A Chemical Reaction is a process in which one or more substances change into one or more new substances.
- Chemical reactions involve energy
- Energy is either absorbed (Endothermic) or given away (Exothermic)
Chemical Equation:
An empirical representation of a reaction can be arranged
Ex. NaCI + KBr---->KCI + NaB
Read: Sodium Chloride reacts with Potassium Bromide to produce Potassium Chloride and Sodium Bromide
Looking Beyond-
Here is the equation for today's reaction you don't have to use this exact amount grams for the reaction to occur, but the percentages of these chemicals are needed so as long a you dialectal the percentages into 26% and 74%
We will be performing a reaction in this experiment were we will be making and igniting a bottle rocket.
A bottle rocket made very similar to a rocket engine with an additional skewer attacked to the side to hold it up. It is simply made to propel itself up with a sudden burst of thrust from a lit fuel of rocket fuel or black powder.

Materials-
- wooden doll
- aluminum foil
- regular notebook paper
- tape
- rocket fuel
- marshmallow stick
- fuse
Launch prep
- We were given little wooded dowels
- I wrapped mine in regular note book paper
- I wrapped that paper completely with tape
- Then I cut the edges so that they would be even
- I took a small piece of aluminium foil and rolled it into a little football so it could fit in one of the sides of the tube of tape I had made
- Once I had it in I used the dowel to compress the aluminium down; I hit it on the table a couple of times to make sure it was in tight
- In the other side I poor some rocket fuel Andrew (Best Teacher Ever) made
- I used the dowel in the same way to compress the fuel
- And again I sealed the other side with aluminum foil
- Jenessa helped me use a drill bit to make a hole half up the cylinder
- I then inserted a fuse
- Finally I taped a marshmallow stick to the side and went outside
Looking Inwards-
With my field test rocket motor I went outside with the others we each launched our own most didn't leave the ground, but might went up about ten feet from the ground a success. My one mistake was that I didn't record it I had a friend do that but they lost the video so here is a video of what basically happened
Looking outwards-
I did this lab by myself mostly Andrew made the rocket fuel and Jenessa helped me with the hole for the fuse. I appreciate both them for their help.
Looking Forward I want to continue doing rocket projects they are fun and exciting.
