🎯 WALT & Success Criteria

WALT: Investigate water resistance by designing and testing boats to understand buoyancy and material properties.

Success Criteria - Tick when you achieve each one:

I can build a boat that floats on water

I can measure and record how much weight my boat can hold

I can explain why my boat floats or sinks using scientific ideas

🚤 Part 1: Planning & Testing

1. What materials did you choose for your boat?

Aluminium foil

Cardboard

Plastic container

Other: ________________

2. Draw your boat design below:

3. What shape did you make your boat?

Flat and wide

Deep like a bowl

Long and narrow

Other: ________________

4. How much weight could your boat hold before it sank?

My boat held _______ grams before it sank.

5. Did your boat float? Circle your answer and explain why.

YES / NO

🔬 Part 2: Scientific Thinking

6. Why do you think some boats float better than others?

The material is lighter

The shape spreads the weight out

The boat has more air inside

The material doesn't soak up water

7. What is buoyancy? (Sentence starter to help you)

Buoyancy is the force that _________________________________
