Today, I started by giving them some information about energy in collisions. During the investigations, one student talked about the energy possibly becoming sound. I decided that today would be a good day to let them know that in a collision, some energy is usually transferred to the surrounding air. As a result, the air gets heated and sound is produced. (From NGSS PS3.B)
The boys wrote a paragraph based on these instructions:
Write a paragraph about your investigation. Describe your investigation. What were the results? How much do you trust the results and why? Try to explain your results using energy ideas. What questions do you have now?
After the students wrote their paragraphs, they met in a scientists' circle to share their results and ask each other questions.
Two questions we want to investigate now are:
Do heavier objects add more energy?
If you only do two balls, will it last even longer?
