Key Vocabulary

Standard: Fill in the definition. | Support: Definitions shown in grey — read and copy into your folio. | Extension: Use each term in a sentence.

Term	Definition	Use in a sentence (Extension)
Buoyancy	The ability of an object to float in water
Waterproof	Able to keep water out; not damaged by water
Structure	The way parts are arranged to support weight or hold shape
Prototype	A first version or model of a design, used for testing
Constraint	A rule or limitation you must follow when designing
Iterate	To repeat a process, making improvements each time

⚪

Design Challenge: Circle Challenge (Folio p. 13)

Turn as many circles as you can into recognisable objects or pictures. Be creative!

How many circles did you complete?

What was your most creative circle design?

✏

Design Challenge: Texture Copying (Folio p. 14)

Copy the texture patterns as carefully as you can in your folio. Rate your accuracy below.

Which texture was hardest to copy? Why?

🚢

Design Challenge: Paper Boat (Folio p. 15)

Brief: Design and build a paper boat that holds as many marbles as possible without sinking.

Constraints: 1 sheet of A4 paper • No tape or glue • Must float for 10 seconds

Planning	Results
	Marbles held: Float time: seconds

Reflection: What worked well? What would you change?

🔵 Support — Paper Boat Tips

Fold your paper in half lengthways first
Turn up the edges to make walls (at least 2 cm high)
Pinch the corners tightly to stop water getting in
A wider base = more stable = holds more marbles

🟠 Extension — Buoyancy Investigation

Can you design a boat that holds 10 or more marbles? Explain why your design works using the word buoyancy.

Improved design description:

Research: Who was Archimedes and what did he discover about floating objects?

Exit Ticket — Reflection

1. What does the word “iterate” mean? Give an example from today.

2. What worked best in your paper boat design? Why?

3. If you could redesign your boat, what ONE change would you make?
