balloon madness

last week in science,  we were learning about ballon madness make's the balloon travel  up and down 

how it works

the gravity on the balloon made it travel up if was smaller would travel it faster?

the big it is slower it go's 

 

i was learning about balloon madness  

i found it easy to  to make the balloon travel up 

i found it hard to  to see how if smaller travel faster 

i really enjoyed working with buddy  

next time i will  see if smaller if make faster
