First Investigation

Try to move the water from one bucket to the other bucket
through the tube. How can you do it?

Classroom Materials

Each pair of students should have:

two containers that can hold at least a quart of water

one length of tubing (about 4 feet long) per student

water (with one drop of bleach per gallon of water)

For hygenic reasons, it's important that each student
have their own tubing and they do not share with other students.
Be careful not to provide any visual clues to the students
by placing the buckets in any particular relationship.
