Learning about Earth’s Past through Creative Writing

Learning about Earth's Past through Creative Writing

Most kids love to be creative and make up stories. Use that creativity to research Earth’s past. Depending on the age of the child, you might want to first introduce them to the Geologic Time Scale. Here’s a good website with some basic information from Britannica Kids. For younger children, you might just help them pick a topic from Earth’s past, such as “dinosaurs.”

Next, help your student narrow down a specific time period (or topic) that sounds interesting to them. Help them research what the Earth was like during that time. Consider including the plants and animals that lived during that time, the climate, and what the land and oceans were like.

After your child has collected information appropriate for their age, challenge them to write a story about the time. Here are a few ideas to help get you started:

1. Write a first person story involving a time machine that takes them back to that time period for a week.

2. Write a story from the point of view of an animal that lived during that time.

3. Write a story about an alien who visits Earth during that time period.

If you give your child the freedom to make up their own creative story about their time period or topic, they are sure to have fun while learning quite a bit about Earth’s history!

Cotton Cloud Model

Cotton Cloud Model

If you’re teaching your kids about the different types of clouds, have them make a model to show cloud structure and the different levels of the atmosphere where clouds form. Here’s a good website that covers the basics of cloud classification. There’s a good diagram of different types of clouds and the atmospheric levels in which they form. For younger children you might want to let them use the image as a guide for their model. Older children will find it more challenging to only research information about the structure and level of different types of clouds and then develop their own visual model.

Whichever option you choose, provide blue foam board, plenty of cotton balls, school glue, and markers. Challenge your child to plan their model before beginning. Discuss the need to arrange the cotton so that it represents the structure of different types of clouds. And, the need to plan ahead to divide the poster into sections to represent the different levels at which clouds form. A black marker can be used to darken the cotton of the “rain clouds.”

Extend the cloud lesson by taking the finished model outside on different days to identify clouds in the sky. The model will help children understand that they are actually looking up through three different levels of clouds.

Making Rocks Fun!

Making Rocks Fun!

Okay, I have to admit, rocks sound boring to most people. But here’s a way to get kids interested in the topic of rocks and minerals!

Kids (and adults) love to find treasure. Purchase a bag of “mining rough” and you have a ready-made treasure hunt for your kids. Mining rough is the left over material generated by the mining process. To a mine that recovers and sells gemstones, it isn’t cost effective to spend time going through the left over material to pull out the small gemstones. They bag it “as is” and sell it at very reasonable prices. Going through the bag is literally a treasure hunt and you can find some very nice samples of amethyst, crystal quartz, and other gemstones including small samples of rubies and emeralds. Nothing that’s really worth much money, but pieces that will excite your kids!

There are many mines that sell this “mining rough,” but here’s a link to the one I order from: Cold River Mining Company. They do sell wholesale, but this link will take you to their “store” where you can buy individual bags. If you have a cave attraction nearby, you can probably purchase bags of mining rough there.

You’ll also need a sieve to separate the dirt from the larger rock and mineral specimens. You can purchase one from the mine, but it’s much cheaper to make your own. I would suggest getting a 1-foot x 1-foot piece of window screen to use as a sieve. The fiberglass screen works much better than the aluminum wire screen. The cut ends of the aluminum around the edges can puncture the skin!

The mining rough is dirt and rock straight out of the ground, so it can be messy. This is a great outdoor activity when the weather’s nice! Put the kids in their bathing suit or old clothes you don’t mind getting dirty and wet.

Here’s how to mine for gemstone treasure:

1. While your child holds the screen, add a small amount of mining rough to the center of the screen.
2. Spray the rough with a garden hose set on a low setting. The dirt will wash off revealing the rocks and minerals. (You can also dip the screen in a bucket of water, but the garden hose is much more fun!)
3. Collect the large pieces from the screen and let them dry.
4. The bags of mining rough usually come with an identification guide that kids can use to identify their gemstone treasures.

Be sure to explain to your budding geologists that gemstones are rocks and minerals that formed deep inside the Earth. Because the Earth is always moving and changing, sometimes these rocks and minerals get pushed up close enough to the surface for us to dig them up.
