What you will need:

  • Supply of white and yellow popcorn

  • Hot air popper

  • Large bowl

  • Tablespoon

  • 2 quart measuring cup

  • Plastic bag for white and yellow samples

Here's what you do:

  1. 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.


  2. Measure 1 tablespoon of sample #1 kernels.


  3. Count the kernels and record the number of kernels on the chart.


  4. Plug in air popper and pop sample #1, using the large bowl to catch the popped kernels.


  5. Using the measuring cup, measure the sample of popped kernels and record the volume on the chart.


  6. Count the number of popped kernels and record on the chart.


  7. Count the number of unpopped kernels and record on the chart.


  8. 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?
