Fixed shape & volume. Cant be compressed
Particles vibrate about a fixed position
Heat gives particles more energy to vibrate vigorously. Enough heat allows them to move far enough apart to go onto the next phase.
Not a lot of energy but strong bonds

Liquids:

Variable shape and fixed volume. Can't be compressed, can bepoured
Particles move further apart & are able to move around and slide over each other
Bonds that hold particles together are weaker than those in a solid. Particles have more energy than those in a solid.
Weaker bonds than a solid, more energy than a solid

Gases:

Variable shape & volume
Gases diffuse/spread out to fill available space
Particles move very fast and very far apart.
Have lots of energy but weak bonds.

Filter water & toxins
Urine productions
Urine storage
Excrete urine

Filtration is when blood is filtered by kidneys and contains toxins.

Urine production is when the clean blood returns to the circulatory system and the toxins are remove from blood and exit kidneys through ureters.

Urine storage is when urine arrives at the bladder and is stored there until it should be removed.

Urination is when the bottom of the bladder opens which makes the urine exit via the urethra to outside world and removes all excess water & toxins

Many substances expand when heated
When heated, the particles (atoms or molecules) in a substance vibrate more
This means they need more space
So the substance expands

Contraction:

The opposite happens when most substances are cooled
The particles vibrate less
They need less room
The substance contracts

*The particles do not expand themselves!

the atomic number of an atom is the amount of protons in the nucleus.
the amount of protons in the nucleus will be the same as the amount of electrons in the atom.
The atomic number is smaller than the mass number/ atomic mass

Atomic Mass

Atomic Structure:

Electrons are arranged in Energy levels or Shells around the nucleus of an atom
First Shell -- max of 2 electrons

Can be chemical or physical
chemical - organisms secrete acids that disintegrate some rocks
physical - when plant roots grow into or inside of rocks causing the rocks to crack

Chemical Weathering

Processes which change the chemical composition of rocks and minerals

- Factors

Climate - warm maximises chemical reations
Plants and Animals - seretion
Time - longer contact, greater change
Mineral Composition - Some minerals are more susceptible to change

- Processes

Dissolving
Oxidation
Hydrolisis

- Dissolving

Water often containing dissolved acids, will dissolve minerals in a rock leaving cavities in the rock
Carbonation
Precipitation - sulfur and nitrogen
Acid rain - when water reacts with gases in the atmosphere forming acid rain

- Oxidation

Minerals may combine with oxygen which forms new minerals which are not as hard

- Hydrolisis

Minerals may combine with water which forms ew minerals that are not as hard

Physical Weathering
Weathering that breaks a rock into smaller pieces without altering its chemical composition.

- Processes

Frost wedging
Frost heave
Thermal expansion and contraction
Mechanical Exfoliation
Abrasion

- Frost Wedging

When water settles between rock crevices, it may freeze causing it to expand. This causes masses of rocks to break or crack.

- Frost heave

Repeated freezing and thawing of ground water. This means the land is continuously rising and falling.

- Thermal Expansion and Contraction

when a material is repeatedly heated and cooled it causes the material to crack

- Exfoliation

Top layer of rock is weathered away leaving the next layer oxposed.

- Abrasion

Small sediment can be carried through the air by wind, through moving streams or rivers or carried down hill by gravity.
When these sediments hit larger rock clasts, it can break off pieces of rock from the surface.

The moving of sediments from one location to another

Agents of Erosion

water (glaciers, water)
wind
gravity

Water

Moves material (both small and large) down streams, rivers, ect.

Glacial

Glaciers carry and move rock clasts that are in them

Wind

Picks up small pieces of rock and carries them through the air.

Formed from sediments of dead living organisms
Are organic
Eg - Coal and chalk

light is emitted
gas is produced
colour change
temperature increase
precipitate it formed

Elements are arranged left to right and top to bottom in order of increasing atomic number
Elements have different atomic numbers and these increase up the table

Periods:

The different rows of elements are called periods.
Atomic numbers and atomic masses increase as you move from the left to the right in a period
All atoms of the elements in the same period have the same number of orbitals/levels

Columns:

The different columns of elements are called groups
Elements in the same family have similar properties
Atoms of elements in the same group have the same number of electrons in the outer orbitals of their atoms

A table consists of vertical columns and horizontal rows in which information is recorded
Each column should have a heading
If a column contains measurements, the units should be written with the heading
Results should be written in order
Must use a ruler

When a chemical change occurs it is called a chemical reaction
Chemical reactions can be shown by using a chemical equation

Reactant + Reactant  Product + Product.

Graphs are diagrams that present information in a visual way
It makes the information easier to understand
Trends and relationships are easier to see.

Data is the information scientists collect by observation and measurement
Interpreting data means finding some pattern in the data that gives an answer to the problem
Graphs makes interpreting data easier because they provide a clearer picture of the data that has been collected

The shape of the graph can be used to get data that was not collected in the investigation
This is called interpolation.

Graphs can be used to predict what will happen outside the range of data displayed on the graphs
This is called extrapolation
It is the extension of the graph beyond the data that has been collected.

The variable you change on purpose

Dependant Variable (DP):

The variable you measure to see the effect of changing the independant variable has made

Hypothesis:

Prediction of the effect you expect from the independant and dependant variable

Aim:

Statement of purpose of the experiment. What your trying to find out

Controlled Variable:

List of all things (except IV & DP) that could affect the experiment if they are not kept the same
Keeping controlled variables the same and only changing the idependant and dependant variables make it a 'fair test'

A very useful way of comparing data is to draw a bar graph. Sometimes called a bar chart
Used to show the quantity of each of the items being investigated
Eg. Suppose you were investigating how long it took different model cars to travel down a wooden ramp. Results;

Sometimes you want to show the relationship between two things being measured
In this case you would draw a line graph of the data
For example, a group of students was investigating the growth of seedlings. They measured the height of the seedlings every day.

Summary of results you have obtained
Identify any patterns, trends or relationships in the data
Explain results and relationship using scientific principles
E.g. What is the science explanation for why the results turned out the way they did

Evaluation:

Comment on accuracy of materials used in experiment and method used.
Suggest improvements in method and equipment

Conclusion:

What relationship did you find between your IV and DP and was it what you predicted in your hypothesis
