The systematic study of natural events and conditions to gain a better understanding of the natural world

3. What is Empirical Evidence?
All of the observations, measurements, and data that scientists gather in support of a scientific explanation

4. Why do scientists need empirical evidence?
To support their claims and to improve our lives such as
Developing new technology
Lessoning human impact on the environment
Creating medicines and curing diseases

5. What are 2 ways scientists can investigate new information?
Observation: gathering information using your senses
Experiment: an organized procedure used to study something under controlled conditions

6. Conducting an experiment
What process do scientists use when conducting an experiment?

7. Conducting an experiment
They use the scientific method!
Step 1: define the problem to answer the question you are trying to answer
Step 2: Form a Hypothesis
A hypothesis is an educated guess/prediction to the problem you’re trying to solve

8. Scientific Method
Step 3: Plan and Conduct an experiment

9. Scientific method Step 4: observe and record data
It is important to be organized when you are collecting data
Step 5: Analyze the data you have collected and make a conclusion

10. Scientific method What should I do wHen making a conclusion?
Restate the hypothesis and the results from the experiment
Include data tables, charts, and graphs

11. Scientific method Step 6: Share your results
Share your results with others and relate your results to the real world

12. Replication vs repetition
Replication is when other scientists conduct the experiment Repetition is when the SAME scientist conducts the experiment multiple times

13. Why is replication important?

14. Why is Repetition Important?
