I'm supposed to be teaching science to three groups of children. The older group 'gets' it...the younger kids don't get what I'm teaching at all. For example, I was trying to teach them about melting. I ask them what they see in front of them (a bowl of ice) and maybe one of them can tell me what it is (then I give them ice to hold). Then I ask where have you seen ice before? All blank stares. So I go into 'this is ice', 'this is water', this is hot water and the ice is going away...it's melting. All blank stares. I just had to change the lesson to Hot and Cold and had them touch/feel the water. It's like this with all of the lessons. I'm getting my lessons from two preschool science book/lessons/ideas. What do you do?
