argument from evidenceAssessing Argumentation Using the Topic of Fracking

by Jeff Jenkins, Chrissy MacLean and Dawn Krenz

Students living in rural communities impacted by ongoing and proposed extractive mineral development (fossil fuels and mining) will gain a greater appreciation and understanding for how different segments of society (government, corporate, and community) produce information to serve their own interests and how ‘factual’ information is often contested between these groups.

Students learn: 1) How to summarize the key points of an argument, 2) How to question the validity and subjectivity of information, and 3) How to summarize and convey a broad set of information in a succinct fashion.

what's that soundQuantifying and Describing Marine Mammal Sounds

by Caleb Bryce, Kimberly Goetz and Burnee Yew

Marine mammals use sound for feeding, communication, predator avoidance, and navigation. Students are introduced to the properties of sound by quantifying and describing sounds from several types of marine mammals (toothed whales, baleen whales, sea lions, and true seals). Students examine differences in sounds between marine mammal species and then use that knowledge to predict the source of a mystery sound.

Students learn: 1) Basic properties of sound, 2) How to interpret spectograms and waveforms, 3) Why marine mammals use sound, and 4) How to describe the diversity of sounds made by marine mammals.
