Presentation Transcript
Warm up
• Suppose someone told you that 1 pound of feathers was heavier than 1 pound of gold.
• How would you prove them wrong?
• What equipment would you need to show them that they were incorrect?

### Scientific Method

What is the Scientific Method?
• A series of steps that scientists use to answer questions and solve problems
Step 1 : Ask a Question
• Asking a question helps focus an investigation.
• “Which is heavier?”
Step 2: Research
• In order to test a hypothesis scientist gather data on their question.
• “I know for a fact that feathers are very light.”
Step 3: Form a hypothesis
• A hypothesis is a possible explanation, or answer to a question.
• “I think gold is heavier.”
Step 4: Experiment
• To test a hypothesis scientist conduct a controlled experiment.
• “I will weigh each item on a triple beam balance.”
Make Observations
• Scientist look at the results from their experiments and record the data.
• “I see that a cubic cm of gold is heavier than a cubic cm of feathers.”
Keeping Good Records
• Scientists keep very detailed records for many reasons.
• Prevent opinions from interfering

2. Keep notes for future experiments

3. Communicate with future scientists

Step 5: Draw Conclusions
• After analyzing their results, scientists decide if their results support their hypothesis.
• If the hypothesis is wrong, the scientist will change the hypothesis and repeat the experiment.
Warm up(Use your note from yesterday.)
• Tell what part of the scientific method each scenario fits.
• Is cold air heavier or lighter than hot air?
• I think that a black shirt will make you warmer than a white shirt.
• The professor that I talked to said that inch worms are longer than earth worms.
The Scientific Method
• Question
• Research
• Hypothesis
• Experiment
• Conclusions
The Scientific Method in Action
• Question:
• Which will bounce higher, a bouncy ball or a rubber band ball?
The Scientific Method in Action
• Research
• Which feels softer?
• Which is heavier
• Which is more rubbery?
The Scientific Method in Action
• Hypothesis
• I think the _________________ will bounce higher.
The Scientific Method in Action
• Experiment
• How will I test this hypothesis?
The Scientific Method in Action
• Conclusion
• Which bounced higher?
• Was my hypothesis correct?
