Scientific Method and Experimental Design

The video tutorial covers the scientific method, emphasizing safety in experiments. It explains the steps of the scientific method using a real-world example of a petting farm's website experiment. The video details how to set up an experiment, analyze results using graphs, and identify trends. It concludes with a summary and offers additional resources for further learning.

Why is it important to have an adult present during experiments?
