Physical Changes
Mass, weight, Density, state,
Mass
Is a measure of matter
Weight is similar
With gravity
Go to the moon
Mass stays as is
But the weight you lose
Will not be missed
There’s a big difference
Between mass and weight
Between mass and weight
Between mass and weight
When it floats,
Or when it sinks
It’s because of density,
Mass over V
Things sink or float
Because of density,
Because of density,
Because of density
Physical change is like
State, or density,
State or density,
State or density
A Solid,
Vibrates in place,
but not a liquid
is slides away
then there’s gas
diffusing free
you can contain it
but up goes T
If T goes up,
so does P
The only way to balance them
Is by changing v
The triple point
Is where all three
States co exist
With pressure and T
Matter has three states,
Based on temperature and pressure
Based on temperature and pressure
A mixture is
Physically combined
It might be all the same
Or look different
A solution is
a liquid mix
Solutes go into
A solvent
Homogeneous,
Means all the same,
Heterogeneous
Differences are plane
Physical changes are like…
State, Mixtures and solubility
State, Mixtures and solubility
State, Mixtures and solubility
Temperature
Measures the average speed
Of a molecule
We cannot see
Kelvin thought
All motion would stop
If it got cold enough,
Like Absolute zero
Thermal energy
Conducts with solids,
But not convection,
Only with fluids
And across space
There is radiation
It moves in waves
Across the spectrum
A wave,
Is pretty clear,
They can reflect
From a mirror
And in a cup,
A pencil bends
It is not a trick,
It is refraction
First radio,
Then infra-red
Roy-g-biv,
UV, X and gamma
Thermal energy,
Conducts, convects and lights
Conducts, convects and lights
Conducts, convects and lights
Nature has,
Four great forces
Electromagnetic,
Strong, weak and gravity
Steven Hawking
Is hoping that
He can find unity
With a single particle
Newton saw,
Matter does not like change,
At rest, it stays at rest
If moving, keep going
And where it goes,
It based on the forces
Vectors show how
They interact
Finally,
There are opposites
A balance for each push
They always react
Mechanical force means,
Opposites, inertia or vectors
Opposites, inertia or vectors
Opposites, inertia or vectors
Mendeleev ordered the elements
Based on periods,
Like atomic number, mass and electronegativity*
This made him guess
There were many more
In order to find them,
We used a particle accelerator!
Madam Curie,
Won two nobel prizes
For discovering,
radiactivity
Bohr noticed that atoms,
Make most sense
With a protons and neutrons,
in the nucleus,
Surrounding those,
Were electrons
Existing in shells
To make chemical bonds
Atomic number
Needs only protons,
But not the mass
It needs also neutrons
A compound
Has different elements
But a molecule
Can be the same
Atoms combine
To make octet
They lower their energy
Or enthalpy
Matter is Made
from atoms, which make molecules
from atoms, which make molecules
from atoms, which make molecules
Electricity,
Is a charge,
Conductors pass it along,
Insulators won’t
Rub a balloon
Or drag your feet
Your can collect charges
Static electricity
Like charges repel
Opposites attracts
Store enough of them
And they’ll react
A battery
Uses metals and acid
The chemistry
Sets electrons free
A series circuit,
Connects end to end,
But parallel,
Means between
Add a load,
The voltage stays
But the current
It drops away
Magnets can be,
Permanent or temporary,
Magnets are made,
Al, Ni, Co, Fe
A field,
Exerts a force,
Like static, magnetic
And Gravity of course
We all live inside a bunch of fields…
Plants make sugar,
From light from the sun,
In the chloroplast
Is where its done
Photosynthesis,
Uses water and carbon dioxide
to make sugar,
which is energy
Everything,
Even you and me,
Has mitochondria
For energy
Respiration,
Takes oxygen and sugar
Breaks sugar down,
Into carbon dioxide and ATP
All things come
From cells with organelles,
From cells with organelles,
From cells with organelles,
Gregor Mendel,
Studied peas,
He selectively bred them,
in a Monastery,
he was the first,
to document
that traits come as genes
with some dominant
heterozygous,
means two different alleles
homozygous means
both are the same
The genetic code,
Genes often have,
Alleles or forms
We get two of them,
Some traits are dominant,
Darwin noticed,
Everything comes from parents,
Almost everything,
Use sex to make variety
But selection,
Produces rarity
And mostly commonly,
Extinction
Our bodies,
Are organized,
Cells, tissues, organs
Systems unify
A disease,
Like a virus or bug
The rock cycle,
Begins below
in the core of the earth
where Igneous flows
But it gets weathered
And dropped to the sea
Where pressure transforms
Into sedimentary
And when faults move,
The rocks get pressed
Without heat
Into metamorphic
Water evaporates
into the atmosphere
It cools as it rises
Condensing onto a chair
The warm equator
Drives air sky high
The freezing poles,
Drives air down low
The air moves around
In predictable ways
Forming circulation cells
That currents obey
Within the sea,
The same is true
Currents result from hot and cold
Like kuroshio
These physical changes,
Produce climate
Like the weather and tides
They never quite
Abiotic forces are like
Rocks, water and wind
Rocks, water and wind
Rocks, water and wind
The earth changed,
From the heavens
The mysterious forces
Keep us even
Oceans rise and fall
Because of the moon,
Pulling water toward it,
As we spin away
Our magnetic field
Pushes solar winds away
Its keeps our atmosphere
Right in bay
And the ozone,
Blocks UV
CFC’s kill it,
Our sweet O3
The axis of the earth,
Produces seasons,
Not our orbit,
It is just perfect
My very excited mother
Just served us Nine pizzas
Which is the order
Of the planets
Beyond our system,
Are other stars,
Connected by gravity
Into galaxies
All of those,
Orbits more
The universe
Is ours to explore
The earth is found inside
Systems, galaxies and the universe
Systems, galaxies and the universe
Systems, galaxies and the universe
