Grade 4 students! If you enjoyed our experiments in class this week and would like to explore more fun things to do with sounds. I'd like you to check out these cool websites Changing Sounds and Play Music to test out different musical instruments.
This week in Grade 4 Science: we learned about the properties of Sound.
We discussed how sound travels, showed that vibrations make sound, we recognized that vibrations can be changed to alter the pitch of a sound.
We conducted experiments that allowed us to observe that sound travels through different states of matter: solids/liquids/gases(air).
We learned the following vocabulary words: vibration, vocal cords, larynx, sound wave, pitch and frequency.
