How do you find the area of science that covers your project? You guessed it, network with your mentors, parents, and teachers. And by the way, networking is something many adults don't expect students to be very good at, so you can probably surprise them by doing a good job at it! The very best networkers, of course, enjoy the spoils of victory. In other words, they get what they want more quickly, efficiently, and smoothly.
If you are doing an engineering or programming project that involves designing or inventing a new device, procedure, computer program, or algorithm, then be sure to check out the Science Buddies resource The Engineering Design Process. You should have some special questions in your background research plan.
Ideally, the time would be the same for each, but as you found out that won 8767 t work. So I recommend either popping for the length of time recommended on the bag/box (so making each according to instructions) OR (if that info not available) then yes, pick a standard time that you will stop all bags at (like you said above, as soon as the popping to drops to less than # per # (. 8 pops per 5 seconds or similar whatever the average person making popcorn might do) as long as you do it the same for each, then that variable is normalized (. taken care of).
You can measure the effectiveness of popping in several ways: number of kernels popped, number of kernels that did not pop, percentage of popped (# popped divided by total number of kernels), percentage unpopped, etc.
Now let’s think about what we can measure as a QUANTITATIVE outcome (. it has to result in a number) :
• Total number of kernels popped/un-popped
• Percentage of kernels that popped (or not)
• Volume of popcorn produced
• Weight of popcorn produced
• Maximum size of individual popped corn
• Average size of popped corn

For each bag, count the number of popped and the number of un-popped so that you have a total number of kernels (popped + un-popped). You can then calculate the percentage of popped kernels (number of popped divided by total number of kernels times 655 to get a percentage for example: from Brand X: plain = 78% popped vs. buttered = 55% popped I made those numbers up!). You could then make a bar graph to compare plain vs. buttered for each brand and/or all plain vs. all buttered to show variation between brands. Good Luck once you have the data, if you still have questions just post them here!
When you are driving a car there are two ways to find your destination: drive around randomly until you finally stumble upon what you're looking for OR look at a map before you start. (Which way do your parents drive?)
The control would be room temperature kernels because that is the 8775 regular 8776 or 8775 normal 8776 condition. Your experiment is to change the temperature and see if that change in temperature affects popping compared to room temperature. Good Luck!
First, we'll need to make five different patterns of planes for this paper airplane science fair project. You'll probably want to make three airplanes from each pattern. But don't cheat! You're not allowed to add weight or anything else to it to make it fly better. That will ruin the experiment!
