Learn about the 6 major steps of the scientific method, including hypothesis development, experiment design, data recording, and conclusion making.
E N D
Warm Up – Aug. 28, 2018 ObjectiveCopy the following: I can verbally describe the 6 major steps of the scientific method. Do NowAnswer using complete sentences: 1) Give your best definition of a hypothesis. 2) You are conducting an experiment to determine if ants dig more tunnels when exposed to daylight. Write a hypothesis for this scenario (in if..then.. format if you have learned it).
Warm Up, cont’d – Aug. 28 , 2018 Homework: • Study for Prefixes/Suffixes Quiz (words 1-20) – Will be Thurs. 8/30 Agenda: -Finish/Debrief Mystery Boxes -Notes: The Scientific Method Objective: I can verbally describe the 6 major steps of the scientific method.
What is the Scientific Method? • It refers to the steps someone takes to… • Identify a question • Develop a hypothesis (educated guess) • Design an experiment • Record observations • Make a conclusion In other words.. it’s a way to solve a problem!
Scientists think carefully and logically when they…(1) investigate a question or problem. Ex: What is in this box?
Scientists develop a question, gather information and…(2) form a hypothesis-- an educated guess. Ex: If the object inside the box is bouncy and rolls around, then it is a superball.
Writing a Scientific Hypothesis: If…, Then… Ex: If the check is for Auto Body Shop, then she went to go fix her car.
The next step scientists take is to…(3) create and conduct an experimentto test their hypothesis. Ex: Move the box side to side to see if the object is rolling or sliding.
A key to experiments is…(4) observing what happens and writing it down. Ex:
(4a) QuaLitative Observations are based on Looks! Note: There are 2 types of observations! Color, shape, size, texture can be used to make observations. Ex: The ball is small and rubbery.
(4b) QuaNtitative Observations are based on Numbers! Make these observations by counting or measuring with a tool (ruler, scale, etc.). Ex: The metal pipe weighs 5 grams. Ex: There are 12 checks.
Make 1 quaLitative observation and 1 quaNtitative observation:
Note: Gathering information or data and recording it so it is readable and makes sense to others is really important. Don’t be a mad scientist!!
Once a scientist completes an experiment, they will…(5) repeat the experiment to see if they get the same results. This is called verification-- checking things out to make sure everything was correct and the results will be the same over and over.
Scientists also need to…(6) share their experiments and conclusions with others. Because they share their experiments and findings, scientists can learn from each other and often use someone else’s experiences to help them with what they are studying or doing.
The steps of the Scientific Method are: • Question • Background Research • Hypothesis • Procedure (Experiment) • Data (Observations) • Conclusion
Graphing Preassessment! Directions: Create a line graph based on the data table. Include all elements of a proper graph. You will be given 8 minutes.
Warm Up – Aug 29, 2018 ObjectiveCopy the following: I can identify in writing the variables and treatment groups of a scientific experiment. Do NowAnswer using complete sentences: 1) List the steps of the scientific method (complete sentences not necessary). 2a) Choose one step and circle it. 2b) Explain what that step you circled contributes to the experimental process. OR Explain how you used this step in our Mystery Boxes activity.
Warm Up, cont’d – Aug 29, 2018 Homework: • Get Student Safety Contract signed – Due Friday 8/31 • STUDY!! Prefixes/Suffixes Quiz (words 1-20) – Will be tomorrow, Thurs. 8/30 Agenda:- Reminder: Office Hours Today!! - Finish Notes: Sci Method - A Variable Way to Practice Variables - Graphing PreAssessment? Objective: I can identify in writing the variables and treatment groups of a scientific experiment.
Independent Variable: CHANGED the 1 variable that is ___________ in an experiment Dependent Variable: MEASURED the 1 variable that is ______________ in an experiment
The Title is Always… The Effect of ____________on ___________ Independent Dependent The Effect of ______________ on ______________ SOIL TYPE PLANT HEIGHT
Experimental And Control Groups In order to test something, we must have a comparison. - Experimental group: one being tested - Control group: comparison to the experimental group
Experimental And Control Groups In an experimental and control group, only the independent variable is changed. Medicine example - clinical trials (placebo)

Exercise #1 Maria wanted to start exercising and went to Footlocker to get some running shoes. She saw an advertisement that claimed to perform twice as well as any other running shoes. She wants to test this claim. • What does she want to test? • What should she change? • What should she measure? • What should stay constant?
Exercise #2 John was told that an insurance company claims that red cars are safer than other cars. He wants to find out if this is true. • What does he want to test? • What should he change? • What should he measure? • What should stay constant?
Practice WS: A Variable Way to Practice Variables.. • Work either alone or with a partner • Use binder p. 9 or a textbook to help answer questions to the best of your ability! • Extension: Design your own experiment and have a friend identify hypothesis, independent, and dependent variables
Warm Up – Aug 30, 2018 ObjectiveCopy the following: I can identify in writing the variables and treatment groups in an experiment I will be performing. DO-NOW: (complete sentences) USE p. 9!!! Jasmine believes that mice gain more weight when on a high-fat diet. She set up an experiment where 20 mice are kept on different diets for 4 weeks. After 4 weeks, she recorded their weight gain. 1. What is the independent variable (changed)? 2. What is the dependent variable (measured)? 3. What needs to stay constant?
