Sara and Tim have been working for weeks on their science fair projects. I am superbly happy that it is OVER! They learned a lot and enjoyed working on their projects, but boy did it take up a bunch of time. They both kept very detailed project journals on all that they learned during their research and experiments.
Sara learned about the mineral hardness scale and chose 10 minerals and rocks to test and make her scientific guess as to where they fell on the hardness scale.
Tim learned about the pH balance of 6 different liquids. He had a mason jar for each liquid and placed an egg in them. He tested to see the effect the liquids had on the eggs over a 3 day period, journaling about it several times a day. It was really quite interesting to watch what happened to the eggs.
Vinegar
Water, the egg got cracked during the experiment. oops!
Peroxide
Windex
Lemon Juice
Coke
This picture made Richard and I laugh. This girl was talking to Sara about her project, but it looks like Sara is trying to protect Laney from a bully that is ready to punch someone's lights out.
It was a good experience for both of them, but I think they, as well as me, are glad to be done with it and getting a bit more sleep.
