Thanks Cody, you have put heaps of effort into your Science Fair project (I imagine you had fun completing your experiments). You have also put in some good research and have a good understanding about the how/why the gases were created, it is pleasing that you understand the 'Science' behind the experiment. It would be interesting to go through the process again with larger containers to see if the ones that when off quickly could be measured??? Well done Cody, you should be proud of project :+) Although you did not keep a log book I could see that you kept a table of results and included websites used in parts of your project. **Student Comment:** I think I did well on my science board but I'm just happy I finished **Rocket fuel** I chose this topic because it sounded like fun and I already have some idea of how toy rockets are pushed into the air. I know the ingredients that are used to fuel toy rockets cause a chemical reaction when they are combined making the rocket shoot up.
 * Teacher Comment:**
 * Introduction**

My Aim is to discover which ingredients propel a toy rocket into the air the highest. I think that the coke & mentos will work the best because it has a more violent reaction. I don’t think that baking soda & vinegar will work the best because in a baking soda & vinegar volcano it just flows over the edge.

 * Hypothesis**

.timer .coke .mentos .baking soda .vinegar .aspro clear tablets .water .film canisters
 * Equipment**


 * Method**
 * 1) get equipment shown on the list
 * 2) choose first ingredients - coke & mentos
 * 3) fill canister half way with coke
 * 4) put one mentos in with the coke
 * 5) quickly put lid on canister
 * 6) turn canister upside down
 * 7) time from moment canister is turned over
 * 8) turn timer off once it explodes and time from moment it explodes to the moment it lands
 * 9) turn timer off once it lands
 * 10) record results
 * 11) fill canister half with coke again but this time put in 2 mentos
 * 12) repeat steps 5-10
 * 13) fill canister half with coke again and this time put in 3 mentos
 * 14) repeat steps 5-10
 * 15) Change one variable - replace solid ingredient e.g mentos replaced with aspro clear tablet
 * 16) repeat steps 3-13 with aspro clear tablet
 * 17) Change one variable - replace solid ingredient e.g aspro clear tablet with a teaspoon of baking soda
 * 18) repeat steps 3-13 adding 1 teaspoon of baking soda each time
 * 19) choose second liquid - vinegar
 * 20) repeat process 3-18
 * 21) choose third liquid - water
 * 22) repeat process 3-18

**Thanks Cody, you need some more detail in your Introduction, Aim, Hypothesis & Method (Nex****t time copy & paste so that I can help you with editing).**

**Introduction: I enjoy makings interesting toys and am curious about how high I can make a rocket fly ...**

**Hypothesis: I think that using ... as a fuel will work the best because .... I think that ... will not work very well because ...**

**Method: Cody remember the procedures we wrote last term. You need to elaborate on what to do so the reader would be able to follow the instructions.**

**Come and see me & I'll help you with this.**

**Remember only change 1 variable at a time e.g. use the same rocket for each fuel. Once you have found the best fuel then you could try different rockets with that fuel.**
