Most candy sinks in water, because sugar is denser than water. But some candy floats. Why?
One candy bar floats; one sinks.
What you need:
- Different kinds of candy, such as chocolates, sugar candy, 3 Musketeers bar, Kit Kat bar
- water
- Drop the candy in the water.
- Watch what happens: does it sink or float?
- If you have a 3 Musketeers bar, poke it to break the chocolate shell. Do you see bubbles escaping?

What a cool way to teach density and buoyancy with every day stuff:)
ReplyDeleteI will use this for the end of the year exam reviews. I'm always looking for new Density demos.
