2. U NDERSTANDING : The type of chemical reaction that occurred was in the beginning a double replacement and ended with a decomposition. Decomposition reaction would be breaking like breaking water down into oxygen and hydrogen. The chemical equation is NaHCO3(baking soda) + CH3COOH(vinegar) --> CH3COONa + H2CO3 (carbonic acid). At the end of the reaction the pressure builds up and that is what makes your rocket launch. What type and design is best for the rocket.

3. P LAN To plan you need to get the materials for your rocket: a plastic bottle, cardboard, scissors, tape, paint,stopper, baking soda, vinegar,measuring equipment and paper towels (and make a top if you want). You need to take into consideration of the weather of the day and the angle of your launching pad which is 45 degrees for us Keep in mind of the chemical reactions that will be occurring. ( Double replacement and decomposition)

4. H OW TO BUILD A ROCKET ( THE SIMPLE WAY ) Steps: 1) cut out your wings with the scissors you have. 2) Cut out a top piece for the top of your rocket. 3)Attach the wings and top to the plastic bottle. (Making sure its fully attached.)

5. S OLVE For solving you need to test your rocket. My first testing didn’t work at all. The stopper came out because it wasn’t in tight enough. My second testing my rocket went 5 ft. The ratio I used was 60 to 3 which is 20 to 1 multiplied by three. ( It worked out pretty good for simply launching it.)

6. L OOK B ACK Looking back, I could have improved My ratio (increasing my vinegar and baking soda amount) The structure of the rocket (I could have added a top to the rocket instead of just having it as the way it was.) 60:3  90:6?
