Lizzie's project was done at home -- Recently she learned how to read braille at a Girl Scout meeting. She thought it was so hard to feel the dots, and then wondered whether blind people had better senses since they could not see. So, she decided to do her science fair project based on that observation. She ran a series of experiments (with us) to see how well our senses worked when we could see and when we were blindfolded. We had to taste 5 different flavored candies, smell 5 different scented markers, listen to the radio at different very-low volumes, and tell how many pins we were pressing on our arm. Her results -- our sense of touch, taste, and smell were NOT as good when we were blindfolded, but our hearing improved when we were blindfolded.
As a 6th grader, Carolyn does her science fair project completely at school with a partner (Ava), working with their science teacher. She came up with the topic and ran the experiment on her own. She wanted to learn more about electrolysis - what happens when you add electricity to water and how you split water molecules into its elements. Her hypothesis was that they would see more electrolysis in salt water versus distilled water. She must have done a great job presenting the chemistry because she was awarded a first-place ribbon at her school's science fair, and is now going on to the next level next week.
