This week we spent some time considering capacity; identifying containers as full or empty and comparing containers to decide which would hold more or less water. We began with a whole group session. I showed the children three different containers designed to drink from; a flask, a bottle and a mug, and asked them which they felt I would be better off using if I were very, very thirsty. There were different ideas about which one might hold the most water. We decided to test the containers to see which had the largest capacity. Using a small plastic cup, we counted how many cups of water could fit into each container, and used number cards to mark each one so we would remember and be able to compare afterwards. We discovered that the flask held five cups of water, the bottle held two and a half, and the mug held one and a half. We talked about the numbers, and decided that five was the biggest number, which meant that the flask could hold the most water, in other words that it had the biggest capacity. Following the group investigation, the children were given time to explore and investigate the capacity of a variety of different containers, using water to fill and empty cups, cylinders and pots. It was fun guessing how many cups of water it might take to fill each container before checking, and especially fun filling containers to overflowing. Experimenting with capacity is something that can easily be incorporated into bathtimes at home, or in the kitchen when making and pouring drinks, for example.
