改編歌詞（EP.1)

我這個學霸（每一次考試也是4.0+/5.0）有特別的溫習方法，就是改編歌詞。以下是我的其中一些歌曲：
1. Water as the usage in organisms(原曲：春田花花幼稚園校歌)
Organisms are mainly made in water,
It makes 60% of our weight,
And 98% of that in jellyfish,
It serves a lot of functions.
In plants it’s a reactant in photosynthesis,
In humans it can break down complex food
In the digestion of it.
It is also a very good solvent
That can dissolve many substances,
When they are dissolved they are carried
Around the body in blood.
It also acts as a cooling agent
Like in high temp we produce sweat,
It also gives shape and provides support
To some kind of organisms.

2. Diffusion and osmosis(原曲：黃昏放牛）

Substances move across membranes
By four different main ways,
The first one is diffusion
It’s here in concentration gradient,
There will be a net movement of particles
From high to low concentration
Until the particles distribute evenly,
It is a passive process.
Greater difference in concentration,
A high temp, and a smaller size,
A short distance and large surface area,
Is the best time of diffusion.
It lets cells to exchange
Materials with the environment,
Those substances which are in the cells
Distribute through the cytoplasm.
Osmosis involves the movement of
Water molecules across a differentially permeable membrane,
There will be a net movement of water molecules
From high to low water potential,
If animal cells are put in hypotonic solution,
It will swell and finally burst,
If it is put in hypertonic solution,
It will shrink and become wrinkled.
If a plant cell is put in hypotonic solution
It will become turgid.
If it is put in hypertonic solution,
Plasmolysis is here and it’s flaccid
When both are put in
An isotonic solution
There will be no net gain or loss of water
So it’s volume will remain the same.

3. Food Test （原曲：放不低）


Dip a piece of glucose test paper in glucose solution,
It will turn from a pink colour to dark blue,
When you mix it with Benedict's solution and put it in high temp(temperature)
A brick red precipate will appear,
So it's reducing sugar and sucrose isn't one,
If you work the same with it there is no reaction,
As a brick red precipate will indicate that
Reducing sugar is here,
When you add a drop of iodine into a drop of starch,
It will turn from a brown colour to blue black,
When you add a drop of lipid to filter paper and then add alcohol
There's a translucent spot and it will disappear.
（間奏）
When you mix oil and water in a test tube,
The oil layer is on the surface,
As lipids always float on water at any time,
This is the suspension test,
*If you dip a piece of protein test paper into egg white,
It will turn from a yellow colour to a green one,
If you put vitamin C into DCPIP,
It will become decolourized.
(重唱*)
This is how we test for different food substances.
