Approach

Experiential Learning, Project-Based Learning, Collaborative Learning

Materials

Popsicle sticks, Glue, String, Scissors, Measuring tape, Worksheet: Bridge Design Plan, and Discussion: Engineering Principles

Step 1

Introduction

5 mins

Briefly introduce the concept of engineering and its importance in everyday life.
Explain the challenge: to build a bridge that can hold a certain weight using only the provided materials.
Discuss the criteria for success (e.g., strength, stability, creativity).

Step 2

Team Formation and Planning

10 mins

Divide students into small teams.
Distribute the "Bridge Design Plan" worksheet.
Instruct teams to brainstorm and sketch their bridge designs, considering the materials and constraints.

Step 3

Building Phase

20 mins

Allow teams to start building their bridges using the materials provided.
Encourage collaboration and problem-solving as they work.
Circulate the room to provide guidance and support as needed.

Step 4

Testing and Evaluation

5 mins

Once the building phase is complete, test each bridge by gradually adding weight.
Discuss the results with the class, focusing on what worked well and what could be improved.

Step 5

Closure

5 mins

Facilitate a brief discussion on the engineering principles observed during the activity.
Encourage students to reflect on their teamwork and problem-solving experiences.
Collect the "Bridge Design Plan" worksheets for review.

Worksheet

Bridge Design Plan

This worksheet guides students through the planning phase of their bridge-building project. It includes sections for sketching designs and listing materials.

Sketch your bridge design here.

Consider the shape and structure for maximum strength.

List the materials you will use and how you will use them.

Think about how each material contributes to the bridge's stability.

Discussion

Engineering Principles

This discussion will help students reflect on the engineering concepts they applied during the bridge-building activity.

What engineering principles did you use in your bridge design?

Discuss concepts like tension, compression, and balance.

How did teamwork influence your project outcome?

Encourage students to share experiences of collaboration and communication.
