Water and Weather UnitWeek 12
Directions1. Prepare your desk for science.2. Use voice level 0 (no voice) to look at textbook
pg. 182 – 185 and think about what we learned about Earth’s water from yesterday’s lesson.
Targets & Warm UpTargets:Students will identify and illustrate Earth’s saltwater and freshwater features.
Warm Up: What have we learned about water on Earth? What do you know about saltwater and freshwater?

Earth’s Water
Types of WaterSaltwater vs. Freshwater
• Not healthy for drinking• Your body cannot use salty
water• Salt comes from rocks and
soils on the land• Rivers carry dissolved salts to
the ocean and seas• Most common salt in
saltwater is sodium chloride
• Healthy for drinking• Liquid freshwater• Underground• In lakes, rivers, streams
• Frozen freshwater• Glaciers and ice caps
• Also found in the atmosphere• Water vapor in the air• Rain, snow, hail

Glaciers
OceanA large body of saltwater that surrounds a
continent.
Sea
A large body of saltwater that is often connected to an ocean.
A sea may be partly or completely surrounded by land.
River
A large, flowing body of freshwater that usually empties into a sea or ocean.
StreamA body of running freshwater that flows into rivers.
LakeLarger areas of freshwater water surrounded by land.
Pond
Smaller areas of freshwater surrounded by land.
GlacierHuge sheets of frozen freshwater (ice and snow) that cover land.They are found where temperatures are very cold – high in the mountains or near the poles of Earth.
Glaciers• A glacier is a huge slab of ice and snow.• Glaciers form when the amount of snow that melts in
the summer is less than the amount of snow that falls in winter, resulting in a slow buildup of snow and ice.
• Glaciers "flow" downhill, eventually reaching the ocean.• At the coast, the ice extends out beyond the land,
floating on the water.• Eventually, a chunk of ice (iceberg) will separate from
the glacier. • Glaciers are made from snowfall, which is freshwater.
