Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
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.
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.
Identifying Erosion
Source Institutions
In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.
Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
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.
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.
Composting
Source Institutions
In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Living Bones, Strong Bones
Source Institutions
In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh
What is Light?
Source Institutions
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.
Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
How can Clouds Help Keep the Air Warmer?
Source Institutions
In this activity, learners explore how air warms when it condenses water vapor or makes clouds.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Carbon Dioxide Removal
Source Institutions
In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.
