Comparison

MATERIALS NEEDED:

  • o Sticks or ice cream sticks
  • o 2 large cups,
  • o Water
  • o Tub
  • o Scissors

PRESENTATION:

Gather the class and reiterate the subject of comparison. Explain that we are going to do an experiment on comparison.

On the table, lay two sticks side by side. They look identical in shape and size. Ask the children which stick is longer. They may say both are equal. Break one stick into two equal halves and lay them back to look like a full stick. Ask the children which stick is longer

They may say both are equal. Now push up the broken stick further up than the other. Ask the class which row is taller and see if they understand that both sticks are equal. This will help them understand displacement.

Next take two cups and fill them all the way to the top so that they are exactly equal. Put them both side by side. Ask the class which container has more quantity of water? Now pour one cup of water in a tub and remove the empty cup.

Now ask again which container has more quantity of water? (They are both still equal, only the containers which hold them are different but the quantity is the same)
