Encourage students to suggest variations of the investigation. For example, they may wish to create a larger air model. To do this, multiply the materials by two or three. Students also may want to remove popcorn from the large bag using the measuring cup to determine how many cups of popcorn must be taken from the large bag before the green popcorn kernel is removed.
