3. hypothesis question Scientists use experiments to test a hypothesis or answer a question

4. Parts of an Experiment ASK A QUESTION What question is being answered, problem solved, or hypothesis tested. Leads to observations For example, “How many drops of water fit on a penny?”

5. Form a Hypothesis An educated guess about the results. Based on observations & can be tested!!! Always support your idea with a reason! (I think that…because…) Write yours down!What is your hypothesis about the number of water drops that can fit on a penny? Write yours down! Make a prediction with an if-then statement –Example: ________________________ Parts of an Experiment

6. Materials: Items used during the experiment. What would we need for the penny experiment? Write yours down… Parts of an Experiment

7. Procedures Procedures: Steps followed during experiment. –Write in a numbered list –Should be detailed enough that anyone can follow exactly what you did. –How many times you are going to do the experiment? It should be written here! Parts of an Experiment

8. Practice Work with your tablemate to practice writing out a procedure for testing the penny experiment Be specific!

9. Collecting Data: All the information gathered while performing the experiment. Parts of an Experiment

10. Analyze the Results & Draw Conclusions: Analyze your data to determine the final outcome of the experiment What do you NOW believe as a result of the experiment or observations? Restate your hypothesis (or at least relate your findings to it) Support your claim with at least 2 pieces of data and graphs Use good explanatory language Parts of an Experiment

11. Practice Conclusion Write oneWhat should our conclusion be about how many drops of water a penny can hold? Write one for your experiment, using the above guidelines:

12. Share your results: Publish your findings so that others may benefit from your work. Parts of an Experiment

14. There are two groups in a controlled experiment: Control Group 1) Control Group: the part of the experiment that is left alone or “natural”. Used to compare back to.

15. There are two groups in a controlled experiment: Experimental Group: 2) Experimental Group: the part of the experiment in which a factor or variable is changed.

16. Variables are parts of an experiment

17. Control (constant variables): NOT factors in an experiment that are NOT changed.

18. Independent (manipulated) Variable: changed factors in an experiment that are changed. ONEGood experiments have only ONE manipulated variable.

19. Dependent Variable Dependent (responding) Variable: measuring the factor that you are measuring.

20. explanation hypotheses observations An explanation that ties together many hypotheses and observations Example: Theory of Evolution

21. experimental resultsobservations A summary of many experimental results and observations that tells how things work True and Universal Example: Law of Gravity, Newton’s Laws

23. Observations Observations: eventsDescription of objects, events May include data from all five senses (touch/texture, smell, taste, sight, sound) Could be drawings, diagrams, written words opinionsDo not include opinions.

24. Inferences conclusionsDrawing conclusions based on observations reasonOften provide a reason for the event/object being observed.

25. hypothesisMore like a scientific law than a hypothesis. Explanation of a set of related observations or events based upon proven hypotheses. multipleVerified multiple times by detached groups of researchers. One scientist cannot create a theory, he/she can only create a hypothesis. The theory of evolution, the theory of relativity, and the quantum theoryExamples: The theory of evolution, the theory of relativity, and the quantum theory.

26. explainA statement of fact meant to explain, in concise terms, an action or set of actions. alwaysGenerally accepted to be true and universal, and can sometimes be expressed in terms of a single mathematical equation. Scientific laws are similar to mathematical postulates. They don’t really need any complex external proofs; they are accepted at face value based upon the fact that they have always been observed to be true. ExamplesThe law of gravity,Examples: The law of gravity, the law of thermodynamicsthe law of thermodynamics.

27. trueBoth a scientific theory and a scientific law are accepted to be true by the scientific community as a whole. predictionsBoth are used to make predictions of events. technologyBoth are used to advance technology.

28. A theory is much more complex and dynamic. actionA law governs a single action, whereas a theory explains a whole series of related phenomena.
