Light and Sound

Division 11 have been learning about light and sound. We learned what makes light and how sounds are made.  The kids all demonstrated a sense of wonder as we explored with different materials and activities!

What happens when light shines on things?

We learned that transparent objects allow all or most light to pass through them; translucent objects allow some light to pass through them; opaque objects do not allow light to pass through them; and some objects reflect light

 

What makes a shadow?

We learned shadows are made by blocking light.  A shadow is created when an opaque object is placed in front of a light source and stops the light from passing through.

 

How does light make a rainbow?

Rainbows are made when sunlight shines through the water. As a result, light reflects off the water droplets, bends and splits. When sunlight shines through the water droplets, it splits into seven colours.

 

How are sounds made?

Sound is made up of vibrations, or sound waves, that we can hear. These sound waves are formed by objects vibrating or shaking back and forth.
