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.
Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
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.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
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.
Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.
The Rumblin' Road: Determining distance to a Thunderstorm
Source Institutions
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
Quadraphonic Wind
Source Institutions
In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.
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.
Ocean Acidification in a Cup
Source Institutions
Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.
Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.
Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
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.
Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
Amazon Water Cycle Roleplay
Source Institutions
In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
Design and Build a Barometer
Source Institutions
In this activity, learners make a barometer, an instrument to measure change in air pressure.
