New York student Shadia Wood tells how she became an environmental activist in this video adapted from Earth Island Institute’s New Leaders Initiative. Wood lives near several toxic waste sites and was concerned to learn that the New York Superfund—the money set aside for cleaning such sites in her state—had gone bankrupt. Working with other students and environmental groups, Wood lobbied the New York legislature for eight years until the Superfund program was refinanced. Environmentalist Laura Haight says that this law was the most important environmental law passed in New York State in a decade.

In this video segment from Teaching Middle School Life Science, master teacher and science education specialist Sally Crissman asks a small group of middle school students what they already know about pond life before starting a new investigation. Crissman emphasizes that assessing prior knowledge is an important part of the learning process. To do this, she asks students questions to gauge their understanding and experience with a subject, and may also have them make predictions about what they might observe. Crissman also talks about the effectiveness of regularly reviewing what students have learned with them before pushing their learning further.
