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

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

  5. Parts of an Experiment Hypothesis An educated guess about the results. • Always support your idea with a reason! (I think that…because…) What are some hypotheses you can come up with about the penny? Write yours down!

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

  7. Parts of an Experiment 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!

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

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

  10. Parts of an Experiment Results/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 • Use good explanatory language

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

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

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

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

  15. What is a Variable? • Variables are parts of an experiment

  16. What is a Variable? Controlled variables (constants): factors in an experiment that are NOT changed.

  17. What is a Variable? • Manipulated (independent) variable: • factors in an experiment that are changed. • Good experiments have only ONE manipulated variable.

  18. What is a Variable? Responding (dependent) variable: the factor that you are measuring.
