Which of the following was a constant in both experiments?
F. Length of vertical stick exposed
G. Shadow direction
H. Day of the year
J. Shadow length
The experimental design description states that a stick of a given dimension was used to create shadows of various lengths.
The experimental description states that, in all cases, 1.0 meter of the stick was left above ground. This was constant in both experiments.
The experimental results show that shadow direction varied throughout both experiments.
The experiments were performed on six different days.
