If your kid(s )already know Genes and importance of Genetics, I would highly recommend a cool DNA extraction experiment at the following site:
He read it once, made a list of things needed from store, he biked <2 miles, I walked> to do the shopping and was able to do the follow steps all by himself. Only ticky part was closing the ziplock bag. You can use a clean plastic and use a rubber band to seal it.
Instead of strawberries you can use some other fruits like grapes, apple, vegetables like tomato. Sid enjoyed doing this experiment, hope your kids like it too!
