Related to our science topic this term of space, both year 5 classes have created experiments using balloon power!
Initially, the plan was to investigate whether a balloon with a larger straw (exhaust) attached to it would travel further than one with a smaller straw, though in the end a completely different result was proven, as Lola will now explain:
The string we used in the first place was wool so it was fragile and had too much friction, but when we used a different kind of string that Mr Wise gave us it worked perfectly well and traveled over a metre each time, as it had less friction.
Thank you Lola! Sometimes we enter science experiments expecting one thing and we then unexpectedly out something else entirely!
