We Would like to thanks all those who had supported us for this project.

This project had successfully ended.

This blog will no longer post any more pots about the project but you all can still visit and view our blog.

Thnak you so much again for your great support!!!

EE last moments video- summary for the whole project

This video is a summary of our whole project.

WE would like to thanks Mrs Annie Lim for her guidance and care.

And also other supporters for either the video or the whole process for the project!!!

We hope you would enjoy this video!!!

new discoveries and dead fish

This is a report.
We found a dead fish ( female) on 25th June 2008 .
How it died? : We suspected that it died because of not being able to blend in to the new surrounding so it died.

We found this egg like thing around the pot of plant and we suspected that it is either a water snail egg or is a earth worm egg.

Attack of water snails and others

As you can see, the log had been attack by about 20 to 30 water snails.

The picture above shows a damselfly nymph. It was found dead outside our fish tank.

*The pictures might not be clear. We are sorry for the low quality of the pictures.

--------------------------------------------------------------------------

After the school reopens, we had found out that our system had been invaded by the water snails.

There was about 100 water snails found living in our fish tank.

For the safety of the fishes and the system, we had changed the water and the gravels that had alot of water snails living in it.

Till now, the almost all of the water snail had been removed and the tank is clean for the fishes to live in.

We had planned to get 2 more new aquatic plants to replace for the ones that had been invaded by the water snails.

More information about the attacks of the water snails will be stated in the next post.

Feeding of our fishes

Members of EE group 2, if you are available in school from 9-11am please help us feed the fishes at the physics Lab 1.

Thank you.

Congratulations!!!

Congratulations to our 1/5 team 2!!!
We had got 3rd place for the final judging!!!
All the hard work finally had been paid off!!!
*Special thanks to all those who had supported us!!!

Different in light

An example of fluorescent light!!!

Example of Tungstun

Tungstun and Fluorescent which one is better?

After some research, we had found out that Fluorescent light is better as it is more efficient than Tungsten light bulbs of an equivalent brightness. This is because a greater proportion of the power used is converted to usable light and a smaller proportion is converted to heat, allowing fluorescent lamps to run cooler.

Tungsten light has the highest melting point (3,422 °C) (6,192 °F), lowest vapor pressure and (at temperatures above 1,650 °C) the highest tensile strength. Tungsten has the lowest coefficient f thermal expansion of any pure metal. Alloying small quantities of tungsten with steel greatly increases its toughness. ( Overall Tungsten produce more heat)
