Overview

Oceans contain 97% of the water on the Earth and are home to a huge number of living creatures. Most of these creatures, about 90% of them, live near the water’s surface, where the pressure is not so great and they can get some light.

The classroom resource provides a slide show that will explain why the ocean is salty and describe different organisms that live in the ocean. There is also a short test that can be used to assess students' understanding.

SC15.2.10

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).

UP:SC15.2.10

Vocabulary

  • Collect
  • Evaluate
  • Solid
  • Liquid
  • Glaciers
  • Oceans
  • Lakes
  • Rivers
  • Streams
  • Frozen
  • Ponds

Knowledge

Students know:
  • Water is found in many places on Earth.
  • Water exists as solid ice and in liquid form.

Skills

Students are able to:
  • Identify which sources of information are likely to provide scientific information.
  • Collect and evaluate data to identify water found on Earth.

Understanding

Students understand that:
  • There are observable patterns as to where water is found on Earth and what form it is in.

SC15.5.15

Identify the distribution of freshwater and salt water on Earth (e.g., oceans, lakes, rivers, glaciers, ground water, polar ice caps) and construct a graphical representation depicting the amounts and percentages found in different reservoirs.

UP:SC15.5.15

Vocabulary

  • Fresh water
  • Salt water
  • Oceans
  • Lakes
  • Rivers
  • Glaciers
  • Ground water
  • Polar ice caps
  • Reservoir
  • Graph

Knowledge

Students know:
  • Nearly all of Earth's available water is in the ocean.
  • Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.

Skills

Students are able to:
  • Graph the given data (using standard units) about the amount of salt water and the amount of fresh water in each of the following reservoirs, as well as in all the reservoirs combined, to address a scientific question:
    • Oceans.
    • Lakes.
    • Rivers.
    • Glaciers.
    • Ground water.
    • Polar ice caps.
  • Use the graphs of the relative amounts of total salt water and total fresh water in each of the reservoirs to describe that:
    • The majority of water on Earth is found in the oceans.
    • Most of the Earth's fresh water is stored in glaciers or underground.
    • A small fraction of fresh water is found in lakes, rivers, wetlands, and the atmosphere.

Understanding

Students understand that:
  • Standard units are used to measure and describe physical quantities such as the amounts of salt water and fresh water in various reservoirs.
