Cause and effect.

We wrote a cause and effect sentence for each of our mechanisms 

I wrote the mechanisms for how chocolate is made and how fireworks work.

I wrote the mechanisms and used cause and effect to put inside the mechanisms. 

Chocolate:

Chocolate is made by roasting the cocoa beans and removing the nibs in order to blend it to form a liquid. You then pour it into a mold  so it can set. The  shape and size of your mold effects  the chocolate  that results   when you put the chocolate in the freezer to harden.

Fireworks:

Cylindrical paper containers are used in order to hold all the firework parts together.

The fuse is used to create delays in order for the firing of multiple firework displays.

The bursting charge is used when the explosion goes off; sometimes  stars are included with the reaction.

Next time, I should work on my mechanisms to add more information.
