10. Which One is Heavier?
This activity, which is perfect for toddlers, only takes a few minutes and it is very easy to do. Make a balance scale out of a coat hanger of something similar. Then take 2 objects that you can find around the house and put them on the scale to see which one is heavier. Children find it fun and they can be amazed how some small things can be heavier than others which are much bigger.
