Chemical Footprint—Family Activity
Source Institutions
In this multi-part activity learners examine non-point water pollution.
Identifying Erosion
Source Institutions
In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.
Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.
Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Breaking the Tension: Surface Tension 1
Source Institutions
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
