Hello Come on in…. What do you bring to your seat… Notebook Academic Organizer Pen, pencil, writing utensil
Warm up 1. What two things must be at the top of every page in your notebook? 2. Why do you need to bring your science notebook everyday? 3. Do you write on every slide that is up on the screen? 4. How do you set your paper up for Cornell notes?
What is the scientific method? A systematic approach to problem solving. A method that is applied in all scientific investigations. USE: LABS & EXPERIMENTS
What is the Scientific Method Systematic approach to solving a problem Used for labs and scientific experiments
Steps to the Scientific Method State the problem. (Purpose) Gather information on the problem. (Research) Form a hypothesis. Perform experiment(s) to test the hypothesis. Record and analyze data. State a conclusion.
Steps Purpose ( problem) Research Hypothesis ( educated guess about outcome) Experiment Analysis Conclusion
State the Problem This is the purpose of the investigation. State what problem you want to solve or what question you want to answer.
problem Purpose Usually a Question State (write the problem you are trying to solve)
Gather Information (Research) Use various resources to inform yourself about the parts of your investigation. This involves research!! You must educate yourself about your investigation so that you can make an “educated guess” to test.
research Gathering information about your topic to be able to form a hypothesis
Develop a Hypothesis A hypothesis is an educated guess proposes an answer to your question or a solution to your problem. The hypothesis is what you are testing in an investigation. Let’s choose an example and work through the first three steps of the scientific method together.
Hypothesis Educated guess on what the outcome of your problem (question) is going to be
Warm Up 1. What are the two things you should have at the top of each page? 2. What goes on the bottom of the last page of your notes? 3. What is the definition of the Scientific method? 4. What does hypothesis mean? 5. What are the steps of the scientific method in order?
Prepare for day 2 Cornell notes SCIENTIFIC METHOD
Let’s Try My car wont start…. What’s the problem? How can we gather information about the problem? What are some possible hypotheses we could investigate?
Perform the experiment Design and perform an experiment that will test your hypothesis for accuracy. To do this you must be able to identify your variables.
Experiment Actually performing the lab or experiment to test your hypothesis to see if it is true or false Includes variables
Variables Manipulated- the thing being changed throughout the experiment Responding- the thing being measured Controlled- t he thing that stays the same
Variables Manipulated- the thing being changed in the experiment Responding- the thing you are measuring Controlled- the things that stay the same
Back to the Car…. Possible hypothesis: If gas is put into the car, the car will start. What’s the manipulated variable? What are some controlled variables? What is the responding variable?
Record and Analyze Data Data includes the measurements and/or observations you make about the responding variable. But first, you must determine what type of data (called observations) you will collect.
State the Conclusion Your conclusions should consist of your best explanations for given observations. Your conclusion should answer the questions: What happened? and Why did it happen?
Analysis Conclusion Observations linked to the responding variable Recorded data (charts, graphs, measurements) Summary of what happened and why
Let’s Try again: Does sunlight affect plant growth? Purpose ( what is the problem ) Research ( where are going to go for research) Hypothesis ( what your educated guess is) Experiment ( list 3 Variables) Analysis ( tell me what you observed) Conclusion ( tell me if your hypothesis was correct or false and why? )
