Science!

Yesterday my class had science, In science we were learning about sounds and about how we can see sound. Sound is a source of something we can hear and sometimes feel, We hear sound because it travels in waves and travels through air and eventually reaches your ear.We made these phones with paper cups and string, also we made these dancing sprinkles with hums. We tried to make the cups shorter or with more knots.I learnt that we can hear like a microphone with the phones. Here are some pictures
