Collect your notebooks from the lab area and answer the following questions in your notebook:

• What is today’s date?

• Today, later in the period, we will be conducting t-tests on the leaf pack data we collected in class and graphing the results. Are you able to do this? Are you confident enough in your abilities to show someone else?

• What energy can be found in ecosystems. How does that energy move through the organisms that live in the ecosystem?
