4. To learn more about the world Scientist use Scientific Inquiry: • Observe • Form Hypothesis • Predicting • Test • Analyze Results • Draw Conclusions • Communicate Results

5. Observing

6. Observing • Observing means using one or more of your senses to gather information. • Quantitative observation: deal with a number, or amount • Qualitative observation: deal with descriptions that can not be expressed with numbers.

7. Inferring

8. Inferring • When you go beyond observing and reason why something happen. • When you explain or interpret the things you observe. • You are not guessing wildly, but rather you are making a guess based on what you know should or shouldn’t happen.

9. Predicting

10. Predicting • Making a statement of what will happen next in a sequence of events based on past experience or evidence. • Predictions, of course, are not always correct. • Predictions and inferences are closely related.

11. Inference is typically an attempt to explain what is happening or has happened. • A prediction is a forecast of what will happen next.

12. Infer how this might have happen. Predict what will happen next.

13. Hypothesis • After you make your observations and inferences, you are ready to develop a hypothesis and begin your investigation. • A hypothesis is a possible explanation about an observation that can be tested by scientific investigation. Hypothesis: Eggs are fragile and will break when dropped onto a hard surface.

14. Test your Hypothesis • When you test a hypothesis, you often are testing your predictions. • If your prediction is confirmed, it supports your hypothesis. • If your prediction is not confirmed, your hypothesis might need to revised.

15. Analyze • Keep good notes, take pictures, record all important information! • You can create graphs, classify information, or make models. • Once your data is organized, you can study your results and come to some sort of conclusion.

16. Classifying

17. Classifying • Classifying is the process of grouping together items that are alike in some way. • It is a way to organize things into some type of order.

18. Making models

19. Making models • Making models involves creating representations of complex objects or processes. • Models help you observe the unobservable. • They are only a representation of the real object or process. Some information could be missing, therefore you can not learn everything from a model.

20. Conclusion • Now you must decide whether your data do or do not support our hypothesis. • ARE YOU RIGHT OR WRONG? • A conclusion is a summary of the information gained from testing a hypothesis. • You need to explain why you are right or what is wrong with your original hypothesis.
