What is a shadow?
A dark shape made when something blocks light.
Can you name two things that a force can do to an object? (mention one)
It can make it move and change its shape.
What is the unit we use to measure force?
Newtons
Can you name one object that is translucent?
Wax paper or frosted glass.
What do you need to make a shadow?
A light source and an object.
What is gravity?
Gravity is the force that pulls things down to the ground.
What is friction?
Friction is a force that slows down objects when they rub against each other.
What does an opaque object do to light?
It blocks the light completely.
Why do shadows change size?
Because the object or the light source moves.
What happens when you jump? Why do you come back down?
Gravity pulls you back to the ground.
Does friction make things go faster or slower?
Slower
Is a window transparent or opaque?
Transparent
Can a transparent object make a shadow?
No
Is gravity a push or a pull force?
A pull force
Name one surface with a lot of friction and one with little friction.
Carpet (a lot), ice (a little).
What type of object lets some light pass through but not all?
Translucent
What kind of object makes a dark and clear shadow?
An opaque object.
