The students did an amazing of presenting what they know. ¬†I was very impressed with their ability to memorize and present speeches with great eye contact! The time and effort that they put into their projects was certainly evident! Thank you for supporting us and for stopping by to listen to some of our students. We couldn’t have done this without you!

 

 








Rocks & Minerals

Posted on

We are currently working on a review sheet for the Earth Materials unit. The test will not be until Friday, April 29th (although I may push this date back once I see how long the M-Step takes). Feel free to review these concepts with your child:

  • Sedimentary rock is formed in layers and has many fossils.
  • You can decide the age of a rock layer by finding its position in a series of layers because the top layer is the ¬†youngest and the bottom layer is the oldest.
  • Fossils are clues of past changes in the earth‚Äôs surface and climate. A seashell fossil found on land far from the ocean gives us a clue that the land was once under water.
  • Examples of parts of organisms that become fossils are the bones, skull, shell or teeth.
  • A mineral is a solid that forms naturally, is not alive, and has the same chemical make-up wherever it is found.
  • Rocks are made up of at least two minerals.
  • Minerals can be recognized by color, luster, texture, streak, and hardness.
  • Rocks formed in layers and usually formed near water are called sedimentary.
  • Rocks formed by changing materials under heat and pressure are called metamorphic.
  • Rocks formed when melted rock (magma) is forced up from the Earth and cools are igneous.
  • Rocks can change form from heat, pressure, and chemicals.
  • Properties used when observing rocks are their color and size.
  • Soil are small bits of crushed rock containing living or once living matter.
  • Sand are rocks broken into smaller pieces by water, wind, and pressure.
