Creative Explorations: Discovering the Visual World · 2nd Year

Active learning ideas

Building Up: Skyscrapers

Active exploration helps students grasp abstract concepts like structural stability, because they see cause and effect firsthand. When students manipulate cardboard and test shapes, the physics of compression and tension become visible and memorable, not just theoretical. This hands-on work builds spatial reasoning skills that are essential for future engineering tasks.

Activity 01

• Inquiry Circle
• 40 min · Small Groups

Inquiry Circle: The Strongest Shape

Groups are given paper and tape. They must create three 'columns' (a cylinder, a triangle prism, and a square prism) and test how many books each can hold before collapsing, recording their data.

Analyze the structural principles that enable a very tall building to remain upright.

Facilitation Tip

During The Strongest Shape, rotate the room to listen for groups describing how folds or tubes distribute weight differently from flat sheets.

What to look for

Present students with three pre-made cardboard shapes (e.g., a flat sheet, a rolled tube, a triangular prism). Ask: 'Which shape do you predict will be strongest for building a tall tower? Why?' Observe student responses to gauge understanding of shape strength.

Activity 02

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: The Foundation Fix

Students sketch a plan for a 'wide base' for their skyscraper. They swap with a partner who must 'critique' the design by pointing out where it might tip over, suggesting a fix using tabs or weights.

Explain how a flat piece of cardboard can be transformed into a strong three-dimensional shape.

Facilitation Tip

During The Foundation Fix, pause pairs after their discussion to ask one student to physically demonstrate the change they suggested.

What to look for

After students build their initial skyscraper models, have them pair up. Each student points out one feature of their partner's tower that they think makes it strong, and one feature that could be improved for stability. Prompt: 'What specific change would you suggest to make your partner's tower taller or stronger?'

Activity 03

• Simulation Game
• 30 min · Whole Class

Simulation Game: The Earthquake Test

Once structures are built, students place them on a 'shaky table' (a piece of cardboard on top of tennis balls). They observe which buildings stay standing and discuss which construction techniques (like cross-bracing) helped.

Differentiate between strong and weak shapes for constructing building foundations.

Facilitation Tip

During The Earthquake Test, ask students to predict which tower will survive before the shake, then have them revise their reasoning afterward.

What to look for

Students draw a simple diagram of their skyscraper model. They label the base and one example of reinforcement. Then, they write one sentence explaining why their base is important for keeping the tower upright.

A few notes on teaching this unit

Teachers should emphasize process over product, encouraging students to test and iterate rather than aim for a perfect initial build. Avoid rushing to the 'right' answer, as students learn more from failed tests and redesigns. Research shows that guided inquiry, where teachers ask probing questions but let students explore solutions, leads to deeper understanding of structural principles.

By the end of these activities, successful students will confidently explain why certain shapes and reinforcements create stronger structures. They will apply this knowledge to build taller, stable towers and justify their design choices using terms like 'base,' 'reinforcement,' and 'center of gravity.' Their models and discussions should reflect thoughtful problem-solving, not just trial and error.

Watch Out for These Misconceptions

• During Collaborative Investigation: The Strongest Shape, watch for students who believe adding more tape will make their cardboard tower stronger.

  Redirect them to test three shapes: a flat sheet, a rolled tube, and a folded triangular prism. Have them compare stability and explain why the tube or prism holds more weight with less tape.

• During Simulation: The Earthquake Test, watch for students who build towers with uniform width from base to top.

  Provide pyramid-shaped examples and have them rebuild with a wider base and narrower top. Ask them to explain how this design distributes force during a shake.
