The Mole
You probably remember the mole from high school chemistry, but do you remember why it is useful to chemists? The goal of the following video is to give the "big picture" of the mole and its applications; information on how to use the mole in calculations can be found in another tutorial. Throughout this course, we will use the term "molecular weight" to refer to the mass of a mole of a substance (for instance, the molecular weight of oxygen (O2) is 32 g/mol). Recent textbooks refer to this as "m

Lunar Lander
Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Posterior Fossa Tumor - Station and Gait Exam - Gait Sub-exam - Patient 9
Patient is a 58-year-old white male with a history of acoustic neuroma that was resected in 1990. He has residual cranial nerve palsies on the right side and experiences tremors, ataxia and disequilibrium. His wife reports that she has noticed an increase in right hand tremor for the past year or so. The tremor worsens as the day progresses and occurs with activity. Patient reports an increase in balance problems while standing over the past 4 months. He has noticed that he staggers a step or t

Pendulum on an Accelerating Train Model
The EJS Pendulum on an Accelerating Train model displays the model of a pendulum on an accelerating train. The problem assumes that the pendulum rod is rigid and massless and of length, L = 2, and the pendulum bob is of mass, m = 1. The initial pendulum angle and the initial velocity of the train can be changed via textboxes, and the acceleration of the train can be changed via a slider.

Symmetry Breaking on a Rotating Hoop
The Rotating Hoop Launcher package shows the dynamics of a mass that is constrained to move on a rotating hoop. The rotating hoop model is an excellent mechanical model of first- and second-order phase transitions. Although the minimum of the potential energy curve corresponds to the bottom of the hoop at low rotation frequency, a spontaneous symmetry breaking (cusp catastrophe) occurs as the frequency is increased. This package presents the theory, a demonstration, and an Easy Java Simulation (

Professor Sir Michael Marmot in conversation with ANU academics
The economic, social and environmental determinants of human development and health equity. Three internationally renowned speakers discuss how environmental, political, economic and cultural characteristics of societies shape conditions in which people live, work and age. Inequities in these factors play a major role in producing health inequities in Australia, across the Asia Pacific region and globally. If set up well, economic development, trade, working conditions, urbanisation and healt

Newton Rocket Car
The purpose of this activity is to demonstrate Newton's third law of motion which states that every action has an equal and opposite reaction through a small wooden car. The Newton cars show how action/reaction works and how the mass of a moving object affects the acceleration and force of the system. Subsequently, the Newton cars provide students with an excellent analogy for how rockets actually work.

Map Your World
Map Your World is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about plans by mapping their rooms. The activity begins with a brief explanation of the variety of maps we use, explaining how archaeologists use plans. Kids are then given step-by-step directions for creating a plan that shows their room and its contents. Directions for two additional activities are included, Map a Bigger World and Map Your Room to Scale.

Inelastic Collision of Particles with Structure Model
The EJS Inelastic Collision of Particles with Structure model displays the inelastic collision between two equal "particles" with structure on a smooth horizontal surface. Each particle has two microscopic elements which interact through a massless spring of stiffness k and natural length L. The mass of one of the microscopic elements and the spring length of the connector spring can be changed via textboxes. You can modify this simulation if you have EJS installed by right-clicking within the p
