  1. Does Soap Float? We’re going to use The Scientific Method

  2. Scientific Method • Question • Hypothesis • Experiment Materials • Experiment Design • Data • Conclusion

  3. Question: What do you want to know? • Scientists—like the fourth graders in this room—often begin with a question. Then, they conduct an experiment or investigation to find out more information. Our question is: Does soap float?

  4. Scientific Method • Question- Does soap float? • Hypothesis • Experiment Materials • Experiment Design • Data • Conclusion

  5. Hypothesis • A hypothesis is a statement that can be tested. • “I predict if I. . . . Then,. . . • Example of hypothesis, “I predict if I put Lever 2000 soap into water it will sink. I predict Lever 2000 soap will be more dense than water.” • Write one hypothesis next to each type of soap on your recording sheet.

  6. Scientific Method • Question- Does soap float? • Hypothesis- A statement that can be tested. • Experiment Materials • Experiment Design • Data • Conclusion

  7. Experiment Materials • What do you need to conduct your experiment or investigation? • We will need: Four kinds of soap, a large bowl, water and our recording sheets.

  8. Scientific Method • Question- Does soap float? • Hypothesis- A statement that can be tested. • Experiment Materials- 4 kinds of soap, a large bowl, water and our recording sheets • Experiment Design • Data • Conclusion

  9. Experiment Design-Steps of the experiment First, we will fill a bowl with water. Second, we will place one kind of soap into the water and record our observations. Third, we will repeat this experiment three more times using a different type of soap each time.

  10. Scientific Method • Question Does soap float? • Hypothesis A statement that can be tested • Experiment Materials The materials that you need • Experiment Design Steps of the experiment • Data • Conclusion

  11. Data-Information gathered through the experiment • Record data on your observation log. • Data is ANY information that you gather during the experiment.

  12. Scientific Method • Question Does soap float? • Hypothesis A statement that can be tested • Experiment Materials The materials that you need • Experiment Design Steps of the experiment • Data Information gathered • Conclusion

  13. Conclusion • Was your hypothesis proven or disproven? • Example Hypothesis: I predict that Lever 2000 soap will float in water. Conclusion: My hypothesis was proven. Lever 2000 soap does float in water.

  14. Scientific Method • Question Does soap float? • Hypothesis A statement that can be tested • Experiment Materials The materials that you need • Experiment Design Steps of the experiment • Data Information gathered • Conclusion Was your hypothesis proven or disproven?

  15. Thought Question Students in Room A conducted an investigation. They want students in Room B to do the same investigation so that they can compare results. What should the students share with the other class so that the experiment could be repeated? • Materials and experiment design • Conclusions about the results of the investigation • Where they got the idea for the experiment • Hypothesis and data

  16. Keeping Conditions The Same: This means you keep the materials and experiment design the same. Thought Question: When you repeat an experiment, why do you think it is important to keep conditions the same?
