Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
Coffee Filter Rainbows
Source Institutions
In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
X-Ray Spectra
Source Institutions
In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
Decomposition Column
Source Institutions
In this activity, learners turn empty 2-liter bottles into a see-through compost container.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
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.
Light of the Moon
Source Institutions
Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
