4. Apply

    • Activity: Sand Analysis
      1. Part I: Brown Sand
        • Label one cup "Brown" with a sharpie. Grab a small ball of brown sand and place it in your cup. Play with it by pulling it apart, squeezing it, etc. Add a few drops of water to the sand and notice what happens. Describe your observations in your notes.
      2. Part II: Yellow Sand
        • Label one cup "Yellow Sand" with a sharpie. Divide the cup in thirds with a pen. Fill to 1/3 mark with blue sand and to 2/3 mark with water. Stir with your spoon. Scoop out some sand with your hand. Describe your observations in your notes.
      3. Part III: Structure Analysis
        • Shown below are the interior structure of "Brown" (left) and "Yellow" (right) sand. Hypothesize a possible identify for the red "?" in each sand. Draw a hypothetical completed structure for each in your notes and on a whiteboard along with a short explanation.
