Procedure Writing 101

     Today we practiced writing a procedure from an investigative question.  It was difficult for most and not perfected by many.  The key things to include are: gather materials, record data, multiple trials, independent variable, dependent variable, controlled variable, logical numbered steps.  You must test each value for your independent variable 3 times.  So, you would end up doing three different values for your independent value, thus 3 times 3 is 9 total trials.  

Below is an example of a procedure written correctly.  It is written from the investigative question:  How does the volume of the wood affect its density?

1. Gather materials.
2. Using a metric ruler, measure the volume of the small piece of Cherry wood. (cm3)
3. Record volume.
4. Using a digital scale, measure the mass of the small piece of Cherry wood. (g)
5. Record mass.
6. Calculate density.  (d=m/v)
7. Record data onto data table.
8. Repeat steps 2-7 two more times.
9. Repeat steps 2-8 with medium piece of Oak wood.

10. Repeat steps 2-8 with large piece of Bubinga wood.  

Procedure Writing

     Today we learned how to write procedures in class.  In order to write a procedure correctly, the following need to be included: independent variable, dependent variable, controlled variables, clear numbered steps, the phrase "record data", the phrase "gather materials", multiple trials.  That is it!

From this point on, we will be writing our very own procedures before we do labs.  Like anything, it's hard at first but with practice, it gets easier each time.

Below is a form in which to complete to write your own procedure.

How to Write an Investigative Question

For anyone struggling with the format of how to write an investigative question in the proper format, here it is:

                        How does (independent variable) affect the (dependent variable)?

Remember the independent variable is what you would change, the dependent variable is what you measure.

Hypothesis Writing

     Today we learned to write hypotheses.  You can watch the Hypothesis Rap at the following link:Hypothesis Rap

     Hypotheses are scored solely based on format and that all key parts are included, not based on results of your data. The proper format would look like this:

If (independent variable) increases/decreases then (dependent variable) will increase/decrease/stay the same because (logical reason that supports your statement.
