Physics Rocks!


Physics Rocks! is a set of great songs written to teach the basics of physical science. The content is within the grasp of an upper-elementary student, but is still relevant in high school physics and beyond. With these songs, what they learn will always be there when they need it!

Listen to song samples here, and view lyrics below.

Grades 3-6 may be the perfect time for kids to start learning the basics of physical science, but the understanding of scientific principles should endure for a lifetime. Once students have learned these songs, teachers and parents can point to everyday examples of these concepts to reinforce what they have learned in these catchy tunes, and bring science to life.


Matter is anything that takes us space and has weight
And matter can be classified in 1 of 3 states
Matter is measured in terms of weight and mass
The 3 states of matter are solid, liquid, and gas

A solid is a substance that has its own shape
A liquid is a solid melted to a fluid state
A gas occurs when liquid’s heated past its boiling point
The exception, called suspension, happens when
2 states are joined

Simple Machines

Inclined plane, wedge, and screw,
Lever, wheel and axle, and pulley, too
These are the 6 simple machines
That make work easier for human beings

Inclined planes are flat, slanted surfaces
You use less force going longer distances
A wedge is a machine that’s pretty good
For making zippers zip and for splitting wood

A screw is kind of like an inclined plane
wrapped around a bar for mechanical gain
A lever is a bar that helps us get work done
It pivots at a point that we call the fulcrum

The wheel and axle is pretty neat
Like the ones on the cars drivin’ down the street
A pulley helps you change the direction of force
Just a rope around a wheel makes this handy resource



Energy is the ability
To make things move, even things we can’t see
Energy is the ability to do work

The 2 basic forms of energy
are kinetic and potential energy
Kinetic energy is like a running boy
Potential energy is like a wound up toy

The word “kinetic” is an old Greek word
It means “moving” like a flying bird
When energy is stored and ready to use
It’s “potential” like an unlit firecracker fuse


What makes objects fall to the ground?
Why is it when things go up, they always come down?
What keeps the earth in orbit and water in the seas?
It’s an unseen force, it’s gravity
Objects pulling on each other give us gravity

Galileo found that different objects falling down
dropped at the same rate, though he didn’t know how
Isaac Newton found acceleration was the same
for different objects falling – the force of gravity’s to blame

Newton’s Law of Universal Gravitation says
the force of gravity acts between all objects
The pull is greater, the closer things get
And if the mass is greater in one,
it pulls harder on the other object

Earth’s the perfect distance from the sun, we can say
It won’t be pulled in or slowly drift away
This is the same for all the planets and their moons
We couldn’t have a solar system if this wasn’t true

Laws of Motion

In the late 1600s, Sir Isaac Newton
determined that there were 3 laws of motion
He was studying Galileo
and discovered the 3 laws of motion we know
Newton discovered the 3 laws of motion we know

Law 1:  An object in motion will remain in motion
And an object at rest will remain at rest
Objects remain in motion or at rest
Unless acted on by a force, you might have guessed

Law 2:  Force and mass and acceleration
are all related in this law of motion
An object’s mass times acceleration
equals the object’s force, now everyone

Law 3:  This law states that for every action
there is an equal and opposite reaction
If an object puts a force on another object
the second object is sure to push back


Electricity is a form of energy
It can be measured, but it can’t be seen
We use it to make light, motion, and heat
When electrons move or flow along a path
It’s called electricity

When electrons move or flow
through a circuit, we all know
electrical power is either DC or AC
Direct current’s in a battery, now
and alternating current’s in your house
We power our watches and TVs with electricity

Current flows through conductors
but not through insulators
and resistors slow the current’s flow, you see
Current’s measured in amps, I know
and resistance is measured in ohms
And voltage is the push intensity of electricity


A magnet is a piece of metal
that exerts a force on iron or steel
A magnet has a north and south pole
and it’s surrounded by a magnetic field

Magnets can be weak or strong
Magnets can be big or small
And these amazing objects are called magnets

(verse 1)
Particles in metal have a north and south pole
but they’re not lined up in most metal objects
But if those particles do line up
then that piece of metal is a magnet

(verse 2)
The ends of a magnet are called the poles
They’re north and south, “N” and “S”
Two like poles will push away
But unlike poles attract in magnets


Light is a form of energy
Without it, none of us could see
Lightbulbs and the sun up in the sky
radiate this energy we call light

Light always travels in a straight path
unless something makes it reflect or refract
When light bounces off, that’s reflection
but if it bends and passes through, that’s refraction

Objects are called luminous
if they can produce their own light
Everything else is non-luminous
Light reflects off of them into our eyes

Translucent objects let light pass through
but not as easily as transparent objects do
Other objects are opaque, and the light
can’t pass through no matter how hard it tries
