Background Information Advanced Excel/Exercise 2 3,2,1 Pop A rocket is a closed chamber with a gas under pressure. When the pressurized gas is allowed to escape, the rocket moves. Isaac Newton s Third Law of Motion states: for every action there is an equal and opposite reaction. The released gas is the action and the reaction is the rocket moving forward. In this activity, a gas is created and is kept under pressure in a film canister. The gas in a rocket can be produced chemically. Effervescent cold tablets, like Alka-Seltzer, contain baking soda and citric acid. When you add water to the tablet, a chemical reaction takes place between the baking soda and the citric acid. Carbon dioxide gas is produced and pressure builds inside the film canister. Finally, the pressure is so great it rushes out of the canister. The canister and paper rocket lifts off in the opposite direction. What can make a rocket fly higher depends on a number of variables: the weight of the rocket, the temperature of the water, the amount of tablet put in the canister, the number of fins and shape of the rocket, and the amount of water in the canister. In this activity, you will vary the amount of water to see which amount makes the rocket fly higher. Using Excel, you will calculate the average, maximum, minimum, and range of the rockets flown. You will use formulas for getting your answer. A formula is a set of instructions for making a calculation. In Excel, all formulas begin with the = sign. In this investigation, you will create one spreadsheet and graph. Hypothesis (How many meters do you think your rocket will fly?) Materials ½ effervescent tablet Translucent film canister Paper rocket Graduated cylinder Water Procedures 1. Build a rocket. 2. Cut effervescent tablet in half. 3. Measure out 15 ml of water with the graduated cylinder. 4. Pour the water into the film canister. 3,2,1 Pop Page 1
5. Working with a partner, put the tablet into the canister; cap the canister, and turn the rocket over onto the launch pad. 6. The class will record how high each rocket flies. 7. Repeat the prior steps with 20 ml of water. 8. Complete an Excel spreadsheet to calculate the average, maximum, and minimum height each rocket flew. 9. Complete an Excel chart to display results of the experiment. 10. Add your conclusions to your chart. Open an Existing Excel File 1. Start Microsoft Excel 2000. 2.
