The Plymouth State College (PSC) Meteorology Program has developed this server to provide explanations of and access to detailed pictures of some basic cloud forms. The cloud images are relatively large (640x480) in order to show detailed structure and features. All of these pictures were taken in the local area around Plymouth, New Hampshire and most from the weather observation deck on the roof ... Full description.

Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. He obtained thousands of photomicrographs of individual ice crystals over the course of his lifetime. Images in this collection are scanned from glass lantern slides. Most snow crystals found in nature will fit into one of these seven main categories: ... Full description.

This site describes the fossils found in the fossil-rich calcareous nodules (Swedish: orsten) which occur in dark organic-rich shales known as alum shales in the upper Middle Cambrian and especially the Upper Cambrian of the Cambrian continent Baltica. These fossil-rich nodules were known for a long time as a source of excellent macrofossils, but they also provide a number of incredibly well-preserved ... Full description.

In this lesson students working in teams classify furniture, share their categories and rationales, then note how their different schemes vary arbitrarily. They then see how living organisms are classified, and note how these groupings are natural, nearly always reflecting the same ancestral relationships in nested hierarchies, regardless of the deeper criteria. Such patterns are revealed with a look ... Full description.

In this lesson, students will learn that some evolutionary change is rapid and discontinuous, and some change is gradual; how fossil evidence can provide clues to the past; and how speciation may account for evolutionary branching and diversification. Fossil shells of a land snail are arranged by layers of age into a sequence pattern suggesting gradual change, or punctuated equilibria. Students will ... Full description.

This site introduces a group of dinosaurs called ornithischians. There were many kinds of ornithischian dinosaurs dating back to the early Jurassic. The Ornithopoda included the hadrosaurs (duck-billed dinosaurs), the iguanodontids, the heterodontosaurs, the hypsilophodontids, and various others. The Ceratopsia included the horned dinosaurs, while the Ankylosauria and Stegosauria (now usually grouped ... Full description.

This information will provide students with an opportunity to understand the ideas proposed by Jean Baptiste de Lamarck in 1809. Lamarck was an eighteenth century naturalist who came to the idea that organisms change over time. Among other things, he proposed a mechanism for cumulative change that was dependent on the needs of organisms and resulted from the use or disuse of particular body parts. ... Full description.

In this activity, students will construct a set of sieves (four sizes) and use them to sort a soil sample. The activity will demonstrate that accuracy does not always have to involve expensive, high technology equipment. The sieves can be kept for use in later activities. A materials list and illustrated instructions are provided. Materials used to construct the sieves must be purchased. Full description.

In this activity, students will dissect a fish purchased from a fish market to study its external and internal anatomy. They will observe its gills, kidney, and blood through a microscope and take a variety of measurements of many of the internal organs. They will practice their observation skills by making accurate illustrations. These data and drawings will then be compared with some Antarctic fishes ... Full description.

Paleontologists occasionally find ancient tracks and footprints preserved in the rocks. This lesson opens the door to analysing those footprints, and gleaning information about body size and activities of the extinct animals that made the tracks. Students will learn that patterns can reveal much about the past, in light of the present; and that bipedalism has appeared several times. Relationships ... Full description.
