Make sure you know the theory of the experiment you want to perform: print and read the pertaining articles, show them to your parents and explain
them what you want to do. Exagerate by going into details, write chemical equations, mechanisms, and explain them the experimental procedure. Try to
insist they listen to you.
Before you perform any experiment, make a thorough risk assessment together with your parents. Make sure they take this seriously and evaluate every
imaginable detail, every possible parameter, every hypothetical failure mode, everything. Chose the protection measures together.
Force them to supervise you during the experiments. Make them pay attention to every possible detail, especially if everything is performed in
accordance to the risk assessment decisions. Then make them be present when you report the experimental in your lab notebook. Ask them, if they
noticed anything you might have missed, so that you include their valuable comment in the notebook.
Explain them you insist on all this only because you feel they do not trust you and want them understand your passion.
Believe me, sooner or later you will annoy them so much that they will trust you know exactly what you are doing and they will leave you alone. If
they are truly as ideologically biased as you described them, annoying them to death is the best way to getting them to trust you and leave you alone.
Arguments usually don't beat the ideological beliefs as efficiently as brute force.
As a side product, you will also learn to reflect better on what you are doing and do it more safely. |
