What do you think the moon texture is like? These two contrasting textures are often what people envision!
Experiment #1 Materials:
Play Sand (colorful sand or plain)
- Rectangular baking tins or dish
- Glitter (if desired)
Step 1: First, measure 3 ½ cups of sand add it to your empty dish.
Step 2: Next, add 1 ¾ cups of cornstarch and mix well.
Step 3: Lastly, add ¾ cup of water and mix.
Touch! What texture do we have? What kind of descriptive words can you use to describe the texture of the moon sand?
Experiment #2 Materials:
- Medium Bowl
Step 1: First, measure 1 cup cornstarch and add it to your bowl.
Step 2: Next, add ½ cup of conditioner and mix well.
Touch! What texture do we have? What kind of descriptive words can you use to describe the texture of the moon dough?
- Tip: Fold in food coloring and/or glitter into the dough to and color for a new look, if desired!
Science Behind It:
Compare your moon sand and/or moon dough to astronaut Buzz Aldrin’s description:
Below is an excerpt from a larger interview by Scholastic Students from November 1998, where they interviewed Buzz Aldrin, the second man to walk on the moon.
The students asked: “What did it feel like to walk on the moon? Is its surface different from that of Earth?”
Buzz replied: “The surface of the moon is like nothing here on Earth! It's totally lacking any evidence of life. It has lots of fine, talcum-powder like dust mixed with a complete variety of pebbles, rocks, and boulders. Many pebbles, fewer rocks, and even fewer boulders naturally make up its surface. The dust is a very fine, overall dark gray. And with no air molecules to separate the dust, it clings together like cement. If you examine it under a microscope, you can see it's made up of tiny, solidified droplets of vaporized rock resulting from extreme velocity impacts, like an asteroid from outer space hitting the surface over millions of years.”
