Have you ever seen a fossil? A fossil is any evidence of past life preserved in sediments or rocks. Do you think you could have dinosaur fossils in your family car’s gas tank? Did you ever hear that oil and natural gas are “fossil fuels”? Do you think oil and natural gas can be made from fossils? How long do you think it takes fossil fuel to form?
Human activities can have a detrimental effect on animal habitats. Young students can witness the effect of water pollution on river habitats.
This activity will have students collect data, graph it, and compare the information to what they already know about radioactive elements and dating the planet's age.
Glaciers can create lakes, valleys and areas known as kettle marshes. Their weight and movement are the tools a glacier uses to shape the landscape. Use this experiment to look at small "glaciers" and how they shape the landscape around them.
The atmosphere is a mixture of gases. Similarly, the world's oceans and fresh waters contain dissolved chemicals. Many substances dispersed in air or water are measured in parts per million. Some of these substances are colorless, odorless, and tasteless, yet even in small quantities they can be toxic. To develop an understanding of parts per million as a concept, teams of students will create successive dilutions of a solution to reach a parts-per-million concentration.
Water that accumulates beneath the surface of the Earth is called groundwater. Contrary to popular belief, groundwater does not form underground "rivers," but is actually found in the small spaces and cracks between rocks and other material such as sand and gravel. The following activity involves learning how water moves through rock materials such as sand, gravel, and clay.

As a citizen scientist, you can use a soil test kit to find out how much of each type of chemical is in your soil.
Imagine playing beside the ocean, when suddenly, the water drops. Where the water used to be, there are wriggling fish and ribbons of seaweed. What do you do?
The goal of this activity is to identify the watershed you live in, the source of water you use at home and the pathway of surface water runoff in your watershed.
