Science Olympiad is set up as a competition in the same way a track competition is set up. Competitors extensively train for each of their events for several months beforehand in order to perform well on competition day. There are 23 events that cycle through each year to accurately represent the scientific challenges society faces today. For example, there are many events for renewable energy or eco-friendly technology in response to the ever growing threat of global warming. These events such as wind power or electric vehicle would be considered build events as they require hands on experience to build well thought-out

is the air resistance on any given object that is moving in the presence of air. In the

in accordance with a simple relationship, he could explain the fall of objects to the ground,

1. Find the westward component of a resultant vector 85.42 unit, 23º W of N.

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

10 Use test print to determine best 2nd exposure (white light) time and process as usual.

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

3. Measure and mark 30cm on the ramp with tape. This will be our effort distance.

Newton's first law of motion, states that anything that is in motion remains in motion until acted upon by an outside force, for example gravity. Also anything at rest will remain at rest until acted upon by an outside force. This means that anything that is moving will keep moving until you or something else stops it and that anything lying still will remain still until you or something else makes it move. Before we launched the rocket , it was just sitting on the pump. It didn't move until we pulled the

The flyer begins this move with their center of gravity 4 feet above the ground. One is thrown with an initial vertical velocity of 30 feet per second.

In figure 1, the force of the gravity is pulling the person and the parachute towards the ground because gravitational force makes the object fall quickly. However, the parachute slows the person down because it causes air resistance as it pushes the parachute back up and creates an opposite gravitational force. The forces “push or a pull” are called action and reaction forces, the subject of newton’s third law. During this investigation, the push force is the air resistance and opposite (pull) force is the gravity.

The objective of this practical is to determine acceleration due to gravity ‘g’ using the simple pendulum model. This is shown when a period of oscillation is seen to be independent of the mass of the mass ‘m’.

3) In this experiment, only the forces on the plane surface were considered. Do the hydrostatic forces on the curved surface of the quarter-circle block affect the measurement? State why or why

Theory states that T and d are related by the equation: T2 = kd3+ (4π2 l)/g where g is the acceleration of free fall and k is a constant.
