My grandaughter Alisa had to do a science project for school and asked me if I could help her. Well, sure I said until I heard what it was about. Now my husband is a retired school teacher and taught in math and science. Two of my worst subjects. Alisa project was on science. Well, I did alot of checking on the net and came up with the whole idea!!! She needed to pick a element so she picked calcium. Wow did I learn alot more than I knew when we first started. There are 20 negative electrons, 20 positive protons and 20 positive neutrons. There is 4 energy levels 1st is 2electrons, 2nd is 8electrons, 3rd is 8electrons, and 4th is 2electrons. So the Atomic # of calcium is 20. BINGO...Did you all understand that? I do now and as we put the project together my son got involved and said she needed a stand for it to be on. This stand had her project tied with fishing string and looked as if it were floating. Tom also helped us figure out how we would hook the different levels together. I think with alot of helping hands this project was the BOMB. Alisa got a A on this project. Way to go!!!! I must admit it started out to be a big stress and in the end a fun and learning experience.
