HS-ESS2-1

Develop a model to illustrate how Earth's internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.

Dating Popcorn

How do geologists understand the Earth’s history? In part, they measure the age of rocks and other natural materials by dating techniques. They can date rocks by gauging the amount of decay of radioactive elements. You can simulate the dating process with popcorn.

EarthCaching

EarthCaching is an exciting educational activity through which you can learn about Earth and the natural processes that shape our planet over time. By combining GPS technology with outdoor field experiences, EarthCaching allows students and others to experience the wonders of Earth in an entirely new and entertaining way.

Erosion in a Bottle

Soil erosion is the process of moving soil by water or wind — this happens naturally or through human interference. Preventing soil erosion is important because nutrients are lost, and sediment that accumulates in waterways impacts life there. Conserving soil depends on how it is protected by plants and coverings.
You will model erosion by water and compare the amounts of runoff and soil loss generated from three different ground cover types.

Glacier Slide

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.

Identifying Your Watershed

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.

Maintaining Soil Moisture

Soil is a vital component of almost every ecosystem, and its health often determines the viability of the whole ecosystem. If a soil cannot support the living organisms within it – such as insects, bacteria, fungi, and plant roots – then it is likely that the entire ecosystem will suffer. The same is true on farms. The success of crops is dependent on the health of the soil.

Sinkholes in a Cup

In this activity, learn how sinkhole formations in rocks form and the danger they pose to communities.

Sources of Minerals

We are surrounded by objects that we depend upon for our everyday lives. From our clothes to our phones, bikes, cars, showers, plates, chairs, televisions, computers, and nearly everything else, we rely on objects made of a variety of materials. But where do those materials come from in the first place, and what happens when we run out of them?
