- Abstract:
This Public Broadcasting Service (PBS) activity explores the controversy over whether or not there is life on Mars. Part of the Mysteries of Deep Space Program that originally aired in April 1997, the activity includes instructional objectives, background information, and discussion/essay questions related to life on Mars. It also features an activity where students can grow microorganisms, examine them under a microscope, and analyze their observations with the aid of follow-up questions.

- Abstract:
This hands-on activity gives students the opportunity to use skills and concepts developed in a unit on cells with an unknown organism. They are asked to design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum. The activity includes background information, preparation time, abstract, materials, procedure, evaluation, and additional thoughts. The activity is part of The Access Excellence Fellows Collection, an archive of the favorite classroom activities submitted by high school biology and life sciences teachers participating in the Access Excellence program.

- Abstract:
This on-line exercise is focused on lactic acid bacteria, a group of related bacteria that produce lactic acid as a result of carbohydrate fermentation. It includes a protocol for the enrichment of lactic acid bacteria from enriched samples (like yogurt, sauerkraut, decaying plant matter, and tooth plaque). Three parameters are measured: growth, culture diversity, and pH. The exercise also includes instructions for the isolation of some of these bacteria by using the streak-plate method.

- Abstract:
This online lesson plan was designed for students taking part in the active research project to document the distribution of a new species of tardigrade, a microscopic invertebrate animal. The project is part of a nationwide online collaborative research project. The lesson plan offers instructional procedures for teachers and lists materials and procedures for collecting, observing, and culturing tardigrades. The lesson involves collecting samples in the field, examining and classifying tartigrades in the samples using a microscope and an online taxonomic key, and keeping a biological journal of their study. Links are provided to other components of the species distribution project.
