Leaning Tower of Pasta
Using spaghetti and marshmallows, students experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments help them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension.

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

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.
By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.
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.
