Last week the girls had 2 science fairs to attend. Since they were only one day apart, they were able to use the same project for each. Emily had other things going on, so for the first time, she missed doing the science fair.
Elizabeth did her project on electricity. She made several batteries, out of pennies and foil, apples and potatoes and lemons, that powered a clock. Then, she made a windmill that ran an LED light bulb.
Rebecca did hers as a research project and studied the solar system in great detail. She made a replica of the system to accompany her display board.
