Sound - African drums
The grade 4 students created models of an ear using a balloon and a sturdy cardboard roll from a carpet store which we used to explore some of the properties of sound. The students in Mr. Makki's class turned these models into African drums. We were able to explore sound vibrations, and creating different tones by hitting the drums with a different part of our hand or striking a different part of the drum.
Spectroscopes
Scientists use this tool to separate white light in to a spectrum, or rainbow, of colours. We made our own as we continue to explore the amazing properties of light!
Refraction
Refraction is the bending of light.
Exploring Properties of Sound
Using hands-on activity stations students explored various properties of sound:
1. String Telephone - sound travels
2. Water sounds - explore sound as vibration and visually see vibrations in the water
3. Elastic Band guitar - explore frequency and pitch of sounds using elastic bands of different thicknesses
4. Make a musical instrument - students make their own pan flute out of plastic straws
5. Match that sound - students explore 5 different coloured cannisters containing different materials. Using their hearing and inquiry skills they make predictions about what they think are inside the different cannisters

Water Xylophones
Students used beakers of the same size and shape but put different amounts of liquid in each. They used a plastic spoon to tap the sides of the beaker to hear how the amount of water changed the pitch of the sound made. They noticed that higher water levels resulted in a lower pitch, and lower water levels resulted in a higher pitch.
