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.

Yes, Idea Approved!

Today our group showed Mr Hnidei our data from the experiment conducted. Showing him the data graph and the log log graph. Our data came out as a power law function. J.S.S.P is very pleased that our idea is working and is now determined to finish the write up portion and the blog.

Somaya Explaining The Experiment

 

 This is a rough demonstration of the experiment.

Experiment On The Go Again!

The bacteria samples were transferred into the petri dish and was left to grow. Some colonies showed up in the first 24 hours. A couple of days later the results showed that the colonies started to show up and they would varied in size. Finally, the experiment went through the week and the data was recorded. Some pictures and videos were taken each day to show the progess of the bacteria growth experiment. Our group took some great pictures and videos.

Restarting Experiment

Today we have consulted Mr. Hnidei about our bacteria growth experiment. He seems to have noticed a slight disparity in the graph. Since the graph was found insufficient we have decided to rerun the experiment. This time making sure to take data with in the first 24 hours of beginning the experiment. This time we have clean data and it seems to have made a better graph. We have reason to believe that the first experiment was run incorrectly between 2 petri dishes. The experiment was compromised due to unsterilized petri dishes.

Our Group In The Beginning Of J.S.S.P

So our group for this non-linear system is made up of John, Paul, Somaya, and Steve . We have a few ideas that we are exploring for this project and having a hard time choosing one solid system. We are hoping to get started A.S.A.P on our experiment.

FSE Project

Our idea for a nonlinear system is to find out how much bacteria  can grow with in a week. We're hoping this will be a nice and consistent system and our data shows to be one of  following: a root function, an inverse law, or a power law.
