I searched for hours in the spring for a good explanation of CRISPR that was at a level my students could understand. Finally, a video!

Two weeks until the start of school. This year, I'm moving to more digital resources, so my first-day questionnaire asks students about their access to computers and smart phones. 
A short survey for students to fill out on the first day to help the teacher get to know them.

I am so glad that Seaworld is going to stop the practice of captive whale breeding. Whale evolution is driven by culture and learning within their specialized groups...family groups. Why did we ever think it was a good idea to remove these animals from their natural environments? 
Genomes of 50 whales from different social niches reveal that their varying cultures are also genetically distinct

Beautiful.Im amazed by all the wildlife that one day may not be around us.And thats why I want to be a biologist when I grow up.

One of my favorite early demonstrations is this one on "sewer lice." Basically, you submerge raisins in carbonated water (or white soda) and they will float to the surface and then sink and repeat this all day long. I ask my students to make a guess about whether they think the creatures are alive. Sometimes I even add a backstory about the creatures being discovered in the sewer and that they are edible. You can eat one to really mess with the freshman!

+Nina Nuesslein I would have student groups generate a set of observations and come up with a hypothesis as to whether the 'sewer lice' were alive. We then discussed the difference between an observation and an assumption. Next, I would have them cross out items on their list that were not observations. Finally I would ask them what other observations they would need to make in order to form a working hypothesis as to whether the 'sewer lice' were organisms.This event can then lead into scientific method and the characteristics of life.

During the evolution unit of AP Bio, we do a case study on lice, which examines how three different species of lice (head, pubic, and body) evolved. It's a great case for the "gross" factor and an excellent way to show how phylogenetic studies reveal relationships. This article from Forbes about resistant lice will be a great follow-up to the case:

Do you have a handout of some sort to accompany this activity? I would love to share this with my students! Thank you!

I've been re-working my AP ecology unit to accommodate "senioritis." The changes move the unit away from lectures and note-take to case studies and investigations. The first adjustment was to the Rolly-polly (pillbug) investigation. I've adjusted this lab to include 2 pages of case-work on animal behavior which includes topics such as innate, learned, taxis, and evolutionary basis of behavior. The final task is for them to design and conduct a behavior experiment with pillbugs or other classroom specimens.

+Kevin Murray , I love that site.  I use a lot of their case studies.   I haven't paid the fee for the answer keys,  if I can't figure out the answers then the content is probably too difficult for my students.

Every year I try to do an "article of the week" where students read something current and summarize. With all the required AP labs, this usually ends up being "article of the every other week." 
Students read scientific articles or journals and write a summary using this framing guide. Essays ensure students have read and understood the content.

This investigation models osmosis using dialysis tubes that contain different concentrations of sucrose; the tubes will gain water dependent upon the molarity of solution they are placed in

This buoy takes data from the Mississippi about temperature, pH, nitrate levels..etc. I would love to do some projects next year where students look at real data like those collected from the river. Buoy data can found at http://buoybay.noaa.gov/

I've been getting a lot of requests to share documents I store on google drive.  Anyone can edit these documents without me giving permissions.  Just click on the "file" tab and either download it as a powerpoint or "make a copy" which will copy it to your own drive.    I don't give edit permissions because if a person made a change, it would also change my documents.  I recognize that everyone has different styles, different classes, and different age groups, so editing and changing the files is perfectly fine.   Also, it's nice when readers alert me to typos and errata!

Example:  This screenshot is from a doc file that I don't own.  If I wanted to use it, I could make my own copy and then make any changes I wanted.    My changes would not effect the owners' original copy.

How do we access the google doc?
Thank you

I don't teach chemistry, but I think I could have fun with this game.

To align lessons with Next Generation Science Standards, I've been working on activities for 9th graders involving cellular respiration and photosynthesis. It's been challenging to present the material in a way that those students can understand. They haven't taken chemistry and have no concept of redox reactions and electron acceptors.

I started with the question "Why do we need oxygen?" What followed was a mini-case study on the Chicago Tylenol murders, cyanide, and finally the electron transport chain. It is intended for 9th graders, so the model is really simplified.

Resources for students and teachers of biology and the life sciences.
Introduction
The Biology Corner is a website I started in 2000, over the years I have added content and resources I have used in my biology classes.  Teachers and students alike can find help with concepts, images, and practice quizzes for all major biological topics.  I also include photos of anatomy, mainly from classroom dissections and human models I have in the classroom.
