The Scientific Inquiry Process
Transcript of The Scientific Inquiry Process
Step 1 : Question
What do you want to know?
What are you trying to solve?
What is the problem?
Step 2 : Research
What do we already know about this?
What information could help us make a more educated experiment?
What work has already been done for us?
Step 3 : Hypothesis
Based on everything you know, what do YOU think will happen?
Step 4 : Test/Experiment
How will you figure out if your hypothesis is right or wrong?
What steps will you take to
test your hypothesis?
What do you need to do to figure out
the answer to your question?
Step 5 : Control/Variable
What will stay the same?
What will change?
How will we make sure that our test results are accurate?
In other words: The Scientific Method
What are the results of your test?
What are the numbers?
What observations have you made?
Step 6 :
Step 7 : Graph
What does all the data mean?
What does it tell us about the question and hypothesis?
What other factors
must be considered?
Step 8 : Analyze
Was your hypothesis correct?
How was it the same or different?
What does all this mean?
Where do you go from here?
What type of graph will
best show the data?
How do we set up the graph?
Step 9 : Revise
Now, make an acronym to help you remember the steps.
It will be a sentence in which each word in the sentence starts with the next step of the scientific method.
for example, to remember the planets:
My Very Excellent Mother Just Served Us Nachos
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
So you will use:
Question, Research, Hypothesis, Test, Control/Variable, Data, Graph, Analyze, Revise
Q_______ R_________ H_________ T________ C_________ D_______ G________ A________ R________
what makes a good
WHY do we begin
with a question?
so that we have an idea of what we want to know and where we are going with our investigation.
3. cannot be answered with yes or no
Can we design a better paper airplane?
1. Is it specific?
2. Is it measurable?
3. Can it be answered with yes or no?
okay, so it does not pass the test...HOW CAN WE MAKE IT BETTER?
Rewrite this question to make it appropriate for a scientific investigation:
Is a guinea pig smarter than a gerbil?
1. specific 2. measurable 3. cannot be answered with yes or no
How do we know if it is
a reliable source?
Why is research important?
What are you suggestions to someone researching for the first time?
- *reputable source*
- pictures/diagrams with good captions
- recent date (within 3 yrs or less)
- includes historical facts as well
- author and location listed
- references credible people
Which of these do you think is the best hypothesis?
I think the guinea pig will get through the maze faster.
How much more quickly can a guinea pig get through a maze than a gerbil?
I think the guinea pig will get through the maze faster because it is cuter.
I think the guinea pig will get through the maze faster because it has a better sense of smell.
I think the gerbil will get through the maze faster because it is smaller.
I think the gerbil will get through the maze faster.
What makes a
1. Make a hypothesis.
2. Sketch a design of your plane.
3. Write an explanation of your design (back it up with RESEARCH!!)
4. Ms Keefer must approve all work and take a picture in order to receive your materials.
*5 pieces of paper
*2 pieces of card stock
*6 large paper clips
*4 small paper clips
*scissors, glue, tape
I think the gerbil will get through the maze faster because studies show that they have excellent way-finding skills.
Write 2-4 sentences in your notebook about today's poster.
What does it mean to you?
What does it mean for this class?
:) Use the proper heading (date & title)
What are you testing?
You are testing your hypothesis. You are testing a possible answer to your original Question!
What do you need to understand and incorporate into your test?
1. The basics. What are the basic steps you will go through?
We will put the gerbil into a maze with food at the end and will use a stop watch to time how long it takes for it to get out.
We will do the same with the guinea pig.
The maze will be made of cardboard and will be large enough that it does not hinder the movement of either animal.
2. The measurements. How will you measure your data?
We will measure the amount of time it takes for each animal to get through the maze in seconds.
3. The details. Be very specific about HOW you will do the experiment. This gives more accurate results.
*We will use the same maze for both animals.
*We will release the animals at the same place in the maze.
*We will start the stop watch as soon as each animal is released.
*We will use the same kind of food at the end of the maze (a piece of apple).
*We will not help either animal as they go through the maze.
*....what else can you think of???
NOW YOU TRY!!!
See prezi entitled: "Copy of Variables"
Write 2-4 sentences in your notebook about today's poster.
BEFORE YOU SPEAK, THINK!
When is a time that you wished you had thought before you spoke? Why? What happened?
We need to collect measurable data as we go, so we can have accurate information.
1. Use a chart to collect information in an organized way.
2. Run your test more than once.
3. Double check your numbers.
4. Find averages.
We want to also consider what we observed while we ran the test, because it helps us better understand WHY the numbers look the way they do.
1. What did you see?
2. Be SPECIFIC!
3. Use descriptive words.
Which is a better observation?
It didn't go far.
It flew straight up into the air and then spiraled downward.
It flew really far really fast.
It flew really quickly and fell gradually toward the ground, continuing to slide after it hit the ground.
Set up your notebook page like this:
Write a short paragraph
(about 4-5 sentences)
about how you did on the midterm.
Were you happy with your grade?
Did you study? How much?
How do you plan to prepare for the next test we have in here? (Unit 1 exam)
Types of Graphs
Research your type of graph.
Write down notes that are important on the purple paper.
Draw an example.
What does it best show?
Where do you put the controls and variables?
Now try it!!!
What kind of graph will you use to graph your paper plane data?
1. Graph your paper plane data in your notebook.
2. Under your graph, write about WHY you chose that type of graph.
When do we use it?
examine methodically and in detail the constitution or structure of something, (especially information), typically for purposes of explanation and interpretation.
How to analyze!
1. What does your graph tell you?
2. Compare the data (how far the plane flew) to your written observations. What do you notice about the planes that did/did not fly far?
3. Look at your paper plane and think about WHY it flew the way it did and traveled the distance it traveled. What about your plane design might have influenced how far it flew? What improvements can you make so it will go even farther?
Answer all questions in complete sentences in your notebook. ALL GROUP MEMBERS should record this in their composition book.
Write 2-3 sentences in your notebook about today's poster.
What does it mean?
Do you agree?
Why or why not?
Now, based on your analysis, how will you re-design your plane to make it better?
