Transcript

  • 1. There are labels on the containers Observation
  • 2. All of the seeds were planted on the same day Inference
  • 3. Some of the plants were taller than others Observation
  • 4. They put different amounts of salt in the containers Inference
  • 5. One container has smaller plants because it has the most salt Inference
  • 6. This experiment is to determine how salt affects plant growth Inference
  • 7. The students are pleased with the way the experiment is turning out Inference
  • 8. Limestone
    • Reacts to acid test by fizzing due to presence of calcite
    • Rock #’s 11, 15
  • 9. Sandstone
    • Rock made of grains of sands “glued” together
    • Rock #’s 13, 16
  • 10. Shale
    • Smooth rock, does not react with acid
    • Rock #’s 12, 14
  • 11. Erosion and Deposition
    • Erosion: The wearing away of earth’s materials via water, wind, ice or gravity
    • Deposition: Sediment that is eroded is then “deposited” or put down someplace. This sediment eventually hardens and becomes sedimentary rock
  • 12. Observation and Inference Observation Inference Several different colored layers X Contained calcite X Environment when formed was a marine one X Reacted with acid x
  • 13. Limestone
    • Knew that it was limestone because it reacted with acid; sandstone and shale don’t react
    • Layers and shell fossils were also good indicators
  • 14. Erosion
    • Water : flowing water carries away particles of sediment and carves away the land
    • Ice : water seeps into rocks and freezes which, over time, causes the rocks to split
    • Wind : wind picks up small particles and carries them away
  • 15. Rock correlation
    • Mile 21
      • Supai Sandstone
    • Mile 41
      • Muav limestone
  • 16. Mile 35
    • Muav Limestone because it is directly below Redwall Limestone
