1. Helium & Air Footballs

2. Place these statements in order. I. Jaime believes that the helium filled football will travel farther than the air filled ball. II. Jaime discovers that the footballs all traveled about the same distance from the kicker. III. Jaime wants to find out if a football filled with helium will travel farther than a football filled with normal air. IV. Jaime does some research on the properties of helium, properties of the gases that make up air, & footballs. V. The results do not support his hypothesis VI. Jaime decides to test 20 footballs. He empties out all of the air in the footballs and finds their mass before filling them. He then fills 10 balls with the same amount of helium and 10 balls with the same amount of air. He then kicks each ball and measures how far they travel.
