Helium & Air Helium & Air FootballsFootballs

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 hypothesisVI. 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.

What type of data was taken in this experiment?

Exploding Pants

I. Adam tests 5 pairs of overalls. One pair is left alone. The 2nd pair is coated in the special fertilizer. The 3rd pair is coated in Ammonia. The 4th pair is coated in Gun Powder. The 5th pair is coated in Orange Juice. The overalls are placed on a flat surface & struck with a sledge hammer. Adam notes what happens to the overall when struck by the hammer.

II. Adam does some research on topics concerning the problem.

III. Adam’s data supports his hypothesis. IV. Adam believes that a special fertilizer will explode

when hit with a hammer. V. Adam records his observations in a journal.VI. Adam wants to find out if a pair of overalls will

explode if coated with certain chemicals and hit with a hammer.
