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)

Evryoneone in different group helping in making of posters!!!

All of them carring a serious face while working.

Everyone from different groups working hard to finish our touch-up.

~Group Meeting!~

Today we meet at school to discuss the project.

As we were doing so over 10 water snails and a Damselfly nymph were captured.

We concluded that it was not a mosquito,

as it does not float up to the surface for air.

We also concluded that it could not be a Dragonfly Nymph,

as its body was too big to be the pest in our tank.

And with the consulting of some Green Club Members we were able to find out that it was a Damselfly nymph

~Congrats!~

Congratulations!

Our team has been selected to represent our class!

We have noticed that there are water snails in our tanks,

we are planning to remove as soon as possible

as they might eat the aquatic plants.

Updates: The water snails had been remove.

2 new fish have been added into the tank.

Now there is a total of 11 fish.

Both of the new fishes are female.

This is a report.

Due to the lack of knowledge of rearing pregnant fish, one of our pregnant fish died.

(It died on 13th May)

The pregnant fish was left in a pail filled with fresh tap water and a very strong air pump.

However, the tap water in the pail should be either left in the open for 1 ~ 2 days or water from the fish tank.

No air pump should be left in the pail as it would scare the pregnant fish and prevent it from giving birth with ease.

A few weeds should have been placed to allow the newly born guppies to hide from their mother.

Recently we have discovered that before the pregnant fish was isolated it gave birth to one baby guppy. It was discovered only today (15th May)
The fish had developed a small tail and has darker eyes than a new born guppy should have.

Now there are 10 fishes.

Plant measurement and Double-Check

We changed the piece of wood ( in the tank ) with a bigger piece to make the tank less empty.

This plant is about 17.9 cm long/tall (from stem to leaf) and it had grown 0.8 cm longer.

This plant is about 14.7 cm long/tall (from stem to leaf) and it had grown 0.2 cm longer.

This two plants (shown above) are the plants we are going to measure every week to see if it is growing healthy.
Doulble-check on our project
Plants: Growing well, none going to dry up...
Fishes: Strength:9 Present 9 ;All healthy
Water pump: Working good, no problem with it.
Air pump: Working good, no problem with it.
Lamp: Working good, no problem with it.
Ornaments: All in good condition.

New plants and "reuse" of plants

The "reuse" of the rooted aquatic plants...

Making the money plant firm...

Our sign to ask people not to touch the tank and the lamp

Plants damaged

The leftovers of the aquatic plant.

The aquatic plant was pulled out.

This is a picture of our damaged aquatic plant.

This is a picture of one of our 2 aquatic plants, it was pulled out from the pot.

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

Today, 7th May 2008, our system -Water pump system, the plug was unplugged so there is no water for our money plant but luckily none of the plants had dried up.

-Lamp, the lamp was found to be switch off and so the aquatic plants had no light to photosynthesis.

-Aquatic plants, 2 of our aquatic plants was found to be damaged as it was pulled out leaving it roots in the pot.

Suspects: People had damaged our system on 5th May as we had made a last chcek to make sure that all our system are working well. Before leaving the system: Water pump-Was switch on ; Lamp-Switch on ; Aquatic Plants- No problem with it.

Total damaged cost: 2 Aquatic plants- $2

We are going to buy 2 more new aquatic plants tomorrow- Amount spent- $2

Plant measurement and Double-Check

This plant is about 17.1cm long/tall (from stem to leaf)

This plant is about 14.5 long/tall(from the stem to leaf)

This two plants shown here are the plants we are going to measure every week to see if it is growing healthy.
