Native Plant Garden

native plant gardenAssessing Biodiversity Using a School Garden

by Jenn Yost, Carla Fresquez and Bill Callahan

One way that we can protect biodiversity is by restoring degraded habitats to more natural conditions. This process can be simulated at a school through the restoration of a degraded plot of land into local native plant communities. Planting a native garden is a way to expose students to local biodiversity, teach them the importance of biodiversity, and mimic what can be done on a large scale to restore ecosystems once they are degraded.

Students 1) develop their own methods to quantify biodiversity, 2) measure biodiversity in a native garden, and 3) gain first hand experience in native plant gardens, restoration, and human impacts on environments.

What’s Stomata With You?

what's stomata with youUsing Leaf Epidermal Peels to Determine Stomatal Density

by Catherine Wade and William Callahan

This module provides an opportunity for students to observe leaf stomata and make predictions about interactions between plants and environmental conditions. After introducing students to the basic form and function of stomata and discussing photosynthesis and transpiration, students will hypothesize about the distribution of stomata on the upper and lower leaf surfaces. Then, they make wet mount slides of leaf epidermal peels to view stomata under a microscope and calculate average stomatal densities for the top and bottom of the leaf.

Fellow Catherine Wade produced this video to explain the concepts behind leaf stomata and their importance in regulating water loss in plants.

A Matter of Human Proportions

a matter of human proportionsAre You Vitruvian?

by Vikram Baliga and Sarah Baumgart

This module is an opportunity for students to learn: 1) How to use the metric system to measure linear distances; 2) Whether proportions that exist between parts of the human body are consistent across individuals; and 3) How to form a hypothesis, analyze data, and argue whether evidence supports the hypothesis.

Hold Your Breath!

hold your breathby Vikram Baliga and Sarah Baumgart

This module helps students learn about the mammalian dive response. Students simulate a dive by submerging their faces in cold water for 30 seconds. They measure heart rate and body temperature before and after the “dive”. Students learn how the human body responds to stress (cold water) and they convey their findings using bar graphs and a final lab report.




Fellow Vikram Baliga produced this video to accompany his Dive Response module for inquiry-based education in high school science lab.

Spit Lab

spit labMacromolecules and Environmental Effects on Enzymes

by Jenn Yost and Erin Mejía

In this module students will do an activity and a lab. A cut-out activity illustrates the anabolic and catabolic functions of enzymes, enzyme specificity, and the individual components of macromolecules. Students then test the effects of temperature on enzymatic activity in spit.

Ethical Guidelines for the Use of DNA Technology

by Tara Cornelisse

In four 2-hour class sessions, AP Biology students receive enriched, in-depth Power Point lectures that accompany their study of Campbell’s AP Biology textbook to explain the mechanics of DNA modification, and engage in two different group activities to apply their understandings of both science and social issues through engaged ethical reasoning, debate, and presentations.
