Graphing tips for investigations:
1. Put a title
2. Label both axes including UNITS
3. Plot the AVERAGE of your three trials (repeats)
4. Put the thing you change (independent variable) on the x axis
5. Make sure your scale is regular e.g. goes up in lots of 10 or 5
6. Draw in a ‘line of best fit’ and label it ‘line of best fit’. This is art not Science – try to get an even number of points on each side of the line of best fit
The first 20 elements: (for Chemistry you need to know the symbol that goes with each name)
H - hydrogen He - helium Li - lithium Be - beryllium (I ALWAYS have trouble with this spelling - memory tool "there are no berries in beryllium" ie, only one r)
B - boron C - carbon N - nitrogen O - oxygen F - fluorine (no letter l in the symbol)
Ne - neon Na - sodium Mg - magnesium Al - aluminium
Si - silicon P - phosphorus S - sulphur Cl - chlorine
Ar - argon K - potassium Ca - calcium
Others you need to know:
Pb - lead Ag - silver Au - gold Cu - copper
Co - cobolt Zn - zinc Ni - nicol Fe - iron

Exam tips:
To get Merit or Excellence grades in Science, you need to expand on simple answers, but don't skip the basics.
try this process 'DEL': define, explain, link
define terms
explain in your answer
make links to bigger Science ideas
some examples of bigger Science ideas to link to:
for Genetics: survival of a species, genetic variation within a population, evolution, natural selection, shuffling of genes (which results in greater variation)
for Acids and Bases: valence electron movements, ionic bonding, dissociation (bonds breaking), the octet rule, stability resulting from full valence shell
