What is the difference between experiment and experimentation?

If I am correct, both experiment and experimentation exist in English. Which one should I use? Can I say the following two sentences?

• This week, I am conducting new experiments at the laboratory
• This week, I am conducting new experimentations at the laboratory

If the answer is yes, is there any difference between them?

Solution 1:

Experimentation is the act of doing experiments.

So you would say "I am conducting new experiments at the laboratory"

eg. "not all experimentation is done in a laboratory" means sometimes experiments are done outside the lab.

Solution 2:

Yes there is a difference.

Experiment is a test

Experimentation is the act of carrying out a test, or doing tests.

E.g.:

Over 200 experiments are carried out each week at the laboratory.
The new car is undergoing experimentation by the expert drivers at the race track.
