Transcript of Overview of the Scientific Method

Has to be
Uses correct lay out
and terminology - for example:

"If ____ (I do this) _____, then _____
(this) _____ will happen because _____."

You must state your hypothesis in a way that
you can easily measure, and of course, your hypothesis should be constructed in a way to
help you answer your original question.

Responding / Dependent
How that ONE thing reacts to being manipulated. The results
of your experiment. You may have more than one reaction.
Things that you do NOT change during an experiment. These MUST remain the
same - you are testing only one variable.

NOTE - There may be more than one.
To complete your science fair project you will communicate your results to others in a final report and a display board. Professional scientists do the same thing by publishing their final report in a scientific journal or by presenting their results on a poster
at a scientific meeting.
(We do Science Fair!)
Ask a Question
The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? And, in order for the scientific method to answer the question it must be about something that you can measure, preferably with a number.
Background research: Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and internet research to help you find the best way to do things and insure that you don't repeat mistakes from the past.

There are three variables that you have to learn and use correctly.
Your experiment tests whether your hypothesis is true or false. It is important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one variable at a time while keeping all other conditions the same (constant).
The Experiment
Manipulated / Independent Variable

This is the ONE thing that you do change in your experiment. You only manipulate one variable at a time.
Must be detailed and specific. Sizes and amounts must be shown.
(Remember Metric Units only)
Material List
Control / Constant Variables
You should repeat your experiment a minimum of three times (three trials) to make sure that the first results weren't just an accident.
Write step by step instructions so that
others can repeat your experiment exactly
the same way using the same procedures and measurements.
Remember all measurements must be made and recorded in metric units only. This is because all scientists around the world use this measurement unit.
Measurement Units
Scientific Notebook: As you work on your experiment write down your observations using academic language. Remember to date all entries into your science notebook. You can include drawings / sketches to help your readers understand what is happening/happened with your experiment.
Create a data collection chart that goes with your experiment. Again, remember all data is collected in metric measurement units.
Illustrations / Models
Data Collection
Illustrations / models can help you and others understand the experiments procedures / data easier.
Models: Draw (2D) or create (3D) models to display information.
Take photographs to show steps taken or the results of the experiment.
Use graphics where necessary if they help explain the results / experiment
Choose a graph that matches your data:

Bar Graph: snapshot in time

Double Bar Graph: compare two similar sets of data on ONE bar graph

Line Graph: changes over time

Independent Variable on the left - vertical or Y axis. Dependent Variable on the horizontal or X axis. Don't forget to label and title your graphs

You can build your graph in Excell - follow this link:

Now we have to
write the
abstract- but that will be another presentation for another day!
Good Scientists
Good scientists keep notebook about everything that they find interesting. This can be anything - space, bugs, force etc.
Once your experiment is complete, collect your measurements and analyze them to see if your hypothesis is true or false. Scientists often find that their hypothesis was false. They will then construct a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again in a new way.

The End
(for now!)


Copy and paste the link below. Search
for scientific inquiry vocabulary for 6th grade, copy down the list. Use the program to discover the meaning and learn how to spell the scientific inquiry words correctly - then use them when you write about your experiment!
Somewhere on your display board you will need to state why you chose to do this project. Tell your audience how your experiment will benefit the world.
