Science 10 MYP Popcorn Lab

Experimental Design We’ve been hired by Mr. Redenbacher to find a quick and accurate way to find the number of popcorn kernels in a bag of popcorn kernels without having to count them individually. We can apply our knowledge of solving problems involving the mole to find the number of popcorn kernels in the bag. Variables: Manipulated: Weight of Kernels. Controlled: Plastic Bag, Scale. Responding: The Weight of the kernels in grams, the number of kernels in the bag, the weight of the plastic bag in grams.

Prediction/Hypothesis I think that for us to accurately find the number of kernels in the bag, we will need to simulate calculations involving the mole. I think that this should be done by
Use the answer from step 5 and multiply by Avogadro’s number (6.02 x 1023) in order to find the approximate number of “atoms” (popcorn kernels). When all calculations are completed, return all materials properly.

Evidence/Observations

Weight
Plastic Bag Full of Popcorn Kernels Empty Plastic Bag Weight of 1 Popcorn Kernel
354.44g 2.76g 0.19g

"Weight of Plastic Bag Full of Popcorn Kernels "-" Weight of Plastic Bag = Weight of Popcorn Kernels "
"
" " = 354.44g "-" 2.76g = 351.68g"

Use: n (number of moles/kernels) =" " (m (mass in grams))/(M (molar mass in g/mol) )
"
" "# of Kernels = " 351.68g/0.19g
# of Kernels=1850.95=1851 Kernels

Analysis As you went through the lab you used various steps of the design cycle to solve your problem. Which did you see? How did they bring you closer to your final solution? At first, we had the investigated the problem and soon found a solution to it. We used our background knowledge of having to apply a scientific concept in order to help solve the problem. At first we had done some trials to see which of the knowledge we would have had to incorporate into the popcorn kernel problem, then we discussed on what needed to be done in order to calculate the approximate amount of kernels in the plastic bag. As our plan grew, we had decided to go through with it and we saw that it worked out well. This brought us to our final solution because the more we asked questions and discussed it as a group we were
