Hearing. It's amazing how sounds passes through the ear canal to the eardrum to the 3 small bones to the cochlea and how our brains can translate that vibration into words or sounds. We didn't do any experiments with hearing today, but here are the books we added to our lapbook.
Can You Hear Me Now? states amazing facts about our ears. We read in the Usborne book what decibals different sounds are. Then we made this accordion book showing the different parts of the ear.
I wanted to make sure we had covered all 5 senses in this study (skin-touch, eyes-sight, ears-hearing). I didn't have anything planned for smell. There isn't much to study about the nose except that there are smell receptors that send messages to the brain about what we smell. I did, however, find an experiment to try about how our tastes are affected by our smell. I cut into small pieces some potato and some apple. The boys plugged their noses and tasted the potato. Because the texture is about the same in both, they shouldn't have been able to tell the difference between the two. (I tried it before they did, and I could taste the difference, but decided to let them try it anyway.) They both made a face and exclaimed "What is this?!?" Then I let them try the apple. That also they could taste, but it left a better taste in their mouth. :)
We went ahead and started the taste sense today with a study of teeth.
