Application of the Hardy-Weinberg model to a mixed population of Bar and wild-type Drosophila
Unlike most population genetics labs, which involve simulations with beans or beads, this lab provides an opportunity to study a population of living organisms. Using Bar and wild-type Drosophila, students compare allele and genotype frequencies to Hardy-Weinberg expectations. Because the Bar mutation in Drosophila is sex-linked and incompletely dominant, students can determine the exact genotype of a fly from its phenotype. These data are evaluated to determine which (if any) of the five Hardy-
Animal Behavior Experiments Using Arthropods
This exercise is designed to familiarize the student with ethology, the study of animal behavior, by observing the behavior of several different arthropods.
Offshore Hydromechanics includes the following modules: 1. Hydrostatics, static floating stability, constant 2-D potential flow of ideal fluids, and flows in real fluids. Introduction to resistance and propulsion of ships. Review of linear regular and irregular wave theory. 2. Analytical and numerical means to determine the flow around, forces on, and motions of floating bodies in waves. 3. Higher order potential theory and inclusion of non-linear effects in ship motions. Applications to motio
Quantum Information Processing
Quantum Information Processing aims at harnessing quantum physics to conceive and build devices that could dramatically exceed the capabilities of today's "classical" computation and communciation systems. In this course, we will introduce the basic concepts of this rapidly developing field. Study Goals: To understand the operation, potential, and limitations of the main theoretical results (algorithms, error correction, communication) To be able to use the formalism of quantum information (uni
Seasonal Migrations: Whooping Cranes
Children follow the migrations of animals. They observe, research, and report their findings, and watch journeys progress on real-time maps. Through these interrelated investigations, students discover that sunlight drives all living systems and they learn about the dynamic ecosystem that surrounds and connects them. Fall: Students watch chicks grow and then "join" the migration as humans teach the birds a new route using an ultra-light plane to lead the way. Daily updates: September-December. S
Courtship Reaction Chains and Mate Attraction: A Two-Part Laboratory Activity Using WOWBugs
A laboratory exercise to study insect courtship behavior using Melittobia digitata, WOWBugs.
Discovering Devonian Microfossils
Microfossils are small, fossilized remains of organisms (animal, plant, or protozoa) that require magnification for study. They usually derive from the hard parts of organisms (skeletons, shells, jaws, teeth, seed coverings, etc), and may be imbedded in rock or exist as loose particles within soft substrate. Research studies of microfossils provide insights into ecological and evolutionary relationships among plant and animal communities that existed on earth hundreds of millions of years ago. M

Submarine Volcanoes of the Western Pacific
The way the sea floor is mapped has been revolutionised in the last decade by high resolution, multi-beam sonar systems, with follow-ups by manned and remotely-operated submersibles. Using these techniques, research groups from Australia, Germany, New Zealand and the USA are discovering much more about chains of underwater volcanoes in zones of tectonic plate convergence, known as 'arcs'. Researchers have found that up to 40 per cent of these underwater volcanoes in the southwest Pacific Ocean a
It’s Every Monkey for Themselves
Taking off to mend a broken heart, Vanessa Woods left safe, suburban Canberra and headed for the remote, wild and distinctly unsafe jungles of Costa Rica. She was stung so often by killer bees she developed a lethal allergy, and the monkeys she was to study were evasive, mean and aggressive. The only difference between them and her housemates was that at least she could tell her housemates apart. In this talk, science writer Vanessa Woods will explain how to survive a year in the jungle: a world
Mars Reconnaissance Orbiter: The First Months
NASA's Mars Reconnaissance Orbiter (MRO) was launched in 2005 to search for evidence that water persisted on the surface of Mars for a long period of time. While other Mars missions have shown that water flowed across the surface in Mars' history, it remains a mystery whether liquid water existed long enough to provide a habitat for life. After a year’s cruise and aerobraking to reach its science orbit in September 2006, the MRO has begun to study the history of water on Mars with a suite
The New Horizons mission to Pluto and the Kuiper Belt
New Horizons is the first scientific investigation to obtain a close look at Pluto and its moon Charon. Scientists hope to find answers to basic questions about the surface properties, geology, interior makeup and atmospheres on these bodies, the last in our solar system to be visited by a spacecraft. The mission could also visit one or more Kuiper Belt objects. New Horizons launched on January 19, 2006. It will swing past Jupiter for a gravity boost & scientific studies in early 2007
An Underground River
Groundwater is one of the largest sources of drinking water, so environmental engineers need to understand groundwater flow in order to tap into this important resource. Environmental engineers also study groundwater to predict where pollution from the surface may end up. In this lesson, students will learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow.
May the Force Be With You: Thrust
In this lesson, students will study how propellers and jet turbines generate thrust. This lesson focuses on Isaac Newton's 3rd Law of Motion, which states that for every action there is an equal and opposite reaction.
May the Force Be With You: Weight
The purpose of this lesson is to help students understand the relationship between the mass and the weight of an object. Students will study the properties of common materials and why airplanes use specific materials.
4 Summary of video
The search for new medicinal products is one of the major driving forces behind the development and application of new synthetic methods. This unit focuses on a specific case study, which follows the development of a drug for the treatment of high blood pressure. It is a particularly good example of the application of organic chemistry in the pharmaceutical industry, and illustrates the scientific processes that are involved in the development of any new drug.
Surviving the winter
In this unit, we study one aspect of the fluctuating nature of an organism's environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source o
