We need to build a hypothesis as an initial explanation of the observation or phenomenon being investigated. The hypothesis has to be tested.
Identify the type of variables involved. Variables are physical quantities that influence the observation or scientific phenomena and it consists of manipulated variables, constant variables and responding variables.
We have to design an experiment carefully beforehand. We also need to choose the right materials and apparatus for the experiment.
While conducting the experiment, precautions must be practised at all times to obtain a more accurate data. Safety measures must also be followed to prevent accidents.
Data collection is carried out carefully using suitable instruments while taking into consideration any random or systematic error that might occur. Make sure the measurements are carried out at least three times to obtain a more accurate and precise reading. Use a table to record your data.
- Analyse and interpret data
Analysis must be accompanied by effective communication forms such as graphs and tables. Graphs and tables assist us to easily interpret the data.
Conclusions are made based on experimental analysis; either hypothesis is accepted or rejected. If rejected, we need to make a new hypothesis and carry out the experiment again.
When writing a report, all important data and information must be included.
