Bone and Skin – Science Experiment
After studying about bones, Kabir did the puzzle showing all the bones on a human body.
Then we bought a drumstick to perform a rubbery chicken bone experiment. Kabir felt how hard and strong it was; then he put it in vinegar for 3 days to observe the effect of vinegar on bone. As we had read about ligaments, he saw and felt it on the drumstick. The bone didn’t become rubbery but it did become fragile and it snapped in two very easily. I didn’t lose the opportunity to tell him the importance of calcium for our bones.
Then Kabir made a model of his arm using paper towel rolls. We added balloons to represent the muscle and we observed how muscles work when we bend our arms.
Then we studied about skin and we performed a simple experiment to understand how skin cools the body. At first, I rubbed a cotton ball dipped in ice water on Kabir’s wrist and then I rubbed the cotton ball soaked in rubbing alcohol. Kabir felt more cool with ice water. Then I rubbed his wrist with cotton ball soaked in lukewarm tap water. He felt his skin cooler with the rubbing alcohol this time.
