Last week we continued our review of senses by learning more about how our ears work. We read a couple of books from Let’s Read and Find Out series, and played online listening games on Exploratorium website. We actually got a membership to Exploratorium for Christmas but didn’t get a chance to go there yet.
We also conducted a couple of experiments to see how our ears work. One of them was identifying common sounds without looking, and another one was “model eardrum”. We stretched a plastic wrap around a big bowl and placed rice grain on the wrap. Then Anna banged on the cookie sheet/played guitar next to the “eardrum” and we could see rice grains move. She was pretty fascinated to “see” sound. It also made me appreciate sensitivity of our ears, since only very loud noises could make rice grains vibrate.
I found a few videos from Human Body for Children series in our library and we were very pleased with their quality. The videos are less than 30 minutes long, but All About Senses was packed with information and even included some simple and fun experiments. The webpage I referenced above also contains a worksheet with experiments to try and a teacher guide. We might try some of the smell and touch experiments this week for our next topic.
