As we continue our study of sound waves, students are experimenting also with light waves and learning how light travels. INQUIRE with your child how light travels and what kinds of materials allow light to travel through. Use the words - transparent, translucent, and opaque to discuss this with them. Which material does NOT allow light to travel through?
Towards the end of the week, students are going to be making telephones with plastic cups and string to experiment with how sound waves travel.
