Scientific Method

Answer 1

• Used to find solutions to problems.
• Steps to be followed
• Continuous process.

Question 2

1. Identifying the problem

Answer 2

• Make observations
• Asks questions

Question 3

2. Formulating the Hypothesis

Answer 3

• Hypothesis: prediction — possible answer to a problem
• Written in “if-then” statements
• Based on prior knowledge — background research is needed

Question 4

3. Testing the Hypothesis

Answer 4

• Variables identified:
  (❗️REMINDER❗️ anything you can change)

1. Independent variable
   CHANGED in the experiment.
2. Dependent variable
   AFFECTED in the experiment
3. Controlled variable

Question 5

Designing an experiment

Answer 5

• Two groups/set-ups

1. Experimental set-up
   - Independent variable/ change will be applied

2 Control set-up
- Use as a standard for comparison

Question 6

FAIR TEST

Answer 6

• Only one variable at a time should be changed (Independent Variable) while other conditions must be kept the same. (controlled variable)

Question 7

4. Gathering and analyzing data

Answer 7

• Collect the results of the experiment.
• Organize them using graphs and tables.

✔️ Patterns and trends.
✔️ Terms Increasing, decreasing, constant, higher, lower.

Question 8

5. Drawing conclusions

Answer 8

• RETURN to problem/question
• Check wether hypothesis is correct or incorrect according to experiment results

Question 9

6. Communicating Results

Answer 9

• For correct or incorrect hypothesis
• Share findings and provide recommendations for future investigations
• Written report, oral reports, online publications
