A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Sizing Up Hail
Source Institutions
In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.
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.
Woodlands Map
Source Institutions
This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit
Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.
The Desert Blooms!
Source Institutions
This activity attempts to clear up the common misconception that deserts are always hot, totally dry, and uninhabitable.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.
Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.
DIY Weather Vane
Source Institutions
In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.
Ramp it Up
Source Institutions
In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.
Water Cycle in a Bag
Source Institutions
In this activity, learners will explore the water cycle by creating a small atmosphere.
Resource Hunt
Source Institutions
In this activity, learners explore nonrenewable resources and learn why these resources are finite.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
Where Does the Wind Blow?
Source Institutions
In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.
How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl
Paper Cup Anemometer
Source Institutions
In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.
Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
