Use quizlet!
What is the law of conservation of mass?
Total mass of reactants is equal to the total mass of products
Why is this, Total mass of reactants is equal to the total mass of products (conservation of mass)?
In reactions atoms cannot be created or destroyed they are simply rearranged
SAY EVERY SINGLE PEICE OF EQUIPMENT IN FILTRATION AND HOW IT WORKS.
Filter paper, Beaker, Mixture, Residue, Filter funnel, Conical flask, Filtrate
Liquid particles are small enough to pass through filter paper
Solid particles are to large to pass through filter paper and so stay behind

2.This is made by dissolving a solid in water
What does Soluble mean?
A solid that does dissolve in water
What does Insoluble mean?
A solid that does not dissolve in water
What does Solute mean?
The solid dissolved in water
What does Solvent mean?
The water in a solution
What does the Solution mean?
This is made by dissolving a solid in water
SAY EVERY SINGLE PEICE OF EQUIPMENT IN SIMPLE DISTILATION AND HOW IT WORKS.
Thermometer, Liebeg condenser, Round bottom flask, Solution, Water out, Water in, Heat source, Distillate
Simple distilation is a physical method which is used to separate a liquid from a soluble solid in a solution
Simple distilation works because the dissolved solute and solvent have very different boiling points
There are two main processes that happen during simple distillation;
Boiling/evaporation (liquid to gas)
Condesation (gas to liquid)
Extra information:
Example, producing pure water from salty sea water solution
SAY EVERY SINGLE PEICE OF EQUIPMENT IN CHROMATOGRAPHY AND HOW IT WORKS.
Lid, Beaker, Chromatography paper, Start line drawn with pencil, Solvent
Chromatography is a separating technique used to separate mixtures of soluble substances
As the solvent travels up the chromatography paper, the different substances in mixture travel different distance depending on their solubility/solubilities
The more soluble the substances, the further it travels
The mixture to be separated must be soluble in the solvent

Examples, dyes, colours in foods
Earth’s structure: Revise from 3rd Science book
!!Make flashcards if you need to!!
Earth’s resources: What are the three groups of rocks?
Sedimentary rocks, Igneous rocks, Metamorphic rocks
Earth’s resources: Sedimentary rocks; These are formed from layers of ……….., and which can contain ……….
Sediment, fossils
Earth’s resources: Sedimentary rocks; Sediments are ………. particles which settle out from slow moving ………. in rivers, lakes or …………
Small, water, oceans
Earth’s resources: Sedimentary rocks; Over time the layers of ………. are cemented together and ……….. the ………. above it
Sediments, compressed, weight
Earth’s resources: Sedimentary rocks; ………. can be found in sedimentary rocks
Fossils
Earth’s resources: Sedimentary rocks; Fossils are formed from the ………. parts of an ……… (shell or skeleton) are trapped in …………when it turns into rocks
Hard, animals, sediments
Earth’s resources: Sedimentary rocks; Over time, the shell or skeleton is replaced with ………., which become the ………..
Minerals, fossils
Earth’s resources: Sedimentary rocks; Observation of sedimentary rocks: What are a visable observation of sedimentary rocks?
They often have visable layers called strata
Earth’s resources: Sedimentary rocks; Observation of sedimentary rocks: What are examples of sedimentary rocks?
Limestone (used for contrsuction), Chalk (light), Sandstone
Earth’s resources: Igneous rocks; What is magma?
Molten rock found BELOW the earths surfaces/layers
Earth’s resources: Igneous rocks; What is lava?
Molten rock found ON/ABOVE the SURFACE of the earth when the volcano erupts
Earth’s resources: Igneous rocks; How are Igneous rock formed?
Formed from magma or lava
Earth’s resources: Igneous rocks; What do igneous rocks contain?
Contain minerals in randomly arranged interlocking crystals
Earth’s resources: Igneous rocks; What do the minerals in randomly arranged interlocking crystals size depend on?
Size of the crystals depends on the speed of cooling
Earth’s resources: Igneous rocks; Speed of cooling! What forms because of the speed of cooling?
Large crystals mean the rock has slowly cooled under the surface of the earth (Intrusive) - igneous rock
Earth’s resources: Igneous rocks; Speed of cooling! What forms because of the speed of cooling?
Small crystals mean the rock has quickly cooled above the surface of the earth (Extrusive) - igneous rock
Earth’s resources: Igneous rocks; what are some examples of extrusive and intrusive Igneous rocks?
Basalt - Extrusive
Obsidian- Extrusive
Granite- Intrusive
Earth’s resources: How are metamorphic rocks formed?
Formed from existing sedimentary rocks or igneous rock placed under high temperature and pressure over a long period of time
Earth’s resources: What tends to be different about metamorphic rocks compared to the other types of rocks?
Tend to be harder and resistant to erosion which is why they are used in flooring and workshops
Earth’s resources: What are examples of metamorphic rocks?
Marble, slate, schist, (skiddaw)
