The newspaper tower challenge is a hands-on STEM project where students build the tallest tower they can using rolled newspaper and tape. It matters because it turns simple classroom materials into a real engineering problem about height, strength, and balance. Students quickly see that a tower must do more than stand tall, it must stay stable when gravity pulls it downward.
The challenge rewards careful planning, testing, and improving a design after each trial.
Key Facts
- A wide base helps a tower resist tipping because it increases the support area.
- Triangles are strong shapes because they do not change shape easily when pushed or pulled.
- Center of mass should stay above the base for the tower to remain stable.
- Compression is a squeezing force that acts on vertical tower supports.
- Tension is a pulling force that can act in braces or taped connections.
- Strength-to-weight ratio = maximum load held / tower weight.
Vocabulary
- Structure
- A structure is an object built from parts that support loads and keep a shape.
- Base
- The base is the bottom part of a tower that touches the table and supports the rest of the structure.
- Center of mass
- The center of mass is the average position of an object's weight.
- Brace
- A brace is a support piece added at an angle to help a structure stay stiff and stable.
- Prototype
- A prototype is an early model used to test and improve a design.
Common Mistakes to Avoid
- Making the base too narrow, which is wrong because a tall tower with a small support area tips over easily.
- Using only vertical newspaper tubes, which is wrong because the tower may bend or twist without diagonal braces.
- Adding too much tape at the top, which is wrong because extra weight high above the table raises the center of mass and makes tipping more likely.
- Skipping tests during building, which is wrong because small bends, loose joints, and weak spots are easier to fix before the tower is finished.
Practice Questions
- 1 A tower is 120 cm tall and its base is 30 cm wide. What is the height-to-base ratio, written as height / base?
- 2 A student has 12 newspaper tubes. They use 4 tubes for the square base and 4 tubes for vertical supports. How many tubes are left for diagonal braces?
- 3 Two towers are the same height. Tower A has a wide triangular base and diagonal braces. Tower B has a narrow square base and no braces. Explain which tower is more likely to stay standing and why.
