Designing with Components

Designing with components thrives with active learning because students learn best by doing. Hands-on building challenges allow students to directly experience how material properties affect structural integrity, moving beyond abstract concepts to concrete understanding.

Activity 01

• 60 min · Small Groups

Bridge Builders Challenge

Provide students with craft sticks, tape, and glue. Challenge them to design and build a bridge that can span a set distance and support a small weight, like a toy car. They must explain why they chose specific materials for different parts of the bridge.

Construct a stable structure using a limited number of pieces.

Facilitation Tip

For the Bridge Builders Challenge, guide students during the Project-Based Learning planning phase to define clear success criteria for their bridge, such as weight-bearing capacity or span length.

Shelter Design Studio

Students are given a small toy figure and a collection of materials like cardboard, fabric scraps, and pipe cleaners. Their task is to design and build a shelter that can protect the figure from a simulated 'rain' (a gentle spray from a water bottle).

Justify the selection of specific components for different parts of a design.

Facilitation Tip

During the Shelter Design Studio, encourage students to use Peer Teaching to explain to each other how the choice of fabric or cardboard impacts the shelter's ability to protect the toy figure from simulated 'weather'.

Component Sorting and Justification

Present students with a variety of building components (e.g., blocks of different shapes, sizes, and materials). Have them sort these components based on their properties (e.g., strong, flexible, heavy) and then explain which component would be best for a specific structural element, like a strong base.

Critique a peer's design, suggesting improvements for stability or function.

Facilitation Tip

In Component Sorting and Justification, facilitate student discussions where they explain their reasoning for grouping components, referencing the properties they observed during the activity.

A few notes on teaching this unit

This topic benefits from a Project-Based Learning approach where students tackle authentic design challenges. Avoid simply presenting component types; instead, provide opportunities for students to discover material properties through experimentation and iterative testing. Encourage students to document their design process, including failures, as these are crucial learning opportunities.

Successful learning looks like students confidently selecting and combining components, justifying their choices based on material properties and intended function. Students will demonstrate iterative design thinking by testing their creations, identifying areas for improvement, and revising their structures to meet specific criteria.

Watch Out for These Misconceptions

• During the Component Sorting and Justification activity, students may initially think all components are interchangeable.

  Redirect students by asking them to test how different components perform when subjected to similar forces, like bending or compression, and to justify why certain materials are better suited for specific structural roles based on these observations.

• In the Bridge Builders Challenge, students might believe a structure is stable if it just stands up.

  Prompt students to test their bridges by gently shaking them or placing small weights on them. Encourage peer feedback on how the structure reacts to these forces, helping them understand that true stability involves resisting movement and potential collapse.
