FC: My Rocket Book By Travis B.
1: Rosenstein's tips: | Intro. In the past few weeks we've been working on building rockets but first we tested out a few things including What solvent we want to use? oil? NOOOOOOOO! Water? maybe, it dissolved pretty fast Vinegar? definitely! it was speedy Than we decided if we wanted a crushed or solid tablet After, we finally decided whether we wanted hot, cold, or room temp. water
2: Rosenstein's Tips: | Lift:The force in which the rocket or plane is lifted Gravity:The force in which the plane is weighed down Thrust:The force in which moves the plane or rocket forward Drag:The force in which holds the plane/rocket back and slows it down Newton's 3rd law: the truth that when ever one thing goes one way, something else has to be going the other.
3: My Group's Rockets | 1.)Our first rocket we used only construction paper because cardboard is to heavy and would have to much gravity We also used room temp. vinegar filled half full, that was a good choice, it took 12s to dissolve, enough to get the cap on it went up 4 ft. in the air, thats pretty good.One way it wasn't that great is because we thought the cap wasn't snapped on so we picked it up and it fired in our hands as we were holding it, we thought it was because we figured it wouldn't because we had paper in the way of it. 2.) Our next and last rocket was better, It went 5 ft. in the air so it was only better by 1 foot difference, but it's still an improvement! We still only used construction paper because we saw some others with it and they were fails. We used hot water because room water or cold vinegar wouldn't have a big enough blast and so we figured hot vinegar wouldn't let us get the cap on in time.
4: The difference between the best and the worst The best group went up to about 12 FT.! Unlike our group they used very little construction paper and made their whole rocket's nose just as big if not bigger than the body with only 2, 1 layer fins while ours were 4,2 layered fins (not such a great idea).
5: Some groups did things a little differently and wasn't such a good idea such as:adding the slitest bit of cardboard, made their bodies to large, or like my group making the wings thick thinking the wind would be able to ruin them, etc.
6: Sources of Error: wind blows over rocket cap doesn't close because of paper in the way crumpled paper to create more wind resistance(can't uncrumble it)
7: Control:What size and shape of the rocket Dependent:how quickly it took to dissolve, and how high the rocket flew Independent:The solvent and it's temp., what sized tablet (I don't know, I might have the control wrong and the dependent and independent backwards)
