What is a solution?
Evenly mixed mixture
What happens when forces are balanced?
No change in motion
What is the formula for speed?
Distance ÷ time
What causes earthquakes?
Plate movement
What is natural selection?
Survival of best traits
Why does a metal spoon feel colder than a wooden spoon at the same temperature?
Metal conducts heat better
What are the parts of a solution?
Solute and solvent
What happens when forces are unbalanced?
Motion changes
A car travels 60 m in 6 s. Speed?
10 m/s
What boundary forms mountains?
Convergent
What is an adaptation?
Trait that helps survival
A car suddenly stops and passengers move forward.
Which law explains this AND why?
Newton’s 1st Law (inertia)
Salt dissolves in water. Identify solute and solvent.
Salt = solute,
water = solvent
A soccer ball is kicked. What caused the motion change?
Unbalanced force
Two runners finish same race, one takes less time. Who is faster and why?
One with less time (higher speed)
Two plates move apart. What boundary?
Divergent
Dark moths survive better in polluted area. Why?
Camouflage advantage
Boiling water shows bubbles rising and heat spreading.
What TWO types of heat transfer are happening?
Convection and conduction
Why is air considered a mixture?
Made of multiple gases
What happens?
No movement
Which is faster?

Steeper line

What boundary?
Transform

What drives natural selection?
Environment
Explain what TWO factors keep the planet in orbit.
Gravity pulling inward + forward motion
How can mixtures be separated?
Physical methods (filtration, evaporation)
Explain inertia.
Objects resist changes in motion
What does a flat line on a distance-time graph mean?
No movement
Why do volcanoes form at plate boundaries?
Magma rises through cracks
Explain how traits are passed on.
Surviving organisms reproduce and pass traits
Two plants of the same species produce offspring with different traits.
Explain how this increases survival using BOTH heredity and environment.
Variation allows some traits to survive better in changing environments
