Mechanisms

 We learned how to write an explanation using mechanisms.

First, we wrote a mechanism for how chocolate is made.When the ingredients are combined and melted, they make a liquid.

Next, we wrote another mechanism. If you use a mold it will shape the liquid.  You then cool it so it will set. The finished chocolate is in the shape of the mold you used and sets when it is cooled.

Next we wrote a mechanism for how fireworks work. Gunpowder is packed in a very tiny space as a result it burns really fast. Potassium is the most important part of gunpowder. This is what propels the fireworks into the sky. The fuse is set alight and as it burns it ignites the gun powder. This happens slowly so you have time to move away from the firework anf thertefore you can stay safe.

Next time, I should work on my mechanisms.
