Katrina's Science Experiment

Here Katrina is measuring the water to put the hot can into.
She is learning about air pressure.

Here is the can with about a centimeter of water in it, being
heated on the stove burner. Once the steam came out in a steady stream,
she used tongs and inverted the can into the pan of water.
Then the can made a loud POP and was dented in!!
It was really fun to do. She said she didn't understand it, so we did the experiment that used a candle, jar, colored water. I forgot to take pictures of that one. For those who want to try it at home, you take a shallow dish and add about an inch of water, add a few drops of food coloring to it. Put a candle in the middle of the water and light it. Put a glass jar over the candle and watch it go out and the water goes up inside the jar.
Because of the air pressure being greater outside than inside, the water goes in the jar.

Finally a picture of her cast. We go back to the doctors on the 25th to see if she can start walking without the crutches. He said that it was healing very nicely.

We had a truly great week of homeschooling and hoping that it will continue.
Dylan starts his guitar lessons tomorrow and is very excieted about it.

I must go and read to them and hopefully get them asleep before 11!!!!
God Bless you all!!
