Class Info:
Biology is a class where we will have fun learning about how life works! We use a variety of science and engineering practices to help us make connections and understand disciplinary core ideas to the Biology field. Our class is standards-based and student-led. I really try to focus on student learning for all and meet the students where they are on the life science journey. Some of the topics we will cover are natural selection, population dynamics, energy and matter in systems, protein synthesis, photosynthesis, and cellular respiration. Please join my Remind by following the link to the side to stay up to date on everything in class. 
A Little Info about Me
My name is Leiha Chaisson. I will be your science teacher for the year, and would love to share a little information with you. I am a Mustang Bronco through and through. I graduated from MHS in 2002. My husband and I have a 13 year-old son at Central Middle and a 7 year-old daughter at Mustang Trails. We have two dogs and a bearded dragon. I have always enjoyed learning about the world around us and questioning how things work.
We will be covering a ton of exciting things this year! You will find out that I love rules, but I also love to have fun! I will try to make sure to encompass everyone's learning style. We will do some reading, some writing, some drawing, and a ton of hands-on activities!
I look forward to working together!
