Evolution and the Nature of Science Institutes: Lesson Plans
Conditions of Use:
Read the Fine Print
Rating

This website provides access to lesson plans published by the Evolution and the Nature of Science Institutes (ENSI). Based on 32 key ideas of scientific thought, the ENSI program emphasizes the importance of teaching the nature of modern science before introducing the elements of evolution as an example of modern scientific thinking. This website features lessons in three categories - the nature of science, the origins of life, and evolution. Lesson plans are organized into eight sections including an overview of concepts and objectives, logistics such as time, materials, and teaching preparations, and ready-to-use handouts and worksheets for students. These lessons are intended for use in any high school biology course, and may also be used in middle school and/or lower division university courses depending on slight modifications and the experience and level of students.

External Symmetry of Crystals, 32 Crystal Classes
Conditions of Use:
Read the Fine Print
Rating

This site is a lecture by Dr. Stephen Nelson from Tulane University that explores the 32 possible combinations of symmetry operations that define the external symmetry of crystals. The lecture defines the six crystal systems (triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric) and explains the derivation of the Hermann-Mauguin symbols (also called the international symbols) used to describe the crystal classes from the symmetry content. Tables and illustrations accompany the text.

Rating

This virtual five-day field mapping project allows students to construct a geological map from data provided by the web site. Students collect geologic, structural, paleontologic, strain and microstructural data observed at specific localities. Students are then able to derive a structural history for the area, including a field map, stereographs, and deformation plots. The site contains photographs and images, data, and all information that is needed to complete the exercise. It also provides solutions to some of the exercises.
