Anyone doing science fairs? This is the second science fair for my son (age 11) and the first for my daughter (age 6). My son originally wanted to determine the effect of positive and negative attention on mold growth. He was going to talk nice to one mold colony, talk mean to another colony, and ignore the control group. Then he decided that he couldn’t bear being mean. Next he decided that he would see if magnetism would have any effect on mold growth. He postulated that most living things have iron, so magnetism should have an effect. Now of course we are having trouble growing mold. Also our science fair prohibits experiments using mold but it isn’t deterring my son from continuing his project. Thirdly he is also experimenting with the effects of magnetism on growing bean and radish seeds. This project is not as interesting but will meet science fair approval. My daughter wanted to figure out the smallest thing in the universe. Of course we can’t do that so she is settling on “mixing things.” So I had her make predictions about which juice would produce the most gas when mixed with baking soda. Her experiment was too easy so we might think of ways to add another dimension to it before the fair. Anyone else out there with science fair mania in their home?
