Easy Outdoor Science Activities For Kids

Rainbow Rock Collection

The rainbow rock collection activity will dramatically increase the number of colors you can find in your own back yard. Collect some rocks and make a colorful rainbow!

What You'll Need:

  • Bag or plastic jar for collection
  • Glue or duct tape
  • Poster board

Nature has created hundreds of differently colored rocks. Many of them can be found in your own yard.

When you're feeling ready to explore, see how many different tones you can discover and collect in a single day's geological expedition.

If you want, you can mount the stones on a piece of poster board.

Just for fun, take your poster to a nearby natural history museum or geology professor. Ask why your rock specimens are the color they are. You might be fascinated to discover what chemicals work to give a rock its hue.

Now that you've looked at the different colors of rocks, you can investigate their different shapes with the next activity.
