Science 9 – Students continued with their circuits. Today’s results were really surprising to everyone. By adding another bulb in parallel, the bulbs didn’t go dimmer! This was a shock to everyone. I tried to help them to understand what was happening by using an analogy of blowing through one small straw vs blowing through three small straws at once. Unfortunately I didn’t actually have the straws and many kids thought three small straws would be harder to blow through.
Note to self: have a box of stir stick straws in class next year.
