Boat Investigation
11. A group of children want to investigate if the shape of a boat affects how
much weight it can hold. They all make a boat out of tin kitchen foil and
they will float them on a tank of water and fill with weights until the
boat sinks.
What is the one controlled variable they will change?
1 mark
12. Name a variable that must stay the same.

13. What is the variable they will measure and record in their results table?

• Newton
4. What piece of equipment do we use to measure force?
1 mark for either:
• Forcemeter 1
• Newton meter
5. Write TRUE or FALSE next to each of these statements.
a False
b True 1 mark for 2 correct
3 2 marks for 3 correct
c False 3 marks for 4 correct
d True
6. Explain why astronauts move in a bouncy way on the moon.
Answer MUST mention the word gravity.
1 mark for any of:
• There is less gravity 1 No marks for ‘no gravity’
• There is only 1/6 of the gravity of Earth
No marks for ‘they weigh less’
7. Explain why astronauts in space float around.
No marks for ‘no gravity’ as there is always
1 mark for ‘less gravity’. 1
some gravity in space.
8. Label the force that is pushing against this swimmer in the water.
1 mark for water resistance labelled
Water resistance 1
on the diagram.

explain why.
Accept other methods of denoting shape e.g.
a tick.
