Who Was Charles Darwin?
In this lesson, students will learn firsthand, by reading his journal entries and letters, how Darwin arrived at his theory. They also will gain a better sense of Darwin's journey and the role it played in his scientific career. In the first activity, Darwin's Great Voyage of Discovery, students will read his account of his voyage on the Beagle and see how this experience inspired him to devote the rest of his life to developing and refining the theory of natural selection. The second activity,
This site provides information on plate boundaries, which are found at the edge of the lithospheric plates and are of three types: convergent, divergent and conservative. Wide zones of deformation are usually characteristic of plate boundaries because of the interaction between two plates. The three boundaries are characterized by their distinct motions which are described in the text and depicted with block diagram illustrations, all of which are animated. There are also two maps that show the
Interactive atmosphere lab
The ozone layer makes up an important part of our atmosphere. This informational activity, part of an interactive laboratory series for grades 8-12, explores changes in ozone concentration with altitude. Students view a diagram that shows the layers of the atmosphere with a temperature scale running from the surface of the Earth to the outermost reaches of the atmosphere. After reading introductory material, students are presented with nine questions about the layers of the atmosphere and intera

2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
Compare Human-made Objects with Natural Objects
In small groups, students will experiment and observe the similarities and differences between human-made objects and nature. The students will compare the function and structure of hollow bones with drinking straws, bird beaks, tool pliers, bat wings and airplane wings. A classroom discussion can be held to discuss similarities and differences that were observed along with follow up assessment activities such as journal writing and Venn diagrams.
4.6 New Lanark and the Falls of Clyde
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
