Summer Science - AIG Properties of Matter Units 4 and 5

I respectfully ask that you not pin pictures of my children to Pinterest. Thank you!

Summer science is moving along. I feel like we're cramming but the youngling and the padawan are getting the big concepts. We'll definitely review during the regular school year.

For unit 4, we did a classification exercise,
broke water apart (electrolysis),
This was an experiment that actually worked for me and was really cool!

We skipped the experiments in lesson 18 but in lesson 19, we separated a mixture (OJ with lots of pulp),
We showed how oxygen is important for combustion,
Candle lit and burning with no trouble because of all the oxygen in the air.
The candle goes out quickly when it uses up all the oxygen trapped under the jar.
For sake of time we skipped Unit 4, Lesson 21 completely.

In Unit 5, we talked about how solvents and solutes work together to make a solution,
and measured the solubilites of various substances.

We read the experiments in lesson 23 but didn't do them.We did show how temperature relates to gas solubility and how "like dissolves like" (the whole wash your face with oil craze??) ;)
We skipped lesson 25 for sake of time and the making ice cream demonstration of lesson 26. (I forgot to buy the ingredients. Boo-hoo!)
We tackled the salt water experiment though, showing how salt affects the freezing and boiling points of water. Finally, we made our own seawater.
We didn't do the water treatment experiment for lesson 28; although, they read it. Unit 6 of the book (Food Chemistry) was also eliminated since it's not one of the topics studied in My Father's World 1850-Modern Times.

We finished up the book with lesson 34 (no experiments) and lesson 35. We used balloons, water, and a candle to show a representation of how God perfectly created our world to be perfectly habitable for the people, animals, and plants that He made.
Large balloon filled with air; small balloon filled with water.

The balloon filled with air popped almost immediately and put out the candle!

The balloon filled with water never popped. :)
"The earth is the Lord's, and everything in it. The world and all its people belong to Him." Psalm 24:1
