What you will need:
- Supply of white and yellow popcorn
- Hot air popper
- Large bowl
- 2 quart measuring cup
- Plastic bag for white and yellow samples
Here’s what you do:
- Draw out a data chart to record final results. Your control variables will be Yellow Kernel Samples 1,2, & 3 and White Kernel Samples 1, 2, & 3. Your results will include Volume, Number of Unpopped Kernels, and Size of Popped Kernels.
- Measure 1 tablespoon of sample #1 kernels.
- Count the kernels and record the number of kernels on the chart.
- Plug in air popper and pop sample #1, using the large bowl to catch the popped kernels.
- Using the measuring cup, measure the sample of popped kernels and record the volume on the chart.
- Count the number of popped kernels and record on the chart.
- Count the number of unpopped kernels and record on the chart.
- Repeat above steps with each sample of popcorn.
Now What Do We Know?
- Which of the samples produced the largest popped pieces?
- Which type of popcorn takes up more room, yellow or white?
- Which sample popped the highest volume?
- How could you use your classmates’ results to find the average volume of popped corn?
