2. Lesson 1
Water Cycle
5th Grade Earth Science lesson 1

3. Big Idea
Water on Earth moves between the oceans and land through the processes of evaporation and condensation.
Most of Earth’s water is present as salt water in the oceans, which cover most of Earth’s surface.
When liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.
Water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow.

4. evaporation when a liquid turns into gas
5th Grade Earth Science lesson 1

5. condensation
When water “sweats” or the process by which a gas changes into a liquid. Clouds and fog are formed by condensation.

6. water vapor when water turns (evaporates) into a gas.
5th Grade Earth Science lesson 1

7. Precipitation
water that falls from clouds to Earth Precipitation can be solid like snow or liquid like rain.

Lesson 2
Fresh Water Resources

9. Big Idea
The amount of fresh water located in rivers, lakes, underground sources, and glaciers is limited and that its availability can be extended by recycling and decreasing the use of water.
Students know the origin of the water is used by their local communities.

Lesson 3
Air Movements

17. The Big Idea
Energy from the Sun heats Earth unevenly, causing air movements that result in changing weather patterns.
The uneven heating of Earth causes air movements (convection currents).
The ocean has influence on the weather and the role that the water cycle plays in weather patterns.

19. water cycle
the constant movement from the ground (Earth’s surface) to the atmosphere and back again to the ground (Earth’s surface).

20. climate The weather conditions such as: Temperature Air pressure
Humidity
Precipitation
Sunshine
Cloudiness
Winds
throughout the year.
5th Grade Earth Science lesson 3

21. 5th Grade Earth Science The Big Idea Lesson 4 Air Pressure
The Earth’s atmosphere exerts a pressure that decreases with distance above Earth’s surface and that at any point it exerts this pressure equally in all directions.

22. air pressure
the weight of air in the atmosphere pressing down equally and evenly in all directions
5th Grade Earth Science lesson 4

23. atmospheric pressure
the weight of air in the atmosphere, the higher you go into the atmosphere the less air weight there is above you

24. 5th Grade Earth Science Air Masses and Fronts The Big Idea Lesson 5
Students will know the causes and effects of different types of severe weather.
Students will learn how to use weather maps and data to predict local weather and know that weather forecasts depend on many variables.

30. Earth Science Lesson 6

31. The Big Idea
The solar system consists of planets and other bodies that orbit the Sun in predictable paths.
The Sun, an average star, is the central and largest body in the solar system and is composed primarily of hydrogen and helium.
The solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets.
The path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.

36. gravitational force
Gravitational force causes a pull between the mass of a planet and the mass of the sun. It makes the planet orbit around the sun.
