We read The Bubble Factory by Tomie dePaulo. We discussed whether or not you could actually make different colored and shaped bubbles.
I was surprised Shayla wanted to make bubbles because we have done it often. We made our own mixture using this recipe:
2 c. water
10 drops glycerine (can substitute corn syrup)
3 TBS dish soap
We tried using several different bubble wands and even making our own wands. The result was always a round bubble.
*I did learn something interesting at the library this summer, you can touch a bubble and it will not break - if you have wet hands!
Homemade Recycled Paper.
Again, we have done this activity in the past, but it was encouraging to see Shayla participating more. Like this time, she had no problem tearing the newspaper into pieces.
- Tear one page of newspaper into small pieces. Put the paper into a blender with water. Let it sit for about an hour.
- Blend until the paper becomes soft and mushy. It is now known as pulp.
- Mix 2 TBS starch (corn starch or liquid laundry starch works) in one cup water. Add to the pulp and blend again. The starch helps to make the paper pulp stronger (but it does work if you happen to forget this step :)
- Spread towel and newspaper on table.
- Let dry overnight.
We discussed chemical reactions (like baking soda and vinegar). Then we tried this experiment. I must admit, it worked some, but not like I had hoped.
- 5 TBS pure laundry soap. I used Arm & Hammer Washing soda (maybe this was the wrong thing?)
- 4 TBS salt. I used sea salt. Was it supposed to be Morton's?
- 1 quart jar
- large spoon for stirring
- glass measuring cup
In another cup add salt to one cup of water and stir until dissolved (as much as possible).
Pour the soap solution into jar, followed by the salt solution. Mix well.
You should see the soap harden and turn into a ball right away. If you let the mixture stand still for a few minutes, the soap will go the top and the bottom will stay clear.
We did not get a ball. We got lots of tiny balls.
Experiment 3: Rub two balloons on hair, then try to stick the two balloons together. You should feel a slight friction between the two balloons.
