Hi, my name is Amy! I am so happy to be guest-blogging here at Cinnamon’s Classroom!
Are you looking for a fun but educational math activity? Popcorn Volume is a hands-on lesson that compares the volume of different cylinders. My students have really enjoyed doing this activity and are usually very surprised by the results!
Note: This activity is much better if students work in partners.
Step 1: Students cut out the 2-D shapes and tape them securely into cylinders.
Step 2: Students make predictions about the volume of the cylinders.
Step 3: Students fill each cylinder with popcorn kernels, then count the number of kernels that fit in each one. (Note: Some students may need a cup or funnel to help them fill the cylinder.) Students write the results onto the worksheet.
Step 4: Students reflect upon their predictions and compare them to the actual results. Students also measure the cylinders and analyze their volume.
This is a great activity with surprising results. It also takes a bit longer than you might think to complete it, as counting the popcorn kernels takes time. This is a great activity to use on a day before a holiday!
