Elementary Chemistry and Physics Experiments

We’ve been loving science with Apologia Exploring Creation with Chemistry and Physics .

Science Experiment #1: Separating a Homogeneous Mixture

• 4 Crayola markers (purple, brown, black, green)
• 4 pieces white chalk
• 4 plastic cups
• water

Draw a ring of color around each chalk stick with a different color marker on each chalk.

Set each chalk stick in a cup of water (no more than half-full).

The water will creep up the chalk. It’s pretty cool!

Tori draws her ring of color on a piece of chalk.

Alex did super following direction and drawing his ring.

Kate concentrated to get her circle just right.

We set the chalk sticks in cups.

After I poured in some water, Alex wanted something immediate and amazing to happen. He was kinda disappointed.

After the water got to the ring, it bled the color. Brown was the neatest, separating all the colors.

Here is the completed experiment.

Experiment #2: Making Butter from Cream

Fill a small jar half-full with whole cream.

And shake.

until it become mostly solid. You can drain the buttermilk or use it (there’s very little). Add a little salt and refrigerate to solidify more.

The kids loved having *their* very own butter!

So of course, I made biscuits for dinner. For the butter.

For science.

Tori loves biscuits.

Kate just recently began liking butter. So happy she’s normal.

What fun science have you done lately?
