Please find the detailedly explained steps below
Step-by-step explanation:
Scientific investigation involves the use of the SCIENTIFIC METHOD, which involves series of steps including:
- Making an observation/Asking a question
- Formulating a hypothesis
- Testing the hypothesis
- Analysing the result
- Conclusion
1) Making an observation/Asking a question: An observation is initially made prior to any investigation. In this case, the observation is whether plants need water to survive. A scientific question can be asked by saying DO PLANTS NEED WATER TO SURVIVE?
2) Formulating a hypothesis: After a question has been asked or an observation has been made, a HYPOTHESIS, which is a testable explanation given to solve or answer the problem is given. A hypothesis is usually in an IF, THEN format. A hypothesis concerning the observation can go thus: IF plants are not supplied with water, THEN they will not grow.
3) Testing the hypothesis: In order to test the hypothesis, an experiment is conducted. This experiment is set up in such a way that two group of plants are used. One group receives water (experimental group) while the other doesn't receive water (control group). The water is the INDEPENDENT VARIABLE while the plant growth measured is the DEPENDENT VARIABLE.
4) Analysing the result: The results of the experiment are analysed and computed in an organized way that can be comprehended.
5) Conclusion: This is the point where the hypothesis will be accepted or rejected based on the results of the experiment. For example, in this case, if plants that are not supplied with water grows, the hypothesis will be REJECTED.
