Section 1 – Keywords
Hypothesis - A proposal intended to explain certain facts or observations
Independent Variable – What you change
Dependent Variable – What you measure
Control Variable – What you keep the same
Risk Assessment – Judging whether there are any hazards, what the risk of them is and what safety precautions can reduce them
Hazard – Something with the potential to cause harm
Risk – The chance that the hazard may cause harm to people
Safety Precaution – A process to minimise the risk of a hazard
Method - Step by step instructions for how to complete an experiment.
Results Table – Data recorded from your experiment of the values of the dependent variables as you change the independent variable.
Graph - A visual representation of the relationship between the independent and dependent variables.
Conclusion - summarises how your results support or contradict your original hypothesis

Working Scientifically

3. Section 5 – How to use a Bunsen burner Section 6 – Chemical Reactions
Every chemical reaction has 3 parts:
Reactants  Products
Test for oxygen: A glowing wooden splint will relight. Test for carbon dioxide: Causes limewater to turn cloudy.
Test for hydrogen: A light splint will make a popping sound.
Endothermic – Takes energy in from the environment
Exothermic – Releases energy to the environment
Solvent – a liquid able to dissolve a solute
Solute – the solid dissolved in a solvent
Solution - a liquid mixture of a solute dissolved in a solvent.
Section 7 – A model results table
Every results table should be drawn with a pencil and ruler and include correct headings, correct units, and a mean column.
Section 8 – Model Graph
Every graph should include: axes drawn with a pencil and ruler and then labelled (independent variable on the x axis, dependent variable on the y axis); equal scale with units of measurement (2,4,6,8,10 NOT 2, 8, 12, 13, 16) a line of best fit (if it is a line graph) and finally, a title.
