Today, Jonathan was helped to understand basic principles about the properties of matter. This was initially achieved by performing a hands-on classroom experiment to illustrate the property of wind. We made a wind gauge using a sharpened pencil, two small paper cups, a drinking straw, a pin, and tape. We then went outside with our wind gauge to check to see if it would spin. We discovered that air makes the wind gauge spin; Jonathan noted that there was very little air or wind current today after observing that the wind gauge remained still. However, we subsequently used a fan and Jonathan noted how quickly the cups spun after being exposed to the air current generated by the fan. The vocabulary term learned today was 'anemometer,' which is an instrument used to measure the speed of the wind, direction , or any current of gas. Jonathan seemed to greatly enjoy this hands-on activity, and he hung the wind gauge in his room.
