The Finale of J.S.S.P

This is the final comment from the members of JSSP. We enjoyed working together to find a good, nonlinear system and we have accomplished the task. We have concluded our write up portion of the project and the blog is now almost completed. We will add a few group pictures, and finish touch ups on the website before handing it in to Mr. Hnidei on Tuesday, May 24th, 2011. We hope that this project helps put some perspective on the real life applications of non-linearity.

The Bacterial Growth Graphs!

Here are the graphs from the experiment: 

Using the Graphical Analysis, the first graph illustrates  the number of bacteria colonies grown v.s. time. The non-linearity reflects a power law relation.

Figure 1.1

This graph shows the log of the (x) values and the (y) values. A line of best fit was taken to show the linearity of the log.

Progress In the Making: A quick update Day One to Day Three

This observation was made after 24 hours and it has shown that there was bacteria colonies in both petri dishes. 

The second day, the colonies developed but none of them were very clear of how much was growing. But certainly there were fresh ones that were on their way of producing.

Different kinds of colonies were starting to take part in life. So basically there appeared to be two different kinds of colonies.  It has shown that very small colonies were starting to form with in both petri dishes.  
 

Double Colonies Growing

The following image was taken at the 48 hour mark which shows how many colonies have formed. The colonies can look the same but if carefully observed, the colonies that are growing within each other can be seen and this is called double colonies. They grow within each other because sometimes bacteria can find left over nutrients from another colonies and that’s why you see two colonies stuck to each other.

 This image shows double colonies grouped  together

 

A Great View of the Petri Dish

A  petri dish was slowly submerge  into an antibacterial solution. ie. Clorox, Bleach.  This would ensure that the petri dish would have no markings or stains to eliminate error when counting colonies of bacteria.
