This guided experiment was helpful because everyone was going the same thing so I could have an easier time asking for help compared to everyone else going all there one things that need help. I can also ask for help from the people I'm working with. But mostly it was fun to be with people that had the same interest and asking lots of questions that the others can relate or comment on with me.
We have made helium as dense as air which is really cool. How we did that was making the balloon the same weight as the air. But how did we do that? well first needed to find the weight of the balloon its self and the V(volume)-sphere of the balloon. then using the weight of air, we calculated the weight of air in the balloon(just hypothetical) V.S the weight of helium to get the weight of the helium in the balloon. then we started to put tap on the balloon and we got so close to the weight. We had it at where it would float, but it would sink if left it alone. When the other teacher hugged the balloon to make it warmer it started to move up or stay still. I thought this was because the colder and object the more dense a object becomes. So the warmer the less dense which means floating! Also to make us laugh the teacher breathed it the helium so his voice got really high. Then I wondered why that was so I asked and then he said it was because it was light than air. Then another thought, if the light the gas the high your voice,what would heaver ones do, we watched a video on a new broadcast of where that we playing with a heavy gas and it mad there voice really low. It was so cool and funny at the same time. I wish I could have tired it.
