Grade 6 Science practice sheet
Yukon Curriculum · from Gradelings · Name: ______________________
Question 1
Which body system does each part belong to? Tap an item, then tap its basket.
Sort into: ⚡ nervous system · 🚰 excretory system · 🧪 endocrine (hormone) system
- 🎈bladder
- 🔗spinal cord
- 🧠brain
- 🏃adrenal glands
- 💧kidneys
- 🎛️pituitary gland
⚡ nervous system: spinal cord, brain · 🚰 excretory system: bladder, kidneys · 🧪 endocrine (hormone) system: adrenal glands, pituitary gland
Hint: The nervous system carries fast electrical messages. The excretory system removes wastes. Endocrine glands release hormones into the blood.
Question 2
Which tool would quickly separate iron filings from sand?
🧲- a thermometer
- a magnet
- a filter
- a funnel
a magnet
Hint: Iron is magnetic. Sand is not.
Question 3
Which has the most inertia?
- a skateboard
- a loaded truck
- a bicycle
- a tennis ball
a loaded truck
Hint: The more mass something has, the more inertia it has, and the harder it is to start or stop.
Question 4
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 5
Put these in order, starting with the one closest to the Sun.
- Mars
- Uranus
- Neptune
- Venus
- Mercury
Mercury → Venus → Mars → Uranus → Neptune
Hint: Try: My Very Educated Mother Just Served Us Nachos (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The asteroid belt lies between Mars and Jupiter.
Question 6
Put these in order from smallest to largest.
- ✨the universe
- ☀️the Sun
- 🪐our solar system
- 🌌the Milky Way
- 🌍Earth
Earth → the Sun → our solar system → the Milky Way → the universe
Hint: The Moon orbits Earth. Earth orbits the Sun. The Sun and its planets make our solar system, which is one tiny part of the Milky Way. The universe holds billions of galaxies.
Question 7
Which organs filter wastes out of your blood to make urine?
- heart
- bladder
- kidneys
- stomach
kidneys
Hint: You have two bean-shaped kidneys near your lower back. They clean your blood all day long.
Question 8
In a solution, the substance that does the dissolving is the…
- solvent
- suspension
- filter
- solute
solvent
Hint: In salt water, water is the solvent and salt is the solute.
Question 9
What is inertia?
- an object's resistance to a change in its motion
- how bright an object is
- the force that pulls objects toward Earth
- the rubbing of two surfaces
an object's resistance to a change in its motion
Hint: A still object stays still and a moving object keeps moving, unless a force changes it.
Question 10
What happens to the pull of gravity between two objects as they move farther apart?
- It disappears instantly
- It stays exactly the same
- It gets weaker
- It gets stronger
It gets weaker
Hint: Gravity depends on mass and distance. The farther apart, the weaker the pull.
