  4. 7th grade science BrainPop Weathering Dark Matter

  5. 7th grade science Definitions Weathering- breaking down of rock over time. Dark Matter

  6. 7th grade science Definitions Mechanical weathering-breaking down rock into smaller rocks by water, ice, wind, and organisms. A physical change of rock. Dark Matter

  7. 7th grade science Definitions 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. Dark Matter

  8. 7th grade science BrainPop Erosion Dark Matter

  9. 7th grade science Definitions Erosion-the carrying away of rock or sediments. Wind, water, and ice carve out Canyons and Valleys . Dark Matter

  10. 7th grade science Definitions Deposition - the dropping off of sediments or rock to a new location. Deposition creates landforms like deltas, sandbars, or sand dunes. Dark Matter

  15. 7th grade science Page Shake Rattle and Roll In your notebook: Objective: To examine and compare the chemical and mechanical weathering of limestone and granite rocks. Hypothesis: Predict whether or not limestone or granite will experience the most weathering. If___, then___.

  16. 7th grade science April 27th Shake Rattle and Roll Procedure: Place 1 piece of limestone and one piece of granite on your timeline. Make observations in your comp book. Add all rocks to the container. Fill container with water. Shake the rocks vigorously for a total of 15 minutes. Remove 1 granite rock and 1 limestone rock every 3 minutes. Place them on your timeline, record observations on your timeline.

  18. 7th grade science Page Shake Rattle and Roll In your notebook answer the following: Conclusion Was your hypothesis correct? How do you know? What does that tell you about limestone and granite?

  19. Chemical Weathering Page Add 5 drops of HCL (Hydrochloric Acid) to the granite. Add 5 drops of HCL to the limestone. Record your observations. What is happening?

  20. Clean Up • A Make sure all water is poured out into the sink • B Return Materials • C Wipe off desks • D Check and clean floors around desk
