We are continuing to learn a little more about science of the world around us. This week we continued with matter topic and focused on gases. We read Air is All Around You, but didn’t have a chance to do the main experiment in the book yet. We did talk a lot about properties of gases, and it was interesting to see what Anna understands empirically and what she doesn’t. For example, she gets that air takes space but she thought that air doesn’t have weight. I can see how it’s hard to see the weight of air, especially since balloons filled with air (and especially with helium) appear to have no weight. At least Anna could observe the power of a forced air – this simple experiment with a hair dryer still fascinates me as much as it fascinated her. It can also be performed with balloons, but I think that light plastic balls are more interesting since normally they don’t float at all.
I have some other air experiments planned, but Anna was more interested in spelling/math this past weekend than in science, and I decided to go with the flow.
