Earth's Systems

Climate and Temperature

Learn how Earth's climate effects soil types all over the planet.

Connect the Spheres

This activity will provide you with an introduction to a series of lessons — Survivor Earth — about water resources on Earth. You’ll investigate Earth systems by making observations in nature and identifying systems in the natural world. Ultimately, you will understand how the four spheres, or systems, on Earth — biosphere, hydrosphere, geosphere, and atmosphere — are interconnected.

Connecting With Nature

Go on an adventure with the Blue Goose, the symbol of the National Wildlife Refuge System!

Conservation in Action

Join the conservation movement with U.S. Fish and Wildlife Service!

Cookie Mining

The purpose of this activity is to give the player an introduction to the economics of mining. Each player buys "property," purchases the "mining equipment," pays for the "mining operation," and finally pays for the "reclamation." In return, the player receives money for the "ore mined." The object of the game is to develop the mine, safeguard the environment, and make as much money as possible.

Core Sampling

Drilling is the only way to be sure that oil and gas fields exist and exactly what is present in the formation. Core samples reveal the physical and chemical nature of the rock. In this activity, you will create a model formation and “drill” for samples.

Cupcake Core Sampling

Trying to "see" what is beneath the surface of the Earth is one of the jobs of a geologist. Rather than digging up vast tracts of land to expose an oil field or to find some coal-bearing strata, core samples can be taken and analyzed to determine the likely composition of the Earth's interior. In this activity, students model core sampling techniques to find out what sort of layers are in a cupcake.

Deep-Sea Drilling

This activity enables students to estimate and calculate scales of distance and length as used by ocean drilling scientists.

Dig Into Soil

Learn how soil scientists observe and record data and how that information is useful to farmers, builders, and others in order to use the land appropriately.

Digging Into Soil

Materials

  • Piece of heavy duty PVC pipe about one inch in diameter and 10 inches long
  • Piece of wood doweling that will fit inside the PVC pipe
  • Hammer
  • Wood block
  • Leather garden glove
  • Hand lens or microscope
  • Non-toxic marker
  • Large sheet of white posterboard
  • Six clear plastic sandwich bags
  • Plastic knife
  • Tools for separating soil, such as tweezers, tongue depressor, drinking straw
  • Paper towels (for clean up)
