Two-Liter Bottle Rocket ProiectThe Project:Your task for this project is to design and construct a rocket out of two liter pop bottles. Thegoal is to construct a rocket that will fly the highest in the air and stay in the air the longest timepossible.Your rocket will be constructed using two liter bottles. You may add components to the bottle,but the base bottle must be standard sized, and unchanged. This bottle will hold the water andcompressed air that will be used to launch the rocket. Your rocket may include fins,parachutes, or other components you think will help it fly the best, as long as the rocketrequirements below are met.Calendar:

o lf rockets are submitted after the due date. 1.0 points from the overall project grade willbe deducted. lf they are not submitted by the last launch dav, the rocket will not belaunched, and no points for the launching can be obtained.o lf the evaluation report and materials are not submitted by the due date, five points willbe deducted for each dav thev are late.

Rocket Requirements:1. The pressurized area of the rocket must be constructed from a 2-liter pop bottle.2. The structure of the pressurized portion must not be changed. (Do not heat the bottle,

or try to change its shape)3. No metal parts can be used on the outside of the rocket.4. All energy from the rocket will come from the air and water.5. lf parts of the rocket are designed to separate during flight, they should remain

connected together during the entire flight. Time will stop when the first part of therocket touches the ground.6. Hot glues, super glues, and epoxies cannot be used to attach components of the rocketto the pressurized portion of the rocket. Regular school glue or tape can be used.

Name: Period:Procedure:1. Decide where to cut the cup to make your boat. Make sure your boat and your

partner's boats are different sizes.2. Find the volume of each boat by filling it with water and pouring the water into agraduated cylinder. Record the volume of your boat in milliliters (mL) on the data table.3. Decide how many weights to put in your boat. Each group can use 50 weights. Recordthe number of weights in the data table.4. Find the mass of your boat with the weights. Record the mass in the data table usinggrams (g)5. Place your boat in the water. Record if the boat sinks or floats.6. Calculate the density of your boat. Remember, denistl,' : ffi Show your work.

7. Record the density of your boat in the data table.8. lf your boat sank, try to decide what you can change to make your boat float. Writedown what you plan to change.

9. Place your boat in the water again and record what happens.L0. When finished, dry your table. Throw away your cup, return your weights, and answer

the questions on the back.Name:

Questions:1. Did the changes you made to your boat help it float? Why do you think they did or didnot?

2. lf your boat sank, is it more dense or less dense than water?3. Using what you observed about density, what can you infer has to be true for an object

to float in water?

4. Describe the effects of your changes on the density of your boat.
