When a roller coaster goes down a hill, its energy changes from:
Slow to fast
High to low
Stored to moving
Quiet to loud
Heat is a type of:
Light
Sound
Energy
Color
When a car moves, it uses:
Sleeping energy
Moving energy
Colorful energy
Quiet energy
A ball rolling down a hill shows:
Energy staying still
Energy changing
Energy disappearing
Energy getting smaller
Which keeps things moving?
Pushing
Thinking
Singing
Sleeping
Renewable energy means:
Energy that runs out quickly
Energy we can make again and again
Energy that is expensive
Energy that is heavy
When you climb stairs, you use:
Sleeping energy
Thinking energy
Moving energy
Singing energy
A wind turbine turns:
Water into electricity
Wind into electricity
Rocks into electricity
Trees into electricity
Solar panels change:
Moonlight into electricity
Sunlight into electricity
Starlight into electricity
Candlelight into electricity
When a spring is squeezed, it has:
Moving energy
Stored energy
Sleeping energy
Singing energy
A moving bicycle has:
Stored energy
Quiet energy
Moving energy
Colorful energy
Energy can:
Only be created
Only be destroyed
Change from one type to another
Stay exactly the same always
The difference between mass and weight is:
Mass changes with gravity, weight stays the same
Mass stays the same, weight changes with gravity
Both mass and weight are always the same
Mass and weight are completely different things
Newton's First Law of Motion says that an object will:
Always move when pushed
Stay still or keep moving unless a force acts on it
Stop moving immediately when touched
Change color when moving
When you push a shopping cart, Newton's Second Law shows that:
Heavier carts are easier to move
Lighter carts require more force to move
Force depends on the cart's mass
Carts always move the same way
Newton's Third Law means that:
For every action, there is an equal and opposite reaction
Bigger things always move faster
Things only move when pushed hard
Forces always make things stop
The formula for Weight is:
Mass × Gravity
Mass + Gravity
Mass ÷ Gravity
Mass - Gravity
Convert 3 km to millimeters:
3,000 mm
300,000 mm
30,000 mm
3,000,000 mm
Convert 5 kg to milligrams:
5,000 mg
50,000 mg
5,000,000 mg
500,000 mg
Potential energy depends on:
Height and mass
Color and shape
Sound and smell
Temperature only
Kinetic energy depends on:
An object's position
An object's mass and speed
An object's color
An object's smell
The Law of Conservation of Energy means:
Energy can be created or destroyed
Energy can change but total amount stays the same
Energy disappears sometimes
Energy is always the same type
In the kaleidoscope experiment, the independent variable would be:
The color of glass used
How the kaleidoscope works
The design of the kaleidoscope
The person making the kaleidoscope
In a parachute experiment with 3 trials, the controlled variable is:
The length of the parachute
The height of the drop
The weight of the object
The person dropping the parachute
In the egg drop experiment, the dependent variable is:
The height of the drop
The type of padding used
Whether the egg breaks
The size of the egg
An independent variable is:
Something you cannot change
Something you deliberately change
Something that stays the same
Something that happens by accident
A dependent variable:
Is something you control
Depends on the independent variable
Never changes
Is always the same
Gravity always:
Pushes objects up
Pulls objects down
Makes objects move sideways
Changes object's color
An egg is more likely to break when dropped from a higher place because:
Gravity becomes stronger
The impact force increases
The egg gets heavier
The egg changes shape
In a parachute experiment, a larger parachute will:
Fall faster
Fall slower
Stay in the air forever
Disappear
To protect an egg from breaking when dropped, you should:
Make the egg heavier
Add padding to reduce impact force
Drop it on soft ground only
Use a smaller egg
The speed of a falling object depends on:
Its color
Gravity and air resistance
The person dropping it
The time of day
Energy transformation in a kaleidoscope involves:
Light changing shapes
Light reflecting and changing direction
Light disappearing
Light changing color
In the egg drop experiment, the main scientific principle is:
Color change
Impact force and energy absorption
Gravity making things float
Objects becoming lighter
A parachute works by:
Creating more air resistance
Reducing gravity
Making objects lighter
Changing object's color
When an object falls, its potential energy:
Stays the same
Converts to kinetic energy
Disappears
Changes color
Impact force depends on:
Drop height
Object's color
Time of day
Air temperature
In a scientific experiment, you should:
Change many things at once
Keep most things the same
Guess the results first
Use the first result
When doing multiple trials, you:
Do the experiment once
Repeat the experiment several times
Never repeat the experiment
Change the experiment each time
Scientific observations should be:
Based on feelings
Exact and measurable
Random and unclear
Always the same
A good scientific conclusion:
Is based on one try
Explains what happened and why
Ignores the results
Changes the experiment
Measuring in science is important because:
It makes experiments look good
It helps get accurate, repeatable results
It is not necessary
It makes experiments complicated
