Question 1
Why should a data table be neat and labelled with units?
- To make it longer
- To hide mistakes
- So others can read and check the data
So others can read and check the data
Hint: Clear communication helps.
Question 2
A scientific theory or model is the one that…
- is the most popular
- is the oldest
- best fits the evidence at the time
best fits the evidence at the time
Hint: Models can change as new evidence appears.
Question 3
In a tug-of-war, the Blue team pulls left with 250 N and the Gold team pulls right with 230 N. What is the net force on the rope?
Pulling force (N) - 480 N to the left
- 0 N (balanced)
- 20 N to the left
- 20 N to the right
20 N to the left
Hint: When forces point in opposite directions, subtract the smaller from the larger. The net force points the way of the bigger force. Equal forces are balanced: the net force is 0 N.
Question 4
What does density tell you?
- How much mass is in a given space
- How hot an object is
- How fast it moves
How much mass is in a given space
Hint: Dense objects pack a lot of mass into a small volume.
Question 5
Which adaptation helps a bird fly?
- Hollow bones and feathers
- Gills
- Thick scales
Hollow bones and feathers
Hint: Light bodies and wing feathers help lift.
Question 6
A hockey stick hits a puck. Energy transfers from the stick to the…
- ice only
- puck
- the arena roof
puck
Hint: Motion energy passes to the puck.
Question 7
What is the function of the battery in a circuit?
- To provide the energy that pushes current through the circuit
- To make light only
- To control which wire is used
To provide the energy that pushes current through the circuit
Hint: It's the energy source.
Question 8
Why should you never use a hair dryer near a filled bathtub or sink?
- The dryer might get too cold
- Water can carry electricity and cause a shock
- It will make the water boil
Water can carry electricity and cause a shock
Hint: Water and electricity are a dangerous mix.
Question 9
Why do we always see the same side of the Moon?
- Earth hides the other side
- The Moon rotates once in the time it orbits Earth once
- The Moon does not rotate at all
The Moon rotates once in the time it orbits Earth once
Hint: Its rotation and orbit match.
Question 10
Which is a learned behaviour?
- a puppy having brown fur
- a bird having wings
- a dog learning to sit on command
a dog learning to sit on command
Hint: You learn behaviours through experience.
