An extended investigation bottle rockets

The mathematical formula gives the curve that best fits the experimental data within the error bars. Students should be able to: But you could do it with a bow and arrow, or a ball launched from a small catapult and so on. The dielectric is outlined as two rectangles in the image so you can see the edges.

You could do it with a plastic water bottle, a stopper or two and some glass tubing. For a flow of water as in the diagram above, the radius of the hydraulic jump Rj is related to a number of factors and exploring these would make a great EEI.

Do this by setting up the circuit on the left below, using either a variable resistor or fixed resistors that can be varied from 0 ohm to ohm. But note, the leads will get red hot.

Professional displays[ edit ] A common misconception about professional fireworks displays is that skyrockets are used to propel the pyrotechnic effects into the air. Further qualitative discussions about the validity of the law and the accuracy of the measure are then welcome.

A good EEI would be to measure current as a function of the angle of incidence of sunlight all within a short period of time eg 30 minutes ; measure current when collector is perpendicular to rays during the day how should that go?

He found the relationship to be: Resistance and temperature for non-ohmic sausages You can cook food by forcing an electrical current through it. It could be used in university physics. It consists of two wires of two different materials that are joined at each end. There are lots of things that would make a great EEI.

Some teachers have wisely said: Below is the plot of such an experiment done by my hero Prof. A 16cm long 6B pencil gave a current of 2. It is very difficult to find the equation for the non-linear curve so for Senior Physics, you may not wish to do so. For large-scale solar plants to maintain their maximum efficiency, the photovoltaic cells must be kept clean, which can be a challenging task in dusty environments.

Be sure to ask for them empty and clean! A potato gun is a "firearm". Once, students would do this prac using live ammunition. It was invented in by English mathematician Benjamin Robins to provide the first way to accurately measure the velocity of a bullet.

The relationship between capacitance and plate separation for a parallel plate capacitor is well known:Bottle rockets thrown at demonstrators in Westminster, police say The vehicle (pictured above) is described as an extended cab pickup truck, The investigation is ongoing.

A skyrocket is a type of firework that uses a solid-fuel rocket to rise quickly into the sky; a bottle rocket is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be ultimedescente.comed by: Polly Platt, Cynthia Hargrave.

In this activity, students make a water bottle rocket. They investigate the variables that affect the height and distance travelled by the rocket.

By the end of this activity, students should be able to: build a rocket out of a plastic bottle, using water and air pressure to generate the thrust.

This activity is a field investigation where students will gather data on speed, acceleration, gravity, friction, and forces. They will design and conduct an investigation. In this field lab, students will investigate forces using pop bottle rockets.

An Extended Investigation: Bottle Rockets. Topics: Force, Research Pop bottle rockets are used for the study of aeronautics all over north rockets are used in schools to help students understand the principles of aeronautics.

issues involved with building and launching bottle rockets. Safety is a major issue. Be certain that you study the accompanying “Safety Rules” with your students and monitor strict safety regulations during all launches.
