Fall 2019 Biology

September 23, 2019

     In Ms. Allnutt’s biology classes, students have been learning what the word “biology” means and what it means to be considered alive. If they learn nothing else this year, they will at least remember what “bio” means! 

     Students in general biology have spent lots of time working on their scientific thinking skills through labs based on observation and questioning. We learned about a girl named Addie who got extremely sick over and over again. We have been using this case to learn about bacteria, antibiotics, and the development of antibiotic resistance through evolution by natural selection. We have discovered where around the school bacteria can be found, have used mathematical models to predict how bacterial populations grow through reproduction, and learned how they interact with different types of antibiotics.  Below are 2 examples of the bacteria students collected and grew in Petri dishes.

     In the co-taught classes, students have learned about the different molecules essential for life, such as proteins and carbohydrates, and about what makes water such a unique compound and important for life on Earth. We are currently learning about the structure of cells. There is a lot of new information in this chapter, but there are also several fun projects and labs. We will be doing a project to make a model of the cell to help remember all the parts and their functions. The model can be edible (cakes or jello or pizzas, oh my!) or it could be made out of clay or Legos! Every year students have fun with this project so I am excited to see how creative we can get.
