Study Notes
The Scientific Method
- The Scientific Method steps are: Observation, Question, Hypothesis, Experiment, Record Results, Analyse Data, Conclusion
- Observations are made of the surrounding environment to identify a problem requiring further investigation
- A question is asked to gain more information about the observation and possible causes of the problem
- A Hypothesis is an educated guess based on research, formulated to explain the problem
- Experiments are conducted to test the hypothesis
- Results from experiments are recorded using graphs, tables, drawings, and descriptions
- Data is analyzed to break it up into parts which assists in understanding results
- A Conclusion is a summary of the experiment highlighting whether results supported the hypothesis
Working like a scientist
- Fair tests focus on changing one factor at a time, keeping the other factors consistent
- This helps to isolate the effect of the manipulated factor on the outcome
Investigating Plant Growth
- The problem being investigated is to determine whether light is needed for plants to grow
- An experiment is conducted using four boxes with plants inside which are exposed to varying conditions of light and air
- All boxes have holes at the top
- Boxes B, C, and D have an air inlet
- To improve the experiment, additional tests could be made using boxes with no air inlet to investigate the effect of light and air on plant growth
- The experiment could also include a box with a plant that has access to food but no light to determine whether light plays a role in the plant's growth and survival
