In this activity, students will design experiments to gain some understanding of the feeding rates of Rotifers and/or Tardigrades (charismatic microfauna). These organisms are the largest found in Lake Hoare in the Taylor Valley, making them the top predator in the food chain of this lake ecosystem. The rate of feeding and the amount of food available may determine population size. Students will use ... Full description.

The Ramsar Wetlands Data Gateway is a database containing information on protected international wetlands. In this activity, users search the database to find a wetland that they are interested in helping to protect. Using the database search capabilities, users select various wetland characteristics and generate a report on the sites that meet their search criteria. Then, they access an interactive ...
