5. Mars Pathfinder
Mars Pathfinder entered the upper atmosphere of Mars at 7.6 kilometers per second at a 14.2 degree angle (90 degrees would be straight down). It met its peak atmospheric shock, encountering forces 25 times Earth's gravity, at 32 kilometers above the surface. At 10 kilometers above the ground, a parachute deployed at nearly twice the speed of sound (400 meters per second). Rockets inside the back shell fired to further slow the lander's descent. Shortly before landing, a set of airbags inflated to cushion the impact. After a few seconds, the tether attaching the lander to the backshell and parachute severed, and with 90 percent of the fuel expended, the rockets carried the shell and other debris away from the landing area. Then, protected by its airbags, Pathfinder bounced on the Martian surface, as high as a 10-story building, before finally coming to rest after its 8-month journey.

12. Independent variable: different type of wax
A shopping mall wanted to determine whether the more expensive “Tough Stuff” floor wax was better then the cheaper “Steel Seal” floor wax at protecting its floor tiles against scratches. One liter of each brand of floor wax was applied to each of 5 test sections of the main hall of the mall. The test sections were all the same size and were covered with the same kind of tiles. Five (5) other test sections received no wax. After 3 weeks, the number of scratches in each of the test sections was counted.
Independent variable: different type of wax
Dependent variable: # of scratches
Control: five sections with no wax
Constants: 3 weeks, one liter, same size, same floor

13. Independent variable: different type of wax
Jack wanted to test which brand of car wax was most effective. He tested four brands of wax. He cleaned the hood of his car and removed the old wax. He measured four equal sections on the hood of the car. Each of the waxes was used to cover a section. An equal amount of wax, the same type of rag, and equal buffing were used. Five drops of water were placed on each square, and the diameter of each drop was measured (cm) (quantitative). Jack could have used a qualitative dependent variable by developing a rating scale for amount of shine, from dull to very shiny.
Independent variable: different type of wax
Dependent variable: diameter of water drop
Control: no wax on car
Constants: equal wax, same rag, equal buffing

14. Independent variable: different age grass compost
After learning about recycling, members of John’s biology class investigated the effect of various recycled products on plant growth. John’s lab group compared the effect of different-aged grass compost on bean plants. Because composition is necessary for release of nutrients, the group hypothesized that older grass compost would produce taller bean plants. Three flats of bean plants (25 plants/flat) were grown for 5 days. The plants were then fertilized as follows: (a) Flat A: 450 g of 3-month-old compost, (b) Flat B: 450 g of 6 month-old compost, and (c) Flat C: 0 g compost. The plants received the same amount of sunlight and water each day. At the end of 30 days the group recorded the height of the plants (cm).
Independent variable: different age grass compost
Dependent variable: height of plant
Control: 0 compost
Constants: sunlight, water, 30 days, 450 g of compost
