conflicting interpretations of the nature of the Meers fault. All studies of the fault -trenching (Crone & Luza, 1986), shallow seismic (Miller et al., 1982), magnetic profiles (Cecil-Jones, 1990) and coring (Collins, 1992)- indicate the fault is a reverse fault that dips steeply north into the. Anadarko basin.
Egg drop competition. A package designed to protect three eggs from a fall of ten meters is dropped by a physics teacher on a lift. The egg drop contest is an experiment usually performed by college or primary school students. Competitors typically attempt to create a device that can keep a raw chicken egg intact when dropped from a height.
Learners can vary the mass of the egg that is dropped, the height from which it is dropped, and the surface onto which it is dropped. The egg drop is simulated and the result is displayed. The impulse-momentum change theorem is used to show how the force is calculated from the egg drop parameters that are selected. The Interactive provides a eggcellent demonstration of how alterations in one variable affect another variable. Users are encouraged to open the Interactive and explore.
