Evolution Projects

Check out some of the amazing work our Honors Biology students created to share with some local middle school students to help them learn the basics of Evolution:

 

Some of the students created twitter accounts for middle schoolers to follow and included key concepts as well as #hashtagvocab

Unit 10: Gas Laws Overview

Today we’re going to begin studying Gas Laws… (and that doesn’t mean the rules on Dutch Oven or letting one go in a crowded elevator).

We’re going to try some new classroom techniques for this final unit and create an “Open” classroom. Below are the expectations of you the student and of me the teacher.

Student Values:
