This reference describes the relationship between reef formation and sea level, how it can be used to detect ancient changes in sea level, and how it might be used to predict the results of future increases in sea level. Topics include the coral environment, how reefs respond to changes in sea level, and how limestone forms. There is also an activity in which students use maps of present and past shorelines, bathymetry, and reef locations to predict where Florida’s reefs might form in the future.

This resource is a manual for instructing a laboratory exercise in plant reproductive biology. Students observe pollen tube growth in the presence of various chemicals, chosen such that the lab also provides a strong demonstration of the cellular flow of genetic information. This lab exercise is suitable for courses in plant biology and reproductive biology, and the focus can easily adapted to make it suitable for cellular and molecular biology courses.
This article from the Australian Telescope National Facility describes the death of massive stars. It discusses the formation and characteristics of supernovae, hypernovae, neutron stars/pulsars, and black holes. The article includes an animated diagram showing how the pulsar beam is observed from Earth.
This brief summary provides an overview of the creation, abandonment, and reclamation of stone walls in New England.
