Tower Construction and Testing Concepts

The video tutorial guides students through preparing weights for structural tests, building a tower using spaghetti and marshmallows, understanding material properties, and applying building techniques like cross bracing. It concludes with testing the tower's strength by adding weights and evaluating the results.

What is the purpose of using sandwich bags and sand in the lessons?

• To build the tower structure

• To act as a decorative element

• To create uniform weights for testing

• To serve as a base for the tower

What materials are used to build the tower in the design challenge?

• Wood and glue

• Spaghetti and marshmallows

• Plastic straws and tape

• Metal rods and screws

How would you describe the property of spaghetti used in the challenge?

• Heavy and dense

• Brittle and weak

• Soft and malleable

• Flexible and strong

What is the minimum height requirement for the tower in the challenge?

• 20 cm

• 25 cm

• 30 cm

• 35 cm

Why are triangles considered a strong shape in construction?

• They are easy to build

• They are aesthetically pleasing

• They use less material

• They provide stability and strength

What technique is used to strengthen the tower's structure?

• Using glue

• Cross bracing

• Painting the structure

• Adding more marshmallows

How are marshmallows used in the tower construction?

• As a decorative element

• As connectors

• As a base

• As a weight

What is the main focus during the testing process of the towers?

• The color of the tower

• The height of the tower

• The tower's ability to withstand weights

• The speed of construction

How long should the tower withstand the weight during testing?

• 20 seconds

• 10 seconds

• 15 seconds

• 5 seconds

What determines the winning group in the tower challenge?

• The tallest tower

• The fastest construction time

• The most creative design

• The tower that holds the most weights
