Science This Week!

This past week in Science, some science ideas I learned were how diseases can spread and be tracked, what it means for something to be alive, and characteristics of viruses and bacteria and other things.

We learned how diseases can be spread by giving each person in our class a vile of liquid that was either contaminated or non-contaminated. We then swapped liquids with classmates, causing most healthy people to become infected by someone else that's infected. To track where the disease began, we made a web of who we each switched with, then who those people switched with. By doing this we were able to narrow down the original diseased person to two people, which in my opinion is pretty good.

We learned about Viruses and Bacteria by coming up with and sharing what we believe are their characteristics.

It is so important to know how to track disease because in order to properly vaccinate/control disease outbreaks so that the disease can be put an end to. For example, if there are outbreaks of a disease going on around the world, doctors monitor where they are occurring, then send people to that location to vaccinate and control the disease spreading there. I believe that without disease tracking there would be a lot more people becoming ill of or dying from illnesses.

Thanks for reading!
