The scientific practice that Rhonda is performing could be described as a scientific method in which she follows steps in order to conclude or analyze the results that she wants to find out or the experiment that she has been doing. This involves the observation in which she watches the video and could lead into the next steps such as hypothesis, experimentation, reports and conclusion that could lead her into solving how the reaction had happened.

Explanation:
Their is no data provided for the mass and length of pendulum in the picture.but it is very easy to check kinetic energy.KE is mv^2/2, m is the pendulum Bob and v is time dependent ,equation of displacement of SHM is given as x(t)=Asin(wt+∆) where ∆ is the phase angle now v=dX/dt _v=Awcos(wt+∆) and KE=
Thus w angular frequency of oscillation is√(g/l)
g acceleration due to gravity and l length of pendulum.so KE is same for pendulum having same mass and length otherwise KE expression with time will vary for all other cases.now check if all experiment pendulum have same mass and length otherwise KE will not be same.You can now easily verify.
