1D Uniformly Accelerated Motion
Rating

The representation depicts an object moving along a "track" marked in .5 meter intervals. As the object moves, displacement-time, velocity-time, and acceleration-time graphs record the motion in real time. The user may select various types of motion to be depicted, as well as edit a velocity-time graph and have the resulting motion depicted. As the object moves, color coded vectors display its displacement, velocity and acceleration.

Acacia Tree Ants
Rating

The phenomenon is the symbiotic relationship between the acacia ant and the swollen thorn acacia tree, shown in a 2:18 minute video. The ant provides protection for the tree against preying insects and other plants competing for sunlight, and the tree provides nourishment and shelter for the ant and the ants' larvae.

Animation of Himalayas Forming
Rating

The representation depicts two plates colliding, specifically the Indian Plate and the Eurasian Plate. The oceanic crust on the leading edge of the Indian Plate is shown to move beneath the continental crust of the Eurasian Plate, causing the ocean between the continental plate material on the two plates to gradually become narrower. As the Indian Plate pushes beneath the Eurasian Plate, the continental plate material on the edge of the Eurasian Plate buckles and folds. When all of the oceanic plate material on the edge of the Indian Plate has moved beneath the Eurasian Plate, the continental plate material of both plates collides, causing the edges of both plates to fold, resulting in the formation of the Himalayan Mountains. This representation utilizes two simulated views of the mountain formation and six satellite images of the Himalayas. Each satellite image zooms out a little further until finally it shows most of the country of India and the Tibetan Plateau with the Himalayan Mountains in between. The animation can be advanced one frame at a time or viewed in its entirety.

Astronomy Picture of the Day - Lunation
Rating

The phenomenon is a series of photos of the moon taken daily during one lunar cycle. The photos show the various phases of the moon as seen from Earth and show that the moon has a slight wobble during its elliptical orbit. The photos also show the slight change in appearance of the moon's size during its orbit and show that the same side of the moon is always seen from Earth.

Biology Graphs - Predator and Prey
Rating

The phenomenon is the numerical relationship between the population growth of predator (lynx) and prey (hare) over a 90 year period as shown in a graph. The graph shows that as the population of hares increases, the population of lynx increases. As the population of lynx continue to increase, the population of hares decreases. Questions probe student thinking on this relationship and other factors that may impact the population of the hare and the lynx.
