5) Why is it technically incorrect to DRAW the galades on the balloon directly? 3) If you had picked another galaxy to be your "home galaxy would your results be different? Galaxy Measurement 1 Measurement 2 Difference Unit linch cm linchi rm inch Seconds H-DA H-> H->C H-D H-SE Circle the units you chose to use in the column titles Ranking Instructions: Rank from fastest to slowest the galaxies speed. Fill in with A, B, C, D, & E. Ranking Order: Fastest 1 Slowest The galaxies are all traveling at the same speed: (indicate with check mark). Information is insufficient to rank stages: (indicate with check mark). Carefully explain your reasoning for ranking this way: Answer these Questions: 1) Is there a "center" to your expanding universe? Why or why not? 2) Are the galaxies moving toward or away from each other? Why or why not? Why or not? 4) If the balloon itself represents space, what's really moving? Expansion of Universe Names Description For the lab you will use a balloon and some stickers to the expanding Universe Tools: balloon, galaxiestape, pen/pencil, peper ruler READ BEFORE STARTINGI Getting a friend to help might make this a little easier. 1) Start by placing alx galaxdes all over the donated balloon - try to remove the powder before affixing the galaxy. Experience has shown that you get the best results if some galaxies are close together while others are farther apart. Avold the neck of the balloon or the point opposite the neck, but otherwise, put your galaxies where you like. 2) Pick one of the galaxies to be your "home galaxy and label it with an H. 3) Label each of the other galaxies, lettering them A, B, C, D. & E. 4) Inflate the balloon to about the size of your fist. Do NOT tle it off Use the ruler to measure the distance in inches or centimeters from your home galaxy to galaxy 'A'. Ful in this data under the "Measurement 1 column in the chart provided. Circle the unit of your measurement (em or Inch) in the table and stick to that unit. Repeat the procedure for the other five galaxy pairs (home galaxy and galaxies B-E) with the balloon at this size. 5) Blow up the balloon up to at least double it's size AND record how long you took to blow it up. Record the time in the Time Between column for all five galaxy pairs. Repeat the measurements from your home galaxy to the other six galaxies and record your answers under the "Measurement 2 column. 6) Finally, subtract the Second Measurement from the First Measurement for the "Difference and divide that by the Time Between to get the "Speed" of the expansion (soo Equation), Record that value in the table for each galaxy pair. Circle the resulting units in the table (cm/s or Inches/s) Equation: Speed (in cm/ or inchen/s) (Measurement 2- Measurement 1)/ Time Between Complete the other side.
