PRACTICAL SKILLS
SCIENTIFIC METHOD
Aim
Do not use 'iflwhen'
lnclude variables
To prove. . ./ to test. ..
Hypothesis
Educated, predictive statement
lnclude variables
Control variables
These ensure a fair test
Excludes independent variables
Method
Point form or number (read the instructions)
Apparatus included (e.9. permanent marker to write A,B and C on test tubes)
Logical flow
No personal pronouns
Include risk factors
'repeat experiment to gain an accurate average'
'record results in the form of a table'
Must have control experiment (no independent variable)
R/SKFACTORS
- G/assware handled carefully
- Iongs used for hot glassware
, - Chipped or cracked glassware never used
- Never leave a naked flame
- Where a lab coat and gloves
Conclusion
Hypothesis true or false (ilfalse, one can say the hypothesis is unsatisfactory and
therefore must be modified)
Refer to exact table results
DEFINITIONS
what you change
what changes and you measure
something that remains the same throughout
Ir only the independent variable changes and everything else remains
constant
second experiment to provide suitable comparison
I, if repeated one will get the same results
I, only independent variable is not constant
Measuring
Ir cbse to the true value
I, smallest scale on measuring apparatus
Quantitative: measurable and objective
I' involves open-minded responses and subjective (e.g. colors)
