Making Craters

This week we are learning about the planet Mercury. For our science experiment yesterday we made craters. I found two different experiments that we tried. First came from a library book we checked out title Mercury by Steven Kipp

First fill a basin with mud or clay

Give the children different size stones or mud balls and have them throw them into the basin. My kids were very timid with this so....

We let Daddy have a go. He made the best crater:)

Remove stones and examine your newly made craters and observed the changes in the mud/clay.

The next experiment we tried was from the book Solar System by Janice VanCleave's.
In this experiment we were trying to see how to measure the depths of a crater. I will have to try my best to describe this as only a few pictures were taken in our excitement of making craters:)

Fill a flat bottom bowl with cornmeal or sand. Place a flat side toothpick
into the sand and use a marker to measure how far the sand comes up the toothpick.
Next drop in marbles or stones into the sand at varying heights (we used a ruler) take the same toothpick as before and place into the middle of one crater and mark where the sand is. There should be difference in the marks and we discuss why.

Daddy having a go in trying to get a meteor to skip on the sand.

After wards we went to the internet and found this site that does computer simulated asteroid hits on earth and what the damage might be.

We had a great time with these experiments and it was nice to have Daddy home to help us:)


  1. what a neat unit study! I am about to order an astronomy curriculum to do with my youngest 3- you've given me some ideas, thanks!

  2. That is awesome! I can't wait to dive into astronomy with my children....and this looks like so much fun. Dropping in and following from the Hip Homeschool Hop!

  3. Great idea! I'm glad to see this post. We are going to be starting planets very soon, too! Following from the HHH.

  4. I always love doing experiments with my children~~Great blog..Following you from Tuesday Blog Trail via emails & GFC~~Shari


  5. How hard is it to homeschool?? I'm rather tired of the learning my children are getting at school and the bullying of other children is freaking me out...I'm SERIOUSLY considering homeschool but fear holds me back...how does one take that first step?? Thanx for your post...I quite enjoyed it!

  6. Hi Hen Jen,
    Thanks for stopping by and commenting. We are really enjoying our solar system studies.

  7. Hi Rebecca,
    Thanks for commenting and visiting. There is so much information on the solar system have fun learning with your kids.

  8. Hi Heavensent1, 1grown2togo, and live,love and educate - thanks for following and I am following back:)

  9. Great post Anna-Marie! It is always nice to see dad involved. He looked to be having all the fun. lol You are doing some really interesting and creative things with this unit study.

    I voted for you!

  10. Thanks Lynda
    It was nice having my husband home for the school day and he got to see what it is I do with the children:)

  11. Wonderful post Anna-Marie!
    I sometimes save science experiments (the few that I do with my kids) for evening when my husband is home so he can join in and help out and so I can take pictures :) It looks like you are having fun with your astronomy unit. I will have to refer back to your posts whenever I teach astronomy to my kids. :)

  12. This is a great experiment! I'll have to try it sometime soon!
