title:{science project....}

Starting my science projects today.Doing only 1/4 of it,it was quite fun to research on the topics esp the 'shooting stars' and the machines to detect ghost.I am quite excited to see Jasmine presentation cause her topic is very interesting.Lol.... eng peng is actually wanting to do one of my above topics but she heard me saying that I do the research on that tat topics.She then abandoned the idea......

Do not know how Hui Hui and they all is faring in their phy project....

title:{one of the machines use to detect ghost...}

Electro-Magnetic Field Detectors (EMF Detectors) can pick up electronic fields over different frequencies. Their purpose is to detect the presence of electro-magnetic fields. Such fields can be generated by ghosts and has been related to haunting activity. Where there are ghosts there are usually disruptions in the electronic field. The frequency sensitivity range can vary greatly between models. Our devices can detect between 20-10,000Hz, while some others may detect only between 40-60Hz. An audible alarm is integrated within. This will inform us of an EMF detection without having to keep your eyes on the device.

I do not know to choose either machines to detect ghost or 'shooting stars'.Anyway,I have done some research on shooting stars .......Shoooting stars ..............

What causes a "shooting star"?
A "falling star" or a "shooting star" has nothing at all to do with a star! These amazing streaks of light you can sometimes see in the night sky are caused by tiny bits of dust and rock called meteoroids falling into the Earth's atmosphere and burning up. The short-lived trail of light the burning meteoroid produces is called a meteor. Meteors are commonly called falling stars or shooting stars. If any part of the meteoroid survives burning up and actually hits the Earth, that remaining bit is then called a meteorite.
At certain times of year, you are likely to see a great number of meteors in the night sky. These events are called meteor showers and they occur when the Earth passes through the trail of debris left by a comet as it orbits the Sun. These showers are given names based on the constellation present in the sky from which they appear to originate. For example, the Leonid Meteor Shower, or Leonids, appear to originate in the constellation Leo. It is important to understand that the meteoroids (and therefore the meteors) do not really originate from the constellations or any of the stars in the constellations, however. They just seem to come from that part of the sky because of the way the Earth encounters the particles moving in the path of the comet's orbit. Associating the shower name with the region of the sky they seem to come from just helps astronomers know where to look!
