Experiment Scenario: Amelia loves to play golf but hates it when her golf balls go into the water. Some brands seem to soak up so much water that they never quite make it to the green
again. She has decided to test her dad's three favorite brands of golf balls to see which brand holds
the most water and would hinder her game.
Questions: The fact that she is going to use the same kind and amount of water to submerge each
ball is an example of a
variable. The weight of each ball after soaking in water
for ten minutes is an example of the
variable. The three different brands of golf
ball she will use is an example of the
variable.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
