Grade 2 light and sound
How light travels and makes shadows and colours, and how sound is made and heard. Here is what we have for Grade 2.
Lessons
Light and Shadows
Why does my shadow follow me, and why is it so long in the morning? Young scientists chase their shadows, track the Sun across the day and test which things let light through.
Sound: Can You See a Sound?
Can you see a sound? Young scientists make rice dance on a drum, talk through a string telephone and build a rubber-band guitar to find out that every sound starts with something shaking.
Earth and Sky at Home
Make a rainbow on the kitchen floor, grow crystals on a windowsill and build a cloud in a jar. Three classic home experiments that actually work, with the real science explained for grown-ups.
