Your child is learning about Water and air on Earth. In this unit, your child will:

· learn to identify where air and water are found on Earth and understands their importance
· learn that water can be saltwater or freshwater
· learn the basic characteristics of air and the composition of air
· learn how wind is measured
· learn what weather is and how to describe different types of weather
· learn to identify and make some instruments for measuring weather
· learn to differentiate between drinking water and non-drinking water
· learn how to save water
· learn the water cycle
· learn to listen to, read and understand a story about a drought

I'd like to remind you that I’ve added a new link about Science in Spanish to have a better understanding of each unit.

EARTH THE WATER PLANET

Water is found in many places in and around the Earth. 

It's found in three states. 

Most of the water on the Earth is saltwater, and only a little is freshwater.

FRESHWATER                                                                   SALTWATER

Rivers, lakes, icecaps and groundwater.                          Oceans and seas.

Reservoirs (man-made lakes)

AIR

Plants can't grow without air. People and animals can't breathe without air. Air is found mainly in the atmosphere, which is the layer of gases that surround the Earth.

WATER and AIR have the same characteristics: they have no smell, no taste and no colour.

Air takes up space.
