The Marshmallow Challenge

Introduction

The Marshmallow Challenge is a teamwork activity where participants use spaghetti, tape, and string to build the tallest free-standing structure that can support a marshmallow on top. This unit helps students develop communication, creativity, problem-solving, and English language skills.

Key Vocabulary

  • structure — 結構；建造物
  • measure — 測量；計算
  • stability — 穩定性
  • collaboration — 合作；協作
  • prototype — 原型；初步模型
  • refine — 改良；精進

Grammar Focus

Present Simple

We use Present Simple to describe facts or general actions.
Example: The team works together.

Imperatives

Use imperatives for instructions or commands.
Example: Build the base first.

Comparatives

Use comparatives to compare two things.
Example: This tower is taller than the last one.

Example Sentences

1. Our team measures the height carefully.

2. We work together to keep the structure stable.

3. The marshmallow is heavier than we expected.

  • “Taller is always better.” — Stability matters more than height.
  • “We should plan everything perfectly before starting.” — Rapid prototyping often works better.
  • “The marshmallow is light, so it won’t affect the structure.” — Its weight can easily cause collapse.
