With all of the posts and pictures about our science experiments and history projects, you are all going to think that those are the only subjects we do! *grin*
While we do many more subjects, I just don’t have any great pictures to share at the moment. I’ll work on that.
I am a firm believer in letting kids get hands-on in their studies and discover how and why things happen.
Renée (14) has been working on studying the layering (stratification) of sedimentary layers. We turned to the tried-and-true mason jar experiment to see the effects.
First, we gathered up different kinds of soil from around the yard…
A good shake gets the sediments well mixed into the water…
We sat the jar to the side for about 20 minutes to allow the layers to separate and settle…
The next morning the water was clear and the sedimentary layers were obvious. How quickly layers separate and settle!
We are going to upgrade this experiment a little by adding rocks and a few different types of bones to see how they layer.
Hannah (9) has been studying the sun in her Exploring Creation with Astronomy book. What do you get when you mix the sun and water? Rainbows!
We headed outside to create our own rainbow.
She was fascinated to discover the rainbow’s name, ROY G. BIV.
Emily Grace (11) has been studying crystal shapes and formation in her science, God’s Design for Chemistry.
Here is a simple experiment to form two different shaped crystals with every day household products.
You will need:
- 2 plates
- 2 pieces of dark construction paper
- epsom salt
- table salt
- a small pot
First, cut the paper to fit neatly on top of the plate. Next, boil 2 tablespoon of epsom salt in 1/2 cup of water. When the salt is dissolved, pour it over the construction paper. You want the construction paper to be thoroughly wet but not soaked. Repeat this for the table salt and pour it onto the second plate.
Set the plates to the side where they can dry undisturbed. When all of the water has evaporated, you will notice crystals have grown on the underside of the paper.
Emily Grace noted that the table salt formed little mini ice cube looking structures (cube), while the epsom salt formed needle like crystals.
We looked at them with a magnifying glass and a microscope. Coolness!
Here are the epsom salt “needles”…
What have you been up to in your homeschool classroom? Any great experiments or projects to recommend?
All for God’s glory,
