#### Transcript of Bottle Rocket

Blast Off ! by Stephanie Castro, Joana Arriaga, Elmer Cabrera, Josue Adan Step 2 I gathered my materials First I start by gathering all my materials. 2 bottles
1 shoe box
(or any hard material)
tape
scissors Step 2 Cut of one of the two bottles to create the cone of the rocket. I continue by cutting the
wins for the rocket. step 3 Step 4 I taped my fins to the bottle step 5 finally my rocket is complete. Design Bottle rocket
( Mickey Mouse ) First Step - The first step is to cover half of the bottle with red construction paper Third Step Step 1 step 2 cut one bottal to be used as a cone Step 3 glue the cone bottle on the
base bottal Step 4 tape both bottals
together step 5 cut the foam into
wings step 6 cut triangle shape this are support for the
wings step 7 glue the fins step 8 glue the supprot shapes
next to the wings step 9 paint your rocket Combined Gas Law The combined gas law is a gas law which combines Charles's law, Boyle's law,and Gay-Lussac's law. Charles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant. Boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature. Gay-Lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume. Distance Rocket Hang Time Rocket Accuracy Bottle Rocket Step 1 demonstration in relation to volume ,pressure , temperature and moles Purpose of demonstration and how it is important and relevant to our daily lives It is important to our daily lives because we always ask ourselves why does this happen? how does it happen? and lead to a deeper understanding AVOGADRO'S L AW Avogadro reasoned that one liter of any gas must contain the same number of particles as a liter of another gas, which he called particles. Avogadro suggested the use of a large quantity as a basic unit, since molecules themselves are very small. Avogadro's law describes the connection between gas volume and number of moles. The Ideal Gas Law This law involves the parameters of temperature, pressure, and volume, but it also introduces the number of moles.The ideal gas law can be stated as a formula, pV = nRT, where p stands for pressure, V for volume, n for number of moles, and T for temperature. There are five basic postulates to the kinetic theory of gases:
1. Gases consist of tiny molecular or atomic particles.
2. The proportion between the size of these particles and the distances between them is so small that the individual particles can be assumed to have negligible volume.
3. These particles experience continual random motion. When placed in a container, their collisions with the walls of the container constitute the pressure exerted by the gas.
4. The particles neither attract nor repel one another.
5. The average kinetic energy of the particles in a gas is directly related to absolute temperature. Kinetic Molecular Theory Step 2 I cut two pieces of cardboard Step 3 Then I taped the construction paper to the fins Step 5 I created a cone out of the blue construction paper and inserted clay at the tip of the cone I taped my two fins to the side of the bottle Step 4 Second Step - Second step will be to cover the other half of the bottle with black paper or paint the other half with black paint - Cut three wing shape cardboard
and six of of the same shape with yellow paper - Paste one of the yellow papers to each side of the cardboard
shaped wings Forth Step - Cut out two median size circles with black paper
-cut out to ovule out of white paper
-Cut out two large wings out of paper. Fifth Step - Paste all the parts to the bottle
the big white wings go at the middle of the bottle -The yellow small wings go around the bottom of the bottle Sixth Step Final Step Paste the ovule shapes at the middle of the red half

The black circles go at the top of the bottle to make the ears.
