Factors Affecting Friction
Based on what they have already learned about friction, students formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter? and Does Area Matter?), students design and conduct simple experiments to test their hypotheses, using procedures similar to those used in the previous lesson (Discovering Friction). An analysis of their data will reveal the importance of weight to normal friction (
How Tall Are We?
Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height

9 Sedimentation at the end of the Caledonian Orgeny; Section 10 Legacy
Some of Britain’s most dramatic scenery is to be found in the Scottish Highlands. The sight of mighty Ben Nevis, the desolate plateau of the Cairngorms, or the imposing landscapes of Glen Coe can unleash the call of the wild in all of us. Although these landforms were largely carved by glacial activity that ended some 10,000 years ago, the rocks themselves tell of a much older history. The Highlands are merely eroded stumps of a much higher range of ancient mountains. This unit is an account o

Effective Methods of Training Biology Laboratory Teaching Assistants II: Preparing TAs To Be Effecti
One of the most important factors in the success of undergraduate biology laboratories rests with the instructors, often undergraduate or graduate students, who teach them. This ABLE 2000 workshop, which continued a session presented at ABLE 1999, focused on the theme "teaching effectively in the laboratory." Topics included preparation, organization, supervision of group work, and involvement of students in discussion. In addition to presentations by the workshop organizers, participants engage

Scientists throughout the world are increasingly interested in the relationship between science and society. Part of their concern is with the social responsibilities scientists have in relation to broader public interests. That raises important issues to do with the ethical and social dimension of scientists' work and how scientists explain – and perhaps justify – their work to the wider public.
