This applet explores Mendel's ideas about dominant and recessive traits. The student chooses the leaf and stem colors of the parent plants before pollination, and the applet displays the resulting plants of the next generation. The student then chooses from this second generation the parents of the third generation, the offspring are displayed, and so on. The experiment can also be conducted using ... Full description.

Containing a highly interactive computer activity for students, this module examines evidence from the fossil record, behavior, biomechanics and cladistic analysis to interpret the sequence of events that led to flight in the dinosaur lineage. The module concentrates on the process of science - how we know what we know. It also contains background information, lesson plans, handouts, and assessments. ... Full description.

This activity will allow students to observe and interpret fossil footprint evidence. From the evidence, they are asked to construct defensible hypotheses or explanations for events that took place in the geological past. Students will be asked to propose explanations and make predictions based on evidence, recognize and analyze alternative explanations and predictions, understand that scientific ... Full description.

At this site, students learn that sound moves five times faster in water than in air and cleaner fish have cleaning stations where they remove parasites. Students deepen their knowledge with this ocean life challenge. They learn about how living in the water differs from living on land. An ichthyologist first explains that ocean creatures have special features that allow them to breathe, eat, communicate, ... Full description.

This activity will help students learn about how tree rings provide a record of past growing conditions and, by inference, climate. They use this principle to work out how cores from three different trees (three strips of paper marked with stripes to represent rings) fit together to represent a longer period of time and then use this composite record to plot a graph of changing climate conditions. ...

In these activities students will discover the characteristics that enable Antarctica's many life forms to live in this continent of extreme cold, wind, and extended periods of light and darkness. In this weeklong unit, students research how flora and fauna have adapted to thrive in Antarctica, and use their knowledge to create imaginary polar organisms. Throughout this module, students collect their ... Full description.

This site presents the results of underwater photography team dives out of the US Antarctic Program's base at McMurdo Station, on Ross Island in Antarctica. For three visits in late austral spring, photos were taken on scuba dives and field excursions at locations around McMurdo Sound: Ross Island and the Antarctic mainland. The team was led by a professional underwater photographer/cinematographer. ... Full description.

This report describes how paleontologists infer what dinosaurs looked like and how they behaved using evidence from fossil bones and, sometimes, comparisons with modern animals like the elephant. By comparing the size of the front and rear leg bones and the feet of an elephant as well as the dinosaur, one researcher was able to conclude that the sauropod Jobaria could "stand up", supporting its weight ...

This lesson introduces students to the broad concept of invasive species. Students prepare a written case study on an invasive aquatic species, followed by an oral presentation. They will define, compare, and contrast invasive species, alien species, and native species, describe at least three problems that may be associated with invasive species, and describe at least three invasive species, explain ...

In this lesson students discover how ocean waves form and the effect of extreme storms on wave formation. They will investigate the "Portland Gale" of 1898, the Halloween Nor'easter of 1991 (known as "The Perfect Storm"), and discuss hybrid storms and tsunamis. This hands-on activity uses on-line data resources and includes: focus questions, learning objectives, teaching time, audio/visual materials ... Full description.
