Inquiry – Information from labs done in class
In a class experiment, ice water measured at 0°C was poured into three jars. Each jar was the
same size and held 200 mL of ice water. Each jar was wrapped with a different color Styrofoam:
white, red or black. Each jar was placed in sunlight and the temperature of each was recorded
every 30 minutes. The data is in the table below:
Black Styrofoam
White Styrofoam
Red Styrofoam

41. What was the manipulated variable? ________________________________________
42. What was the responding variable? _________________________________________
43. What were two controlled variables? _________________________________________
_______________________________________________________________________
44. Label each of the following as an observation, inference, or neither.
__observation____ The white Styrofoam got to 11⁰C after 90 minutes.
__neither_________________ The red Styrofoam got to 26⁰C after 60 minutes.
__neither_________________ Making Styrofoam is bad for the environment.
______inference_____ The black Styrofoam got the warmest because it absorbed the most light.
