What is the Scientific Method?

• Scientific Method- step by step process to solve a problem or find out information.

• There are 7 steps of the scientific method…

#1Identify Problem

• Step 1: Identify the Problem

•State the Idea/Topic

• Step 2: Research– Gather Information about the topic

“Why is it important for scientists to research before performing an experiment?”

#2

Research

#3Hypothesis

•Step 3: HypothesisA Hypothesis is an “educated guess”State a possible answer Should always be written:

“I think _______ … because …”

#4Experiment

Step 4: Experiment(Test your Hypothesis)

– Design and Do• List Materials• Identify one “Controlled Variable” in

Experiment – Remains the same throughout experiment.

• Identify “Variables” in Experiment– Independent Variables– Dependent Variables-

• Step 5: Observations and Record Dataa. Data is the information you find or

observe

2 Types of Data…

b. Qualitative datac. Quantitative data

#5Observations &

Record Data

Step 6: Organize and Analyze Data – Create graphs, tables, charts, and

diagrams to organize data.

#6Organize Analyze Data

#7Conclusion

Step 7: Conclusion

– Conclusion is a summary that explains the data, and proves whether the hypothesis was ACCEPTED or REJECTED!

– Does your data support your Hypothesis?

Lab Activity• Do you ever wonder why all

bubbles are different?

During Lab, we are going to follow the scientific method in creating an experiment involving bubbles.

State the Problem• Problem:

“What is the best solution for making the BIGGEST bubble?”

- What do we do after we state our problem?

Homework Tonight • Tonight you are going to research
