Activities from Across the Earth System

What is the Earth System?

• The atmosphere (Air) extends up from the Earth surface for several hundred kilometers.

• The biosphere (Life) is all living things, from single-celled bacteria to plants and animals.

• The geosphere (Land) includes all minerals, rocks, molten rock, sediments, and soils (Note there is life in soil as well.)

• The hydrosphere (Water) includes the ocean, rivers, lakes, streams, groundwater, water vapor.

• The cryosphere (Ice) is the frozen part of the Earth system and includes snow, glaciers, and sea ice.

Workshop Overview

Let’s Make Oxygen

This demonstration will explore chemical changes and introduce some of the properties of oxygen.

Exploring Density of Freshwater and Saltwater: Par 5

• An introduction to the interaction of fresh and salt water (estuarine systems)

• An introduction to a discussion of

density

Adaptation Investigation

Investigate how shape and structure of beaks affects the type of food that birds are able to eat

Toucan• The toucan's beak

is adapted to grab and crush fruit and nuts.

• It is strong like a nutcracker.
