The NGS is a telecommunications based science curriculum that allows students to collaborate as research scientists by conducting original research and finding their own answers. Using a computer, they record and graph data, display software generated maps, and send information electronically.
Students begin the unit by examining a sample of classroom trash.
After considering various definitions of trash, students compose their own definitions and start an investigation to find out how much trash is produced in their schools and communities and where their trash goes after the garbage trucks take it away. Throughout the unit, students keep research journals in which they record hypotheses, observations, and other data. In subsequent activities, students use telecommunication to collaborate with their teammates about trash production and trash disposal methods, take an in depth look at incinerators and landfills, and analyze waste reduction strategies. The teacher's guide contains lesson objectives, teaching tips, background information, estimated preparation times, lists of materials needed, homework suggestions, and extension activities for the students. Three wall maps and sample library catalog cards are also provided.
