Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
Blowin’ Up a Storm of Oil
Source Institutions
In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
Be a Plumber
Source Institutions
In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.
Bouncy Egg
Source Institutions
In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.
Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.
Hexagon Hunt
Source Institutions
This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.
It's Natural
Source Institutions
This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.
