- Although sand looks like it is brown, it is actually made up of different minerals that are pink, black, and white.
- In order for your students to experience this, have them use magnifying lenses to separate the components of sand into separate piles using toothpicks.
- Have them examine each of the different particles closely, writing down observations about each.
- Usually sand consists of calcite, mica, feldspar, and quartz. Have books available for students to do further research on the different components of sand.
- Also have students rub the individual grains against a glass jar to see which ones scratch it. They should add this to their data.
