Oil and Soap
Source Institutions
Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.
Anti-Gravity Cups
Source Institutions
In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
ANTacid: Indicator Paper on an Anthill
Source Institutions
In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Super Shrinkers
Source Institutions
In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.
Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
The Incredible Journey
Source Institutions
In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.
Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
Salt Crystal Garden
Source Institutions
In this activity, learners will explore saturated solutions and discover how crystals form.
How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.
Atmospheric Collisions
Source Institutions
In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.
Solar Cell Simulation
Source Institutions
In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.
Terrestrial Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.
