5. Dark Matter 7 th grade science Weathering BrainPop

6. Dark Matter 7 th grade science Weathering- breaking down of rock over time. Definitions

7. Dark Matter 7 th grade science Mechanical weathering-breaking down rock into smaller rocks by water, ice, wind, and organisms. A physical change of rock. Definitions

8. Dark Matter 7 th grade science Chemical weathering- breaking down rock through chemical changes. The rock is changed into a new substance because it reacts with water, oxygen or other substances. Definitions

9. Dark Matter 7 th grade science Erosion BrainPop

10. Dark Matter 7 th grade science Erosion-the carrying away of rock or sediments. Wind, water, and ice carve out Canyons and Valleys. Definitions

11. Dark Matter 7 th grade science Deposition - the dropping off of sediments or rock to a new location. Deposition creates landforms like deltas, sandbars, or sand dunes. Definitions

26. Succession Plot Check-In Week 2 Reminder of Outside Expectations: – Voice Level 1-2 (Voice Level 0 in Hallway) – No wandering – Stay on Task

27. Succession Plot Week 2 Check-In After 2 WeeksAbiotic/Biotic Factors Conclusion: How has your plot changed in the last 2 weeks? What type of succession occurred? Do you think any weathering, erosion, or deposition occurred? Why?

28. Timelapse: Erosion Timelapse Video: Waves Eroding Land on the Coast

29. Stream Table Lab Today you will investigate the effect that forces of nature have on the earth’s surface using a stream table.

30. Stream Table Lab A- Data Recorder B- Lab Manager C-Stream Table Setup D-Materials Manager

31. Stream Table Clean-Up Do NOT pour sand down the drain. It will clog! Drain water as much as possible, then pour dirt/sand into waste contained provided by teacher.

32. Stream Table Lab Debrief: Where did you see erosion occurring? Where did the Deposition occur? What real life landforms were represented in your stream table? Where does Weathering fit in all of this?
