What’s that Sound?

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.

Land to Sea

land to seaSearching for the Source of Pollutants

by Max Tarjan and Will Federman

In this module students work in small groups with map-based data to learn about watersheds and to find a likely source of pollutants. After a short introduction, students work together to intrepret ther maps provided and to support an argument, stating where the pollutant is coming from, using the map data as evidence. The module provides all the supporting materials needed to run a 90 minute activity.

In this module, students learn: 1) How substances and organisms on land can affect ocean life, 2) How human activities may disrupt ecosystem integrity, to identify the watershed that supplies a river, 3) How to interpret maps of watersheds and land use, and 4) How to combine information from different maps using map scales, and 5) How to make estimates based on map data, and engage in argument from evidence.
