scientific practices to investigate answers to questions involving the color of the sky, sunsets, the Sun, and oceans. This activity requires use of a clear acrylic or glass container to hold water, a strong flashlight,... (View More)
Learners will weigh themselves on scales modified to represent their weights on other worlds to explore the concept of gravity and its relationship to weight. They consider how their weights would be the highest of all the planets while standing on... (View More)
This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)
Learners will model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it... (View More)
This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)
Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (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)
This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing... (View More)
This is an activity about the rotation of the Earth and Sun, and the Earth's revolution around the Sun. In chalk, learners will draw the Sun-Earth system, complete with Earth's orbit, and then act out the rotation and revolution of a yearly cycle.... (View More)
This is an activity about the Sun, Earth and Moon and their movements during solar and lunar eclipses. Students observe and manipulate a styrofoam ball model and simulate the movement of these bodies during the different kinds of eclipses. Learners... (View More)
