By matching photos of gray whales with photos from a gray whale identification catalogue, students identify whales. Hear-Sighted Students investigate their own sense of location through experimentation and simulation. Echolocation Slinky wave puzzles are used to determine the distance between a student and an object. Sound Travels Students build an echolocation model to determine distance to an object. Researching Gray Whales - March 21 Original research data in text and graphic forms is analyzed by students as they examine how gray whale research is conducted.
Students collect, observe and draw sediment animals from a nearby freshwater or saltwater wetland.
This role playing game helps your students understand the food chain concept. Observing Living Plankton - June 20 Concrete experience with living plankton is used to stimulate student questions and further study. In Search of the Wild Plankton Students construct a plankton net and collect live plankton for later observation. Magnifying the Problem Construction of a water lens microscope allows students to observe the live plankton they have collected with their plankton nets. After an examination of critical factors which contribute to the abundance of plankton, students perform a simple experiment showing the influence of density on upwelling.
