Obervations.
Our experience with our cannons with quite the thrill even though they ended up not working the excitement of making them was great. Once we built our cannon we later on during the week took them outside in front of our school to fire them. We used ethanol and a wood splint to fire them this would be the combustion reaction that would occur but we observed that because of the freezing temperature of the weather our cannons did not fire.
This is a very good observation! good job nicole! Your paragraph is very thorough adn has a good topic sentance!
