Wood Density Lab

           Today we went over how to complete a Scientific Investigative Plan properly.  All formatting issues and/or definitions are in parenthesis for your use.  We also learned how to fill out our data table in order to record our data accurately.  The first column of the data table is reserved for your independent variable and all the others are reserved for your dependent variables.  In today's and tomorrow's investigation we will be testing the question "How does the volume of the wood affect the density?"  once complete, we will graph our data and write conclusions based on them so stay tuned!  

Below is a link to the Investigative Plan used in class today and a link for the homework handed out.

* If you are struggling with variables, you can watch the Variables Song located to the left under the Videos tab.

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.

Welcome to the blog!

So, I've been encouraged to do a blog!  I had some thoughts about starting a web page but I'm web page illiterate and too cheap to buy a domain name, etc.  I want to be able to make what we are doing in the classroom accessible to parents and students as well!  I'm excited to get started.  Stay tuned, it'll only get better!
