Over the weekend I discovered something really interesting from Antony, my friend's uncle, who has a PhD in science. He told me that all water has bacteria, so it would be a little pointless in counting the colonies of bacteria in my water. But I could find the breathing rate of the bacteria, which would sort of show how much of it is in there, because of this:
For Example: If there are heaps of mice in a jar, and only one mouse in a jar, the jar with a lot of mice will run out of oxygen faster than the jar with only one mouse. This happens because the more living things, the more oxygen consumed. Because of this, I can see which water will run out of oxygen first, which will show which water has more bacteria.
I'll keep the blog up to date with pictures.
Welcome to my Science Log where I will show you how I am doing with my Science Fair project.

I am very interested in your experiments and will follow your blog with interest. What a great way to record your processes and findings.
Don't forget to publish your hypothesis before you conduct your experiments.
Congratulations.

I am also going to follow this blog with great interest. Congratulations on the innovative way you have gone about your Science Fair assignment. You have opened up a whole new range of possibilities and this is setting a very high standard for the e-portfolios we are wanting to expore. Geat work. I will keep watching.

This is a very interesting project, and I will follow it with interest. This blog is a great idea, and I will share it with my students in the US.
I am also interested in you science fair project. I will follow up on this project and get back to you. =)
