Is it possible to collect micrometeorites from the outdoors?
Collect micrometeorites from indoor and outdoor sources.
What causes a tsunami? Demonstrate this with a model
A Tsunami (Japanese for 'harbour wave') is a wave generated by an undersea earthquake,landslip or volcanic eruption so if you want to demonstrate what causes a tsunami rarher than it effect that it may have then we have to think about simulating an undersea earthquake.
How to create an electrostatic charge using a handheld electrophorus
A hand-held electrophorus can produce significant amounts of charge conveniently and repeatedly. It is operated by first frictionally charging a flat insulating plate called a "cake". In Volta's day, the cake was made of shellac/resin mixtures or a carnauba wax film deposited on glass. Nowadays, excellent substitutes are available. TeflonTM, though a bit expensive, is a good choice because it is a
How to generate enough static electricity to create sparks
In this experiment we'll create an object called a electrophorus (greek word for charge carrier). Using the materials listed above, we'll charge the object and then discharge it creating a snap, a little electrical shock, and a bright spark. If you're afraid of a little electrical shock then get Dad to discharge the object for you. And for grins, don't tell Dad beforehand about the resulting sp
How does a change in temperature affect the current, voltage and power generated by a solar cell?
The purpose of this experiment was to determine how different temperatures affected the voltage (mV), the current (mA), and the power (watt) generation of a solar cell.
Does the number of turns of wire in an electromagnet affect its strength?
The purpose of this experiment was to find out if the number of wire wraps will effect the amount of iron filings an electromagnet picks up.
How to build a lightning storm detector (Franklin's Bells)
The toy is a high voltage motor that acts like a bell, with a clapper that bangs furiously from one can to the other and back again, sometimes several times per second.
What is the most efficient angle for windmill blades?
My first hypothesis is that the closer the blade is to 45 degrees the more electricity the windmill will produce.
How to suspend a ball in a stream of air (The Bernoulli principle)
A ball stably levitated on an invisible stream of air is a dramatic sight. When you try to pull the ball out of the airstream, you can feel a force pulling it back in. You can alsofeel that the airstream is being deflected by the ball. This Snack shows one of the forces that give airplanes lift.
Can we create light by chewing?
Certain chemical bonds will generate light energy when the molecules are torn apart by mechanical crushing. Wintergreen Lifesaver candies contain some of these bonds. No other flavor of lifesaver candy (such as peppermint) will work in this experiment.
