## Marble Mazes

Objective: Children will tinker with marbles and tubing to discover how the shape and steepness of the tube affects movement.

## What You Will Need

• Pegboard – 3' × 4' pieces (available inexpensively at hardware or home improvement stores)
• Foam pipe insulation tubes – 1" diameter (available inexpensively at hardware and home improvement stores)
• Masking tape – 1 roll
• Plastic tie wraps - 8" length
• Large (5/8") marbles

## What To Do

Note: Divide the children into groups of 4.

1. Cut pieces of the tubing into different lengths.
2. Give each group a few lengths of tubing and some marbles.
3. Tell the children to tinker with these materials.
4. Challenge them to try figure out how they can put the marble in one end of the tubing and have it roll out of the opposite end.
5. Ask the children what they can do with the tubing to make the marble roll differently (see Guiding Student Inquiry).
6. Demonstrate connecting different lengths of tubing using masking tape. Show children how to make loops, curves, spirals, and ramps.
7. Assist the children with connecting their tube mazes to the pegboard with the tie wraps.
8. Encourage children to try out the mazes created by other groups.

## Guiding Student Inquiry

• Describe what we can do with these materials.
• Explain how you can make the marble roll faster.
• Tell me what you think will happen if we add another piece of tubing.
• Describe what you can do to the tubing to change the path of the marble.

## Explore, Extend & Integrate

• Have races to see which maze the marbles pass through the fastest.
• Encourage children to create marble mazes with other materials such as blocks, Legos, craft sticks, and discarded cardboard tubes and boxes.
• Make marble paint mazes by rolling a marble in paint. Place it on a sheet of white construction paper placed in the bottom of a shirt box. Tip the box different ways to create a marble maze on the paper. Add marbles covered in different colors for variety.

## Check for Children’s Understanding

• Could children explain that raising one end of the tubing would make the marble roll faster?
• Could children explain that the marble would have a longer path if additional tubing were added?
• Could children describe that the path of the marble would change by adding curves, loops, and spirals?

#### Did You Know?

Motion is defined as a change in position. The marble rolling through the tube is an example of a simple motion. The motion becomes more complex when the tube is twisted. Another example of complex motion is when the tube is tilted, creating a ramp. The tilting of the tube is a force, which causes the marble to increase speed. A marble moving through a maze is another complex motion.

Mazes can be made of hedges, mirrors, wood, or other things. Corn mazes are the most common type of maze in the United States. Mazes have been part of history for thousands of years. The winding path of a maze was thought to be for spiritual journeys.

#### Lesson Tips

• Instead of plastic tie wraps, bendable wire can be used (by teachers only) to secure the foam to the pegboard. After twisting the wire to hold the foam in place, be sure to cover sharp wire edges with tape.
• Cardboard paper towel tubes and gift-wrap tubes can be used in place of foam insulation tubing.
• Place additional foam insulation tubing and marbles in the discovery area for further investigation. Adult supervision is recommended.
