This week in science we learned more about what's inside our petri dishes, cell and virus structures, and microscopes.
We learned about our petri dish contents by studying them and looking at the amount of colonies (when bacteria reproduces into lots of bacteria) each dish had. We then discusses the characteristics of the colonies.
We learned about cell and virus structures by researching them and drawing labeled pictures of a cell and virus. This helped me understand them A LOT more because it showed me what they really look like and the different features and charicteristics each has. For example, without having to personally research and draw a bacteria cell, I would not have learned what a Ribosome or, converter of food to energy is.
To learn about microscopes, my group and I took a look at one. Also, I attended a mini-lesson from Mr. Sagen on dry/wet mount slides which I learned a lot from. One thing I learned in the ini lesson is that pipettes are used to apply liquid on a wet mount slide.
It is important to know about what is inside of our petri dishes because I believe it is silly to perform an experiment such as ours without understanding it. Next, it is important to learn about virus and cell structures because #1 They are all around us and #2 They largely affect our petri dish experiment. Finally, it is important to know about the proper use of a microscope and slides because they are great, useful tools and they are something you use your entire science career to view important things in.
