In the afternoon, students learned more about sound and vibration with paper cup telephones. They also experienced how sound moves differently through solids and gases by tapping on their desks. The students were able to hear how much louder the tapping sound is when their ears are pressed against the desks.
The students were finally able to play their board games today after working hard on them over several days this week. The class was very excited and they were able to see how different groups made different kinds of games.
