This science project was done by Jose, who is a student at Texas School for the Blind and Visually Impaired (TSBVI).
Which soda will cause the biggest explosion when mentos is added? I will test Diet Pepsi, Sam’s Choice, Pepsi, Sprite, and Coke.
My hypothesis is that the Diet Pepsi will explode the most.
Sam’s Choice Soda
Find a big lawn.
Unroll the package of Mentos.
Using the tool, place 2 Mentos into the tube of the tool.
Take the soda in your left hand with your right hand slowly twist the cap of the soda so that most of the gas will stay in the bottle.
Empty the Mentos into the Coke.
Repeat this procedure for each type of soda.
Measure how much soda remains in the bottle.
Analyze the data: the more soda left in the bottle, the less the explosion.
Diet Pepsi: 1,000 mL
Sam’s Choice: 1,305 mL
Pepsi : 1,275 mL
Sprite: 1,630 mL
Coke: 1,130 mL
Diet Pepsi: 2,000 – 1,000 mL = 1,000 mL
Sam’s Choice: 2,000-1,305 mL = 695 mL
Pepsi: 2,000mL- 1,275 mL = 725 mL
Sprite: 2,000 mL – 1,630 mL = 370 mL
Coke: 2,000 mL – 1,130 mL = 870 mL
The Diet Pepsi exploded the most.
My hypothesis was correct because the Diet Pepsi exploded the most.
I considered comparing different types of candies instead of different types of sodas.
Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.
