Thanks for this experiment. It was fun and thoroughly engaging. I don't know how it will be received in the Pre-K classroom, but I think I will try. Maybe just using it during the Human Body lessons would be best. I think simply talking about how we are all different because of something in our body called DNA would work. The concept of being different could be illustrated at the gross level by how we all look alike and at the finer level by painting our fingertips. Children could use the magnifier to look at the different patterns of the each other's fingertips. Then once we all agree we are different and it's because of DNA (DNA makes you what you are), I could ask if they want to see some DNA (DNA that makes a strawberry be a strawberry). There we go..... OF course, cross-curricular learning, and if you want it to stick, use a song, I would have to make a song about DNA.

TO the tune of Three Blind Mice:

DNA, DNA it makes me, me

It makes you, you

DNA has all the say

DNA makes me look this way

DNA,DNA

PS Is the DNA for each strawberry the same?
