5. Shawn is planning a scientific experiment
Shawn is planning a scientific experiment. He wants to learn whether the time of day has an affect on how far the rose petals in his mother’s rose garden open. He plans to measure the diameter of each flower every hour during a sunny day in the spring.
What is the independent variable in Shawn’s experiment?
a. the time of day
b. the number of flowers
c. the diameter of the flowers
d. the time of year

6. The timed performance of the three athletic events was the...?
6. In testing the effectiveness of an energy drink on the performance of athletes, 50 athletes were given water and 50 athletes were given a new energy drink called “Power Up.” After drinking one can of “Power Up”, each athlete was timed while performing a 30 meter sprint, 50-sit-ups, and 20 pull-ups.
The timed performance of the three athletic events was the...?
a. conclusion of this experiment
b. hypothesis for this scenario
c. responding variable (dependent variable)
d. manipulated variable (independent variable)

7. 7. Nick and Doug designed an experiment to find out if goldfish grow larger if fewer fish live in the same bowl. They measured the lengths of seven goldfish and placed them in identical bowls. Two goldfish were placed in one bowl, and the remaining five goldfish were placed in a second bowl (see below). .
For three months they poured the same amount of food into each bowl each day, and they maintained the water conditions the same. Then they measured the lengths of all the fish and compared them.
What is the responding variable (dependent variable) in this investigation?
a. length of the fish
b. number of fish per bowl
c. amount of food per fish
d. condition of the water

17. Write the correct abbreviation for each metric unit.
1) Kilogram __Kg___ 5) Millimeter __mm___
2) Meter ___m__ ) Liter __L___
3) Gram __g___ ) Kilometer __Km___
4) Milliliter __mL___ 8) Centimeter ___cm__
9) Milligram __mg__
Try these conversions, using the ladder method.
10) 2000 mg = 2 g ) 198 g = .198 kg
11) 104 km = m 17) 75 mL = .075 L
12) 480 cm = 4.8 m ) 50 cm = .5 m
13) 5.6 kg = 5600 g ) 5.6 m = 560 cm
14) 8 mm = .8 cm ) 16 cm = 160 mm
15) 5 L = 5000 mL ) 2500 m = 2.5 Km
22) 65 g = mg
23) 6.3 cm = 63 mm
24) 120 mg = .12 g
Compare using <, >, or =
25) 63cm < 6 m ) 43mg < 5g
26) 536cm = 53.6dm ) 1,500mL= 1.5L
27) 5g > 508 mg ) 3.6m > 36cm
