How many steps are in the scientific method?
Five steps.
100
What is an observation?
Information from your senses.
100
What is weight?
The gravitational pull on an object.
100
What is gravity?
It is the force that pulls things towards the center of the Earth.
100
What is mass?
The amount of matter in an object.
200
What is a hypothesis?
A statement of what you think will happen and why.
200
What is an inference?
An untested conclusion based on your observations.
200
Is your weight the same on all of the planets?
No
200
What is a force?
A push or pull of any kind.
200
What as less mass? The Earth or the Moon.
The Moon.
300
What is a procedure?
A series of steps in an experiment.
300
Observation or inference? The plant needs more sunlight.
Inference

Earth's gravitational pull just got five times stronger! What happens to your weight?
My weight increases. I will weight five times heavier.
300
On Earth, in what direction does gravity pull objects?
Gravity pulls objects towards the center of the Earth.
300
What has more mass: a textbook or a piece of folder paper?
A textbook

Give me an example of a hypothesis. (Use the right format).
"If....then..."
400
Observation or inference? The rock is shaped like a rectangle.
Observation
400
How are weight and mass different?
Weight changes as the gravitational pull changes; mass stays the same.
400
The moon is moving closer to Earth. What will happen to the gravitational force between Earth and the moon?
The gravitational force will become stronger.
400
How does mass affect gravity?
The larger and closer two masses are, the more gravitation affects them.
500
What needs to be included in a procedure?
A list of materials and steps of conducting an experiment. Steps must be in order.
500
Observation or inference? The grass is green.
Observation

Why is your weight different on different planets?
Every planet has a different gravitational pull because of its mass.
500
The Earth shrank. What will happen to the gravitational force between the Earth and the sun?
The gravitational force will become weaker.
500
How do you know that the moon has less mass than the Earth? (Hint: Think of orbits).
The moon orbits around the Earth because the Earth has more mass which means it has a greater gravitational pull.
