Magnetic Pole Reversals
Bernard Brunhes' study of volvanic eruptions led to the discovery of the Earth's magnetic field reversal. This 2:34 long video explains how his work revealed that the Earth's magnetic poles had reversed itself. Some evidence that the same thing happened on Mars.

In Syrien geht die Armee weiter mit großer Härte gegen Gegner des Regimes von Präsident Baschar al Assad vor. Nach Angaben von Menschenrechtsaktivisten rückten Regierungstruppen weiter auf Dschisr al-Schogur im Nordwesten Syriens vor, einem Zentrum der Auseinandersetzungen zwischen Regime und Opposition. Die

Killdeer eggs
Killdeer are birds, and they lay eggs just like all other birds do. Killdeer lay their eggs on the ground, in gravel, on rooftops, or wherever the splotchy pattern of the eggs may be hidden best. The eggshells are hard for added protection.

The Neural Tube Development module answers the following questions: 1. What is the shape of the neural tube when neurulation is complete (i.e. when this animation begins)? What is the neural canal? What is the shape of the neural canal? 2. What are the basal and alar columns? What will they eventually develop into? What is their shape and extent along the neural tube? and their initial position relative to the neural canal? 3. Where along the neural tube are the prosencephalon, mesencephalon, an

This unit introduces the topic of differential equations. The subject is developed without assuming that you have come across it before, but it is taken for granted that you have a basic grounding in calculus. In particular, you will need to have a good grasp of the basic rules for differentiation and integration.
This unit looks at complex numbers. You will learn how they are defined, examine their geometric representation and then move on to looking at the methods for finding the nth roots of complex numbers and the solutions to simple polynominal equations.
This unit examines the area of the brain based learning with a particular focus on the development of the young child's brain and is of particular relevance to those who work with young children. We begin by looking at the structure and functions of the brain, and the impact that sensory deprivation can have on these. We consider the implications of current understandings of brain development for teaching and learning, particularly in an early years setting, and finish by exploring the value of

This interactive article looks at research findings over the past few decades that concludes birds are, in fact, a kind of theropod dinosaur. The article includes the following: An overview explaining how scientists identify and classify new specimens; An introduction to the finding that theropod dinosaurs, like Velociraptor, are more closely related to modern birds than they are to almost any other kind of dinosaur; A detailed answer to the question, What is a theropod? An interactive that allo
This exercise illustrates to introductory level students that Mendelian patterns of inheritance can be studied using biochemical assays as an indication of biochemical phenotypes. Students investigate the pattern of inheritance of aldehyde oxidase in different strains of Drosophila. Using this information, they study progeny from a mating between unknown parents, develop hypotheses about the parental genotypes, and investigate the results using chi-square test. In addition, students determine th
