Rock Cycle - Minerals (2B)

PROBLEM: How do crystals grow?


MATERIALS: salt, laundry bluing, ammonia, water, baby food jars


Step 1. Take one clean baby food jar. Take a piece of masking tape and write your name on it with a crayon. Tape it to the lower side of your jar.

Step 2. Add rocks to your jar until it is 1/3 full. Add 5 ml salt. Add 5 ml of water. Add 4-6 drops of food coloring. You get to choose which color you want!

Step 3. Now have your teacher add 5 ml each of ammonia and laundry bluing. Carefully carry your crystal garden to the place your teacher has selected. Over the next week or so you will be able to see your garden grow! Keep a record of what you see by drawing a picture of your garden every day.











CONCLUSION: Describe what happened to your crystals after a week.
