Week 7, Day 5 in ECC - Science Experiment Day

Light and independent Friday - the day to catch up on science experiments.

We started with Pledge, Awana verses, and then did our vocabulary pages. I sketched, Rabbit wrote and colored. After Spanish, I did a little verse review with the boys, and then told them they were going to help with our experiments.

We did drops on the spoons, to see how the water kind of bulges and holds together. Then we floated the paper clip. That was cool. (I showed that one to Dad when he got home - he didn't think it would work.) Here is a picture of the paperclip floating in a glass of water:

Here is what the "helper" paperclip looks like:

It was a bigger paperclip than the one in the water. I laid the smaller one on this one, and then slowly lowered the paperclip into the water, trying to keep it level.

After that, we went outside with a board, and did our valleys and mountains and poured water and watched the path the water took. The boys loved helping put dirt on the board - that's what boys are good for. I had to kind of prompt Rabbit with some questions to get her to think about what the water was doing. Here is the water rushing down our landscape:

Then, the last experiment was about friction. The experiment said to use a board, but I didn't think it would be easy to tie a rope around a board. So, we borrowed one of Dad's cordless drill cases and two 5-pound weights. We tied the rope around the handle and then put the weights on the case. First Rabbit tried to drag it on the carpet, but it was tough. Then, we dragged it on the linoleum, and it was easy. Then I let each of the boys try. They could barely pull the "sled" on the carpet, but could easily pull it on the linoleum. I talked a little about friction, but not much. I decided the best thing was to let them experience it. These two picture show the "sled" on carpet and the floor:

After lunch, Rabbit did her Gamma Unit Test I - and she got a 100%! Hooray! She knew her math facts very well. She did miss three words in spelling (and the attitude came back again for spelling). But, after she was done, we reviewed all the words missed for the week to get ready for Monday. Then we did reading and poetry and were done.
