Monday: Erosion video http://studyjams.scholastic.com/studyjams/jams/science/rocks-minerals-landforms/weathering-and-erosion.htm Take the "Test Yourself" quiz at the end of the video.
Tuesday: Enrichment/Science Quiz
Wednesday:Demo day. Objects in motion tend to stay in that motion until acted upon. Demo. Two pool balls crash and both their directions change. Water stream demo from bottle. Use pvc pipe or combto show how an invisible force can affect trajectory. Let students try at their table. Next, planet/orbit/gravitydemonstration. Using a model Earth, demonstrate a tethered orbitng object. If spun too fast, it will fly away. If spun too slow, it will crash into Earth. Read 422-423 and record gravity, orbit, and inertia into notebooks.
Thursday: http://www.brainpop.com/science/weather/seasons/Use basketball/lightbulb in middle of room demo to show tilt of Earth. Identify four areas of room just as a different season (1-4), but do not name them. Ask what season it is for us at each of these times.
Read 424-426 and define revolution and rotation in notebook. Because the middle of Earth (equator is always pretty close to sun, it is less likely to change throughout seasons and stay warmer overall.
Friday: Finish science lessons. Short quiz on Seasons with Open Response question.
