When we pick up a can of hairspray, how do we know it's safe for us to use it? How did the manufacturers know how much haircare material and gas to pump into it to ensure a controllable release? What about a pressure cooker, the propane tank in the kitchen, or the tires of a car?

We take these thing for granted. But have we ever wondered about laws that govern them?

Where do we get our energy from? Most of you would say food, carbohydrate, or sugars, which is right. But those answers may be enough to satisfy a preschooler, not those taking biology, or having even the mildest interest in its branches.

A simple question sometimes require an extensive answer, and this being the study of life, the answer is never simple.

Here's a question. When you've figured out how the building blocks of universe works, what's the first thing you do with that knowledge? The obvious answer: make better versions of the universe itself. Humans have been doing that since the dawn of civilisation: we built monuments using, at first, stone, then bricks, then concrete, and finally steel.

Making better things had always been the prime mover of our ascent to civilisation. And we're still doing it today. That's where material sciences come into play...

For many of us, chemistry is about mixing chemicals, balancing equations, and endless measuring. But there's also an artistic, aesthetic, even philosophical appeal to it.

Precipitation reactions were used in this sense, but of course understanding it is a prerequisite.

Secondary school Biology seldom go into the details, the structure of a cell is an example of this. We were taught that cells consists of the nucleus, mitochondria, chloroplasts, walls and such, but that's pretty much it. We bet that teachers could go deeper into the subject with no risk of confounding their students. We therefore challenge the teachers to add value to their syllabus, starting from the basics. 

Cikgus, make us proud and prove us right.
