(You may want to see that all the listed animals are selected by one or more students.) The Web site cited previously will prove helpful in their research.
After they have completed their research, have students build models of their chosen animals, based on what they have learned.
Yet some organisms, although smaller and not as strong, escaped this predator.
Why do you think some organisms survived attacks while others didn't?
Present students with a shortened version of the list of animals, limiting the list to those described on the Web site mentioned in Procedures.
Instead of having students do research on their own, download these descriptions for them.
Definition: A longitudinal, flexible rod of cells that, in the lowest chordates and in the embryos of the higher vertebrates, forms the supporting axis of the body.Following research and discussion, students should choose one geologic dating technique and create a visual display detailing the procedure. Learning from the Fossil Record Presented by the University of California Museum of Paleontology.On their display, students should include steps in the procedure for dating fossils. Contains lesson plans, activities, and essays for studying about dinosaurs and fossils in grades K-12.Many of them appear to be early ancestors of higher forms of life, while others appear unrelated to any forms on record since.
Allow time for students to use the materials you have provided or the Internet to find out more about the Burgess Shale.Explain that the Burgess Shale is an area in the western Canadian Rocky Mountains discovered in 1909 by Charles D.
