We're doing air and water transportation this week, and I wanted to do a science "experiment" where we could use OUR air to see how far we can blow cotton balls with or without a straw. I also have mini koosh balls I can use. I'm trying to figure out a good way that we can record what we find out... either an individual sheet for each kid or a class sheet... this will be in several small groups of 3-4 kids each.

Ideas?

My immediate thought was a posterboard with "How Many Cottonballs?" at the top... then to show the distance by the number of cottonballs. (For example: Maria blew her cottonball 4 cottonball widths away so she gets 4 cotton balls, but Bobby got 2 because his measurement was two cotton balls way....)

I'll keep thinking though, that was just my first immediate reaction to the post.

Thanks, Ms. Ann. That helps me get started. I want something that will make sense to my kids, but also something that will be useful.

How about as a way to introduce number identification you could have a number line down and they blow their cotton ball along the number line and count to the number that it is closest to. You could also use this to record the results. Jonny blew his cotton ball to the number 2 with his straw and the number 4 without, etc.

can you use a sheet of graph paper, draw a "start line" then see how many squares the cotton can be blown with out a straw then with. you could graph the numbers if you want.
