I am beginning to plan a unit on weather that I will be teaching in a 4th grade class that I will be taking over for a maternity leave position in December. I did some weather lessons during my student teaching in a 4th grade, and I have the curriculum guide, but as I've stated in previous posts, I really want the kids to enjoy my time there and I'm hoping to impress the administration enough to be offered a permanent position for next year (they already know of 2 openings!). Some of the ideas that I have are: -Water cycle in a baggie -Water in a cup (shows that air has mass even though we can't see it) -Tornado in a bottle There are plenty of other ideas in the curriculum guide, but this is as far as I've gotten as of now. Does anyone have any ideas for hands-on activities that you like to do when teaching weather? Thanks in advance!
