Liver Enzyme Lab
Purpose: In this lab, you will hypothesize about how environmental factors affect the
activity of an enzyme. You will focus on how enzymes function and what affects their
reaction rate and ability to work.
In our cells there
As the caffeine concentration rises, so does the mean heart

EVOLUTION OF BARBELLUS
Demonstrate one technique for hypothesizing about the evolutionary relationships among fossil organisms.
Demonstrate the use of the Law of Superposition.
Construct a phylogenetic tree based on fossil evidence.
Peppered Moth Simulation
The big idea: Changes occurred in the moth population due to pollution and predation.
This is an excellent example of how species can change over time!

The Snail is a gastropod, a soft-bodied type of mollusk that is basically a head with a flattened foot.
The soft body is protected by a hard shell, which the snail retreats into when alarmed. These
Homeostasis is the maintenance of a relatively stable internal environment. Just as your
pancreas regulates blood sugar by the release of insulin and glucagon, the kidneys
contribute to the maintenance of internal homeostasis by re
Interpreting Fossil Evidence
I. Purpose: How can fossils be used to relate the history of an era?
CA Standard: (8e) Students know how to analyze fossil evidence with regard to biological diversity,
episodic speciation, and mass extinction.
Our bodies are homes for many different kinds of microbes, including many different bacteria. The
microbes in your skin are divided into two general categories:
Resident microbes are permanent inhabitants of the skin of most pe
