Year 6 Science Exploration

You are part of a science team exploring how Earth and physical systems work. Read each question carefully. Use evidence and science words in your explanations. Word bank: reproduce, water, sunlight, energy.

Earth in space

Explore sunlight, seasons and the Moon.

1.What causes Australia to have warmer and cooler seasons during the year? Choose the best explanation.

Earth moves much closer to and farther from the Sun.
Earth’s tilted axis changes the angle and length of sunlight during the year.
The Sun switches between hot and cool settings.
The Moon blocks sunlight for part of each year.

2.During a full Moon, the Moon looks bright from Earth. Is the Moon making its own light, or reflecting sunlight? Explain what the Moon’s phases show us about its position.

Forces at work

Investigate what changes the motion of objects.

3.A scooter slows down when its rider squeezes the brakes. Which force mainly helps the brake pads slow the wheel?

Gravity
Friction
Magnetism
Buoyancy

4.A student pushes the same toy cart with a gentle push and then a stronger push. If the cart is free to move, what is likely to happen with the stronger push?

5.A ball rolls across smooth tiles and then across thick grass. On which surface will it usually stop sooner? Explain the role of friction.

6.Match each situation to the force that best explains it.

A dropped gum leaf falls towards the ground.
A bicycle tyre grips the road as it turns.
A compass needle turns towards north.

Friction
Gravity
Magnetism

Living things and environments

Look for the ways organisms survive and depend on one another.

7.In this food chain, grass is eaten by a grasshopper, and the grasshopper is eaten by a lizard. Identify the producer, the primary consumer and the secondary consumer.

8.Complete the statement using the word bank in the instructions: Living things can grow, respond to their surroundings and .

9.Complete the statement using the word bank in the instructions: A cactus has spines rather than broad leaves, which helps it reduce loss.

10.A lizard living in a hot, dry place is active in the cooler morning and hides during the hottest part of the day. Explain how this behaviour may help it survive.

Plan a fair test

Use careful observations to compare friction on different surfaces.

11.Your team wants to find out which surface makes a wooden block hardest to slide. Name one thing to change, one thing to measure and two things to keep the same. Describe how you would make the test fair.
