Lighthouses
A lighthouse is a structure used to house a light source that acts as an aid to navigation for those at sea. It can also use a sound source for warning. They are also used to warn of dangerous coastlines, reefs, and other hazards, while indicating safe entries to harbors. Most remaining lighthouses are automatic rather than being manned. Questions should relate directly to all aspects regarding lighthouses, including their use and history.

Why are police cars painted black and white?
This goes back in history, as many were painted this way to be conspicuous to the public. Easy to recognize, and public awareness.
It's a long standing tradition. People like it.
Depends on where you are: there are no black and white police cars in Australia. Most are white with blue markings (blue and white checks are associated with police in this country) while highway patrol cars are often unmarked and in whatever colours come from the manufacturer. Some patrol cars are factory colour plus dayglow strips (presumably for visibility) with another strip in blue/white checks. This varies from state to state, too.
AnswerBlack and white police cars usually have the doors white, and front and rear clips black. that way they will be more visible when the vehicle is parked at a right angle to the freeway. and so the vehicle can be less visible when parked parallel to a road. you may notice that when a black and white police vehicle willl pull someone over, they will park the police car at a angle slightly to the left of the road to make the white doors more visible.What is a good scientific method?

A thermo time switch is a temperature sensor device normally used to turn on a cold start injector in German cars. The cold start injector is an extra injector normally mounted in the intake manifold. The thermo time switch will allow current through it to your cold start injector for a few seconds ( 3 - 8 depending on the make and model of car ) when the engine is cold and first started. This puts extra fuel in the system and helps it start. If your thermo time switch fails you may have a hard time starting when cold or, more commonly, a difficult time starting the car when hot. The problem in the latter case is the extra injector flooding the car when trying to start it.
Describe why a thermostat is an example of a feedback loop?
because a change in one factor (the temperature) causes a response that brings that factor back to normal.

How did the early humans make canoes?
Early humans made canoes two ways, depending on the culture.
1. By burning out the inside of a fallen log and using bone or flint tools to periodically scrape away the burnt wood.
2. By using metal tools to chisel out the inside, and often the outside for a smoother finish. The canoe might then be covered in hot tree sap which, when hard, waterproofs the finished boat
