Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
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.
Rusty Penny
Source Institutions
In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea
Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.
Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Excavating and Mapping Under Water
Source Institutions
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.
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.
Hot Equator, Cold Poles
Source Institutions
In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.
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.
Drying It Out
Source Institutions
In this activity, learners investigate and compare the rate of drying in different conditions.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
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).
Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).
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.
What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
