Find out how much space an apple takes up.
Fill a container partway with water. Use tape to mark the water level. Place an apple under the water so that (as much as possible) your fingers are not underwater. Use tape to mark this new water level, then remove the apple. The space between the two marks is equal to the volume
of the apple. Use a measuring cup to fill the container to the upper mark. How many ounces of space does the apple take up? (Hint: One cup equals eight ounces.)
