How to Keep Your Online Notebook

Here is a screencast showing you how to create your online lab notebook for AP Biology:

Establishing DNA as the Genetic Material

Once upon a time, we didn't know that DNA is the genetic material.  There were some really cool experiments that people did to figure out what was going on.  I have summarized them in this screencast:

Here is a good video on the history of the discovery of the structure of DNA:

 

Here is a good video on the process of replication:

 

Graphing data over time and finding rates of reactions

In our Photosynthesis and Enzymes labs, we looked at change in transmittance or absorbance over time to measure the progress of a reaction.  This screencast will tell you what to do with your data.

Breathing and Gas Exchange.

Below are parts 1 and 2 of a screencast I did on Breathing and Gas Exchange
