We go to a fabulous co-op once a week at a Catholic church near us. There is a wide variety of classes to choose from including science. In just the last few weeks PJ has gotten a literal hands study of the heart (thank you Miss Moo), the brain (a shout out to the sheep) and the lungs. This is what they made last week to see how the diaphragm pushes up gently as the lungs expand.
Do you think a 5 year old boy likes this stuff? You bet your sweet bippy he does!
