What is poetry?
Have you always wanted to try to write poetry but never quite managed to start? This unit is designed to illustrate the techniques behind both the traditional forms of poetry and free verse. You will learn how you can use your own experiences to develop ideas and how to harness your imagination.
Studying the arts and humanities
This unit is an introduction to studying the arts and humanities. It takes you through a series of exercises designed to develop your approach to study and learning at a distance and improve your confidence as an independent learner.
Start writing fiction
Have you always wanted to write, but never quite had the courage to start? This unit will give you an insight into how authors create their characters and the settings for their work. You will also be able to look at the different genres for fiction.
One reason why caecilians are considered to be amphibians is because they go through metamorphosis to reach adulthood. Caecilians are unique amphibians because some of them lay eggs, but some of them give birth to live young.
Butterfly pupa anatomy
The pupa is the third stage of the butterfly's life cycle. The caterpillar creates a pupa, sometimes called a chrysalis, and emerges as the adult butterfly after metamorphosis. The butterfly's wings will be used for flying.
Buffalo grazing on Wyoming prairies
Grasslands are found where rainfall is low and temperatures are extreme. Grasslands experience drought and occasional fires. The soil of grasslands is deep, moist, and nutrient rich from dead grass and other organisms, which is good for agriculture.
Blood flow of moving Lumbriculus
Observe blood flow and muscle contractions in each body segment of Lumbriculus variegates (note how blood flows in relation to the worm turning in the capillary tube).
Bee on flower
Bees visit flowering plants to collect nectar so they can store it as honey back at their hives. As a bee visits one flower after another, pollen collects on its entire body and especially on the legs. Bees help pollinate flowers while they collect nectar. This is a mutualistic behavior.
Balance and flux
Ecosystems and populations of organisms within ecosystems function by the principle of balance and flux. Balance can be thought of as a state of equilibrium, or a state of equal changes between two sides. Flux can be thought of as a rate of flow or changes. Even small changes in an ecosystem's or population's balance and flux could lead to disaster.

Numerical Simulation of Magnetic Flux Emerging Through a Model Solar Atmosphere: Density, Magnetic F
This animation is one of a series depicting the results of a two-dimensional ideal magneto-hydrodynamic simulation of magnetic flux emerging through a solar atmosphere. The simulation has a resolution of 300x500 cells and a length scale of 16 Mm x 6.8 Mm. The simulation depicts 1730 seconds in the evolution of the model.
Great Zoom into Siberia
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl
Cumulative Earthquake Activity from 1980 through 1995 (WMS)
This animation shows a cumulative view of earthquake activity for the whole world from 1980 through 1995. Each dot on the image represents the number of earthquakes with magnitude greater than 4.2 that have occurred in a 0.35 by 0.35 degree area of the globe since January 1, 1980. A yellow dot represents 1 or 2 earthquakes, an orange dot represents about 10 earthquakes, and a red dot represents 50 to 200 earthquakes. The background image, if present, shows the topography of the ocean floor. As t
