Mid summative 1 answers 2010

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