Earth completes one full rotation in about —
What is 24 hours?
These are the living parts of an ecosystem.
What are biotic factors?
Two objects have the same volume, but one sinks in water while the other floats.
Which property explains this difference?
What is relative density?
A toaster changes electrical energy mainly into —
What is thermal energy?

The day-night cycle is caused by —
What is Earth rotating on its axis?
A cactus has thick stems that store water.
How does this help survival?
What is it helps the cactus survive in dry environments?

Wolves hunting in packs is an example of —
What is a learned behavioral trait?
A student must identify a material best suited for electrical wiring.
Which property should the student investigate?
What is electrical conductivity?
A student claims energy disappears after a light bulb is turned on.
Why is this incorrect?
What is energy is transformed, not destroyed?
A student replaces copper wire with rubber tubing in a circuit.
What will MOST LIKELY happen?
What is the circuit will not work because rubber is an insulator?

A student compares four unknown substances.
Which substance is MOST LIKELY a metal?
What is Substance C?
A solar-powered lamp charges during the day and lights at night.
Describe the FULL sequence of energy transformations.
What is light energy → electrical energy → chemical energy → electrical energy → light energy?
A student wants BOTH bulbs in a circuit to stay lit even if one bulb burns out.
Which type of circuit should be used?
What is a parallel circuit?
A flagpole’s shadow points west in the morning and east in the afternoon.
Explain why the shadow changes position.
What is Earth’s rotation changes the Sun’s apparent position in the sky?
Sea turtles hatch and immediately move toward the ocean without being taught.
What type of behavior is this, and how does it increase survival?
What is an instinctual behavior that helps hatchlings reach safety and resources?
