Skulls : structure and function
Skulls have been designed for both form and function. Through the use of text and labeled photographs, this website explains how specific skull adaptations meet the needs of organisms. For instance, visitors will discover that some beaks of macaws are attached to their skull only through ligaments to limit the amount of force put on the skull when the birds crack open nuts. The site also presents a series of skull facts, questions, and answers provided by scientists. A unique feature allows visi

Observe a lunar eclipse
This Earth science animation enables middle and high school students to observe the events of a lunar eclipse. The introduction explains why the moon's appearance changes as is moves through the Earth's shadow. The animation shows the moon darken as it enters the penumbra, turn reddish-orange as it reaches the umbra, and lighten as it leaves the other side of the penumbra. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze

Observe the origins of some ocean floor sediments
This Earth science resource illustrates the sources of ocean sedimentation along coasts, on the ocean floor, and at hydrothermal vents. Students click on these ocean locations to see examples of the formation of hydrogenous, biogenous, and terrigenous sediments. For each sediment type, the resource provides two enlargeable images. When enlarged, each image is accompanied by descriptive text. For example, the hydrogenous sediments are represented by a close-up view of ferromanganese nodules, as w

1.5 Clades and mammals
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.

Where are the Plastics Near Me? (Mapping the Data)
Data collected in the Where are the Plastics Near Me (Field Trip) activity are organized by student groups in a fairly student-led and independent fashion to create a useful and informative Google Earth map. The students will create a map, use that map to analyze the results, adjust the map to include the results of the analysis, and then write a brief summary of their findings. Questions of fate-and-transport of plastics are primarily what are explored. If data was gathered in the field trip bu
