Hypothesis!!!!!

My Research!!! My research is that “Hubba Bubba is a brand of bubble gum originally produced by Wm. Wrigley Jr. Company, a subsidiary of Mars” said Kid rex. “Hubba Bubba is less sticky than other brands of bubble gum” said Kid rex. http://en.wikipedia.org/wiki/Hubba_Bubba

Materials - 3 types of bubblegum. - 2 piece of Trident gum - 2 piece of Extra gum -2 piece of Hubba-bubba gum - Toy room wall -my mouth to chew the gum - Outside wall

Procedure First I made the bubblegum signs. (Extra, Trident, Hubba Bubba) I put them outside and hung them on my house. Then I started to chew for exactly 1 min. I put them outside at 21.5 degrees. I put the Extra out at 10:18am and the Trident out at 10:23am and the Hubba bubba at 10:21am. I took a picture of each of them and then all of them together. Then I did the same exact thing inside at 70 degrees on my toy room wall. I put Extra out at 10:31am and Hubba bubba at 10:33am and my Trident at 10:36am. Finally all we have to do is wait to see what falls first.

Constant/variable Constant ~ amount of chewing Variables ~ outside ~location ~temp ~ Extra, Hubba Bubba, Trident

observations I observed that outside the gum has not changed only a little bit, only one gum fell and that was the Extra outside. The ones outside are coming off the most.. But inside the Hubba bubba and the Extra are peeling off the wall a little bit. Trident inside is totally stuck to the wall. So Extra and Hubba Bubba stick to the wall the shortest amount of time on both walls.

Conclusion My conclusion is that the Hubba-Bubba and the Extra stick to the wall the shortest amount of time because those are the two that feel of outside and peeled off a little bit inside. The gum outside was the one who stuck to the wall the shortest so we now know that gum sticks to the wall the shortest amount of time outside rather then inside!
