BIOL 1215: Biology Laboratory II

In this five-day lab course, students perform experiments that illustrate the principles learned in BIOL 1213.

Learning outcomes

  • Define the various terminology associated with mitosis and meiosis and explain and draw the various stages of each process.
  • Understand how variation in organisms is created through the process of meiosis and fertilization.
  • Formulate and test hypothesis concerning the Galapagos finches to determine if the process of character displacement has played a role in their evolution.
  • Draw tables and graphs correctly to show data and explain and interpret the results.
  • Understand and explain the terminology associated with cladistics and then use cladistics analysis to correctly predict phylogenetic relationships among organisms.
  • Use various pieces of equipment to collect abiotic and biotic samples from freshwater aquatic ecosystems, and also analyze the samples in the lab, and then use this data to determine the 'health' of the ecosystem.
  • Write a scientific report correctly using the IMRD format, and use and cite academic information sources correctly.
  • Investigate the body plan and natural history of an invertebrate animal species, and then design and implement experiments to test the animal's response to various stimuli.
  • Collect, analyze and interpret behavioural data, and present the information both as a written report and as a verbal presentation.
  • Know the body plans of animals in the major phyla as well as their defining characteristics and also the major evolutionary advances in the phylogeny of animals.

Required text and materials

Students will be required to print their own laboratory manual prior to their first day in class. Other supplies will be provided during the lab. For safety reasons, students must wear closed shoes. No open-toed shoes or sandals are permitted in the labs.

Assessments

Students will receive a final mark out of 100. This mark is determined on the basis of lab assignments, quizzes, and reports; as well, you are assess on your attendance and participation.

Students cannot miss more than two lab sessions or an incomplete grade will be assigned.

For safety orientation reasons, students are required to attend the first lab session.
