Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Cluster of questions on acid rain deposition.

This short video is an excerpt from the longer video Acid Test: The Global Challenge of Ocean Acidification, produced by the National Resources Defense Council (NRDC). This short version summarizes the science of ocean acidification as well as the social implications.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.

Students research the acidification of freshwater streams and lakes, identify at least one of the sources, and determine how their daily activities contribute to the problem.

Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

Acoustics (from Greek ακουστικός pronounced akoustikos meaning "of or for hearing, ready to hear") is the science that studies sound, in particular its production, transmission, and effects. The science of acoustics has many applications which are dependent upon the nature of the sound that is to be produced, transmitted or controlled.

Using the article "Stop Raising Awareness Already" by Cristiano and Neimand and a six-step template, students create a plan to show how they apply the knowledge learned throughout the term to make a broader impact. The students are asked to very narrowly choose a single action they want a group of stakeholders to take and develop a multiple-step plan to accomplish the action. The students are required to select and justify a targeted stakeholder, develop an action, identify a messenger that can influence their targeted stakeholder to take the action, develop a sticky message relating the "ask" to the goal of the campaign, and document their key assumptions imbedded in their action plan.

Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.

Action research is a common journey for graduate students in education and other human science fields. This book attempts to meet the needs of graduate students, in-service teachers, and any other educators interested in action research and/or self-study. The chapters of this book draw on our collective experiences as educators in a variety of educational contexts, and our roles guiding educator/researchers in various settings. All of our experiences have enabled us to question and refine our own understanding of action research as a process and means for pedagogical improvement.

This assignment is a 10-hour, out-of-class project where each student
designs and carries out an action plan to enhance sustainability.
Students select from a large suite of alternative actions, most of which
can be quantified for reductions in CO2 and energy consumption, as well
as in dollar savings.

A workshop and facilitation guide to support B.C. post-secondary institutions to prevent and respond to sexual violence and misconduct. Active Bystander Intervention is a 90-minute workshop for all members of the campus community: students, faculty, administrators, and staff. This training helps learners acquire the knowledge and skills needed to recognize and intervene in an incident of sexual violence as well as discuss strategies for creating a safer campus community. Uses the 4D’s (Direct, Distract, Delegate, Delay) Active Bystander Intervention Model. (The slide deck that accompanies this resource can be downloaded from the Introduction.)

Inside, you’ll find many ideas you can use to enliven your synchronous online class meetings with active learning activities.

By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional and learning opportunities associated with active tectonic examination of large population centers.

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell membrane. Concentration gradient, sizes, shapes and polarity of molecules determine the method of movement through cell membranes. This activity is associated with the Test your Mettle phase of the legacy cycle.
