Do Now https://www.youtube.com/watch?v=hKoB0MHVBvM https://www.youtube.com/watch?v=hKoB0MHVBvM In one sentence, summarize the video. What idea is being put forth in the video? If you could ask the two Scientist a question, What would it be? 2

Essential Question How can the scientific method be used to answer testable questions? __________________________________________ __________________________________________ __________________________________________ __________________________________________ __________________________________________ 3

Vocabulary Scientific method testable question non-testable question hypothesis variable control group 4

Pretest: What are the steps to the scientific method. List them below. 5

Steps of the Scientific Method 1.State the problem in the form of a testable question. 2.Research and gather information. 3.Form a hypothesis. 4.Perform an experiment. 5.Collect and analyze data. 6.Draw conclusions. 6

What is the scientific method? 1.It is a __________ __________ scientists use to conduct an __________. 2.It is a way to __________ & __________ scientific questions by __________ questions & conducting __________. 7

1. __________ / __________ 1.State the __________ in the form of a testable question. 2.Ask a __________ about something __________. – Why? – How? – What? 3. Develop a question that is __________ or that can be __________. 8

What is a “__________ __________ ?” 1.A testable question is one that can be answerer by __________ and __________ an experiment. 2.Testable questions are always about changing __________ __________ to see what the effect is on __________ __________. 9 Testable Question Formats Does changing _______ affect _______? How does changing _____ affect _____? If I change ______ will it affect ______? independent variable independent variable independent variable dependent variable dependent variable dependent variable

__________ 1.A __________ is something that can __________. 2.__________ Variable: The variable that will changed by you- the scientist. A good experiment only has one independent variable. 3.__________ Variable: The variable that is being __________ in your experiment. The __________ or __________ to the change you make using the independent variable. 10

Example: Does changing the height of the ramp affect the speed of the car going down the ramp? 11 What is the independent variable? Does changing the __________ of the ramp affect the speed of the car going down the ramp? What is the dependent variable? Does changing the height of the ramp affect the __________ of the car going down the ramp?

Another Testable Question Does changing the amount of light affect the growth rate of plants? Identify the INDEPENDENT variable Identify the DEPENDENT variable __________ 12 __________

Is this a Testable Question? Why or Why not? What makes plants grow best? 13 How to Turn a General Question into a Testable Question 1.Think of a __________ and an __________ related to your question. 2.In this case, the idea is that you can change something to affect something about how a plant grows. 3.__________ are all the __________ in your experiment that you want to remain __________. “What is the effect of soil type on plant height?” Controls for the plant experiment: type of plant growing conditions (sunlight, temperature, etc.) amount of water type of container

2. __________ / __________ __________ Make __________. Find out as much as you can about the __________. 14

3. __________ 1.__________ __________ about how things work. 2.__________ that can be __________ in an experiment. 3.Use If, then statements – If ____ [I do this], then _____ [this will happen] IMPORTANT- Focus on __________ variable only. 15

4. __________ 1.A carefully designed __________ to test your hypothesis. 2.Change only one __________ at a time. 3.Use a __________ or control group. One group must not be changed. 4.In order for results to be __________, conduct __________ tests. 5.Carefully collect observations and __________ your data in a __________ table. 16

5. Experiment __________ __________. – Numerical (__________ ) data organized in rows and columns – The specific independent variables are listed – The number of trials are listed – Blanks are left for the data (dependent variable) to be filled in 17 TrialVariable 1Variable 2Variable 3 1 2 3 4 5 6 AVERAGE

5. __________ and __________ __________ 1.What can your data tell you? 2.__________ __________ or __________ a. Graph the data to look for __________ & __________. 3.Use the __________ and the mean to compare data between two groups. 18

6. __________ 1.__________ of your experiment. 2.Use your data analysis to decide if your observations either __________ or do not support your __________. 3.If your data does not support your hypothesis, give possible __________ to explain this. 4.How could you __________ your experiment with what you have learned? How could you __________ your experiment? 19

Discuss With a shoulder partner, discuss why scientists use the scientific method. 20
