Review and apply key grade-4 science ideas, energy transfer, waves and information, Earth's changing surface, and structure and function in living things, in a mixed practice format.
This week's spiral review reaches back to fourth-grade science. Remember energy transfer: energy can move from one object or place to another, such as through motion, heat, light, or sound, and can be transformed from one type to another, like a moving object's energy converting to heat through friction. Remember waves: vibrations that carry energy and can carry information, like sound waves carrying your voice or light waves letting you see.
Also remember Earth's changing surface: slow processes like weathering and erosion, and fast processes like earthquakes, reshape the land over time. And remember structure and function in living things: an organism's body parts are shaped to do a specific job, like a bird's wing shaped for flight or a plant's roots shaped to absorb water.
Mastery looks like: They can correctly answer mixed review questions spanning grade-4 energy transfer, waves, Earth's surface change, and structure and function ideas.
Common stumbles: Confusing energy transfer with energy disappearing; forgetting that Earth-surface change can be slow, erosion, as well as fast, earthquakes.
