Engineering design in Grade 5 Science comes to life when students compare possible solutions, test prototypes, and use evidence to decide which design works best. Solution Development: Test, Compare, Improve is a hands-on learning stations activity focused on evaluating engineering solutions to real-world problems using defined criteria and constraints.

Rather than choosing a design based on preference alone, students consider how well different solutions perform. They explore evidence about strength, water retention, durability, and safety to justify a preferred option. This gives students a concrete way to connect engineering design decisions with testing, comparison, and evidence-based reasoning.

What students investigate

The activity focuses on the decision-making that happens as engineers develop and evaluate solutions. Students work with key ideas such as:

• Criteria and constraints: Use defined measures and limitations to evaluate possible solutions to a problem.
• Prototypes and models: Explain how models and prototypes help test how well a design may perform.
• Performance evidence: Compare solutions using information about strength, water retention, durability, and safety.
• Evidence-based decisions: Justify why one solution is preferable by referring to its performance against the stated criteria.

These concepts give students practice with engineering design reasoning instead of relying on unsupported opinions about which solution is best.

Inside the resource

• Station cards: Present the case-study material students visit and examine as they work through the activity.
• Station recording sheet: Gives students a place to record information and their thinking while visiting stations.
• Station wrap-up: Provides a concluding activity for bringing together observations and comparisons.
• Answer Key PDF with Teacher Guide: Includes learning objectives, teaching tips, discussion questions, and common mistakes to support instruction and review.

How to use it in class

Place the station cards around the classroom and organise students into small groups. Groups begin at different stations, read the relevant case-study card, and record their findings on their own recording sheets rather than writing on the cards. After the allotted time, students rotate to the next station until they have visited every station. Bring the class together afterward to compare the cases and discuss how the available evidence supports different engineering decisions.

This structure works for a guided science lesson, a collaborative classroom activity, or a review of engineering design concepts. The recording sheet keeps student thinking organised, while the wrap-up creates an opportunity to connect individual station observations to broader decisions about solution performance.

Why this activity is useful

Choosing between engineering solutions involves more than identifying a possible answer. Students need to consider what makes a solution successful, recognise limitations, examine test results, and explain their choices. This Grade 5 engineering design activity gives them a structured opportunity to practise those connected skills while comparing real-world solution possibilities. The included Teacher Guide also provides practical support for preparing the activity, facilitating discussion, and addressing common mistakes.
