CO2 rocket experiment by John Hayden https://padlet.com/j_hayden/4ixqa72xuby By John hayden Period 7 en-us 2018-03-20 20:46:27 UTC 2024-11-26 12:50:37 UTC hello@padlet.com alka seltzer rocket experiment j_hayden https://padlet.com/j_hayden/4ixqa72xuby/wish/244275339 The alka seltzer experiment is an experiment that we put alka seltzer in a little cup and snap the lid on and wait for a chemical reaction.the chemical reaction is when the cap pops off because of the fizz from the alka seltzer creates a expolishion my variables that i will only use 1 4th of the water and my partners variable  is using 3 4ths the needed water the normal amount of water is 2 4ths but she will be doing 3 4ths and i will be doing 1 4th my hypothises is that the rocket will fly shorter because that's less water for the alka seltzer to fizz in and for my partners i think it will fly farther because that's more water and the same size and amount of alka seltzer but i think it will fly farther because 3 4ths water is much more than 1 4th and i think there will be less room for alka seltzer but the water will make the alka seltzer fizz more leading to a bigger expolishion witch means for preesure wich means the more water you add the farther the rocket will go. so that is what i think will happen if my partner puts 3 4ths water and i put 1 4th water that the rocket will fly farther with more  water and with less water it would fly closer to you then to the other rocket so that's what i think will happen but i'm not sure because we still have to do the exeperment ourselves for safety we need goggles and need to follow direction as well as to be sure to point the rocket away from your face.]]> 2018-03-20 20:47:40 UTC https://padlet.com/j_hayden/4ixqa72xuby/wish/244275339 Picture j_hayden https://padlet.com/j_hayden/4ixqa72xuby/wish/244278957 2018-03-20 20:56:51 UTC https://padlet.com/j_hayden/4ixqa72xuby/wish/244278957 3rd picture j_hayden https://padlet.com/j_hayden/4ixqa72xuby/wish/244280518 Not my rocket!!!]]> 2018-03-20 21:01:53 UTC https://padlet.com/j_hayden/4ixqa72xuby/wish/244280518 Secound picture j_hayden https://padlet.com/j_hayden/4ixqa72xuby/wish/244281970 2018-03-20 21:06:16 UTC https://padlet.com/j_hayden/4ixqa72xuby/wish/244281970 Trials j_hayden https://padlet.com/j_hayden/4ixqa72xuby/wish/244283007 1. 5.2
