Enjoying Earth Science

This year, our two daughters are studying earth and space science.  Our oldest daughter is using Christian Kids Explore Earth and Space, by Stephanie L. Redmond, and we couldn't be more pleased.  The informative text of each lesson is just long enough to create interest and the hands on activities are fun for the child and parent.  Here's a brief photographic tour of our oldest daughter's two most recent earth models.



A 3-D Model of Earth 

  

To show all the layers of the earth form the core to the crust,

she was instructed to form a small sphere of black clay for the core. 

Then, each layer was rolled out

and placed over the gradually enlarging sphere.

Rolling out another layer

The crust was added last. 

She used blue and green clay to depict land and water.

Next, she used dental floss to cut the model in half. 

She was able to see the layers of earth very clearly.

Plate Tectonics Demonstration

Tuesday, she completed the second earth model. 

This time she was directed to use an egg. 

I boiled it, and allowed it to cool. 

Then, my daughter rolled the egg on a counter top to crack the shell. 



She observed how the shell remained on the egg, but was broken. 

In places, the shell was raised, lowered, and overlapped. 

This was to demonstrate the plate tectonic theory she had just researched.



Today, I am linking-up with The Homeschool Village.  The topic this week is science.
