An activity that I would use in my classroom is the one based on hot and cold. We spend a lot of time in the infant classroom discussing the weather each day. I feel it is a good way to develop oral language and children like the routine of going to the window every morning to discuss the weather. For this lesson I would incorporate it into my theme of The Toy Shop in Aistear as we already do an experiment where we explore floating and sinking-Which toys will float on the top and which will sink to the bottom. We also then freeze the container with the toys in it and spend a lot of time discussing what will happen to the container when it goes in the freezer and how will we get the toys out of the block of ice again. I find this lesson really helps to develop children’s thinking around hot and cold, freezing and cooling and in turn develops their oral language. I like the idea in the lesson of the different scenarios where they must decide whether is it hot or cold. The movement to different areas of the classroom for this activity would be particularly great for junior infants. I think this could also be linked to Gaeilge and the theme of An Aimsir.
