Let&#8217;s think about which container holds the most water? Measure how much water the children think can fit in the largest container.<\/p>\n<p>Try and see if this amount of water can fit in any other container. Measure how much water the children think can fit in the smallest container. How many times does this amount of water fit in the largest container to fill it?<\/p>\n<p>What about other containers? Consider if there are any containers that are different in shape but can hold the same amount of water. For example, fill two containers to be examined with water to the brim. Then a measuring glass is taken, the water from another container is poured into it and the amount is read. Empty the measuring container, pour water from the remaining container into the measuring container and read the amount. Compare these numbers.<\/p>\n<h2>Step 3: Why<\/h2>\n<p>The amount of water can be used to observe the concept of volume. Volume is all the space left inside the edges of the container. The volume can be very small, even if the container is large. On the other hand, the volume can be large, even if the container is shallow.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What do the concepts mean more, less and as much?
