To do this, the scientist sedates and tags all of the lions within a pride. then, he places several remotely-controlled video cameras near the lions' den and performs an observational field study. he collects continuous video footage over the span of one year, analyzes the video, and then forms conclusions based on his observations. this example shows that

not all scientific knowledge is gained through controlled laboratory experiments.

Explanation:

Scientific knowledge is the information and knowledge that starts from the principle of analysis of real and scientifically proven facts. To be recognized as scientific knowledge, it must be based on observations and experimentation, which serve to attest to the truth or falsity of a given theory. This theory must be proved by experimentation, however, it does not matter if the experiment was done in a controlled environment like a laboratory, or in a totally unpredictable environment like a forest, the important thing is that the researcher can give concrete answers that answer hypotheses. and provide theories.

The scientist exposed in the above question did research with lions in a totally unpredictable environment and got clear answers to the hypotheses of his study. This is a perfect example that not all scientific knowledge is gained through controlled laboratory experiments.
