When the students were on the Dance Stage, they were easily able to follow all of the dance moves.
Later, when the students were about a mile away from the Dance Stage, they could still see the lights flash and hear the music, but the music was no longer timed with the light flashes, which made it difficult to dance in time with the lights and music!

Fun House
In the Fun House, there are all kinds of booths that feature tricks with lights. One of the favorites is “Light Detective”: trying to guess the color of a ball by shining different colored lights on it. The ball sits within a display case with a light control dial, that only allows one color of light to shine on the ball at a time. The table below shows the experimental results of shining different colored lights on the ball to determine its actual color.

Complete the sentence starters below to describe how light interacts with the ball:
A. The color that the ball appears to us depends on ___________________________________________________________________________________________________________
B. When a single color light shines on the ball, __________________________________________________________________________________________________________________
C. When white light shines on the ball, ____________________________________________________________________________________________________________________
Other Answer Choices:
the light wavelengths that it reflects towards our eyes; if it absorbs colors, the ball appears gray.
white light is composed of all colors so the actual colors of the ball could be seen (red with green stripes).
only the colors that the ball is made of will reflect; all the other colors will be absorbed and appear gray.
