Weights and Measurements

Last week we looked at weights and measurements. We compared how a one kilogram free weight and a one kilogram bag of pasta looks and feels different. Visually we thought that the free weight would be heavier because of what it is made of! Looking around the house we found lots of different items and compared the weight and feel of them.

M y son, even though he is only four loves to exercise and will do various workouts most days (of his own design or from my husbands grand collection). He is very interested in the different weights we have around the house and it is a great way to get home to add up and understand balancing.

We decided, to make a balance scale and use the household weights to see how heavy the kids were. We gathered together:

  • a long leftover floorboard
  • a breeze block
  • a brick
  • a variety of weights
  • two children

The idea is that you put the breeze block on the ground, add the small brick on its side (to make a pivot), and then add the floorboard on (it needs to be in the middle). Then add some weights and a child!

Word of caution! As the board is not fixed you cannot add to one side without adding to the other side at the same time or it will fall!

If you are using children you need to lift them, and hold them until there is a comparable weight on the other side!

Carefully getting our equipment together we slowly added a child on one side and then loaded up with weights until the floorboard was balanced. It was a bit precarious but both of the kids loved it.
