5. Conclusion

Key findings

After lots of launches, we have gathered the results together and found out that the best ratio of baking soda to vinegar to for the furthest distance of launch is 100:250.

Explanation of key findings

After testing the various ratios of baking soda to vinegar, we have found out that the ratio of 100 grams of baking soda to 250 milliliter of vinegar allowed the rocket to travel the furthest distance of 18.35 meters as all of the baking soda was able to dissolved completely. This allowed the maximum pressure to build up and to launch the rocket the furthest unlike the other ratios where there was too much baking soda to dissolve or too little baking soda to mix with with the vinegar to launch the rocket forward. 

Evaluation of hypothesisAfter the experiment we concluded that our hypothesis was wrong as when using the ratio of 150:200 of baking soda to vinegar, the amount of baking soda was not able to dissolve completely in the vinegar. Thus the ratio 150:200 was not able to launch very far but the ratio 100:250 was the best.


Conclusions 
In conclusion, our hypothesis was wrong, instead of a ratio of 150 grams of baking soda to 200 milliliters of vinegar , the ratio which resulted in the furthest distance reached is 100 grams of baking soda to 250 milliliters of vinegar.


Summary of findings 
We found out that in order to have the rocket to be launched the furthest, all of the baking soda must dissolve in a sufficient amount of vinegar so that there will be more pressure and thus the rocket will be launched the furthest. This is why the ratio of 100 grams of baking soda to 250 milliliter of vinegar chemical reaction launched the rocket the furthest and proving our hypothesis of 150 grams of baking soda to 200 milliliter of vinegar that will launch the rocket the furthest wrong.
