HELLO. :DDDD

Got back from school yeah.
Today's lesson is still the best for the week. Environmental technology. :DDDD

Today did the rest of the chapter on the air pollution thingy . And guess what? Another test .
Test on whole book on the 13TH NOV . Well, at least it is on the 13th i don't mind another test . :PPP
Okay, seriously what am i thinking ? TEST LEH !!! I must be siao liao.

I forgot i got how many chapters liao. But it doesnt matters right? Still have to study. T_T

Then today i did the most ridiculous test ever . The PE written test . Only 15 questions and what they asked is lame questions . Like soccer, basketball , why we must have PE , What are the benefits of having PE .
SHIT CAN . Waste my time only. Then the questions on the soccer and basketball thingy i didn't know the answer then i asked jia jie . And jia jie still can ask me other question what i put. LOL !!
And the teacher is right in front of us . -_-''''

Crap loh. It is for the test then i go PE de. If not i already skip liao. The PE test is counted for the final exam . -_-''''

Alright, anyway today's EVT practical is so fun la !!

Today we did a new experiment . Testing the water hardness. Firstly we have to get water from , well any place you want and just drop in the chemicals given and ta da your water will change into the colour of purple just the one above and your test is done.

This test is basically testing out how much content of calcium it contains in the water sample.
You can just get water anywhere you want from the toilet also can , etc ,etc . And you have 3 bottles of chemicals you drop in the first and second and you will see the water change to red and later you drop in the third one your water will change to purple .

My team got the water from the library pond. Some of them got the water from the toilet bowl and some at the water coolers , swimming pool ,etc ,etc.

Plus the water from the toilet bowl really got some colours de leh. Damn gross la . It is so brave of vicky to get it from the toilet bowl. :P

Above that picture is rayan with our water sample . :DD The colour purple so cute hor ? HAHA . LOL.

And one bad thing about this test is that it cannot test out with coloured water ( blood, mud water ,etc ) but only colourless water . It is using the colour indication to do the test.


Okay, got home a little bit early . Tomorrow got test. Yet again . BYE :DDD
