My learners have been learning about matter, the 3 stages of, and how one stage can change into another.
Originally, we filled 2 containers with water, one covered, and one not. Then, we filled a 3rd container with ice. We have been observing these containers over the course of this week. The covered one has not changed. The ice one melt and really went down in the container. The plain uncovered water one just went down. The children put together that the ice one melted and went down because ice takes up more room than water. The plain uncovered water one went down because of evaporation. Lastly, the covered one hasn’t changed at all because it can’t evaporate past the plastic covering it. Then, because of the snow, we were able to add a 4th container full of snow packed to the top. Well, in 4 hours, the snowy one went down to half the height of the container. The students think that it will shrink more as it turns into water completely and then eventually will evaporate altogether.
Geniuses…all of them!
The one covered in plastic, that hasn’t moved. The one that was just water, which has evaporated a little.
The one packed with snow, that is 1/2 its size. The one that had ice to the top to start and has now
really gone down.
