The strength of air

This second part to the Floating in Air unit is all about air pressure and the strength it gives us. The activities build on the lesson " Amazing Air", allowing the students to see what air can do. The basic concept that is examined through all of the activities is how strong air can be. The next step after this set of activities (The strength of Air) is to look at how we need air, not only to breath and live but also in everything we do.
You will need lots of balloons, funnels, balls and other things, all of which should be fairly easy to get. The students will have a written assessment with these activities, to allow you a more formal form of assessment, while informal assessment is always there. The written assessments were created with three levels - cubs, mama bear and papa bear. I encourage the students that they have to do two - the level they are really comfortable and the next level up. (ex. cub and mama bear or mama bear and papa bear. The logic behind this to not only assessment the students but to also allow them to have some control over their assessments.
