PREDICT everything you think this video is going to be about. Brain-dump - write as much as you POSSIBLY CAN! If you need to be pushed, set a 3 or 5 minute timer, and stare at this screen and think about the gimkit we played in sync.
Why are you doing this? It's how you build a foundation - you're clearing the ground and setting some bricks up in your brain so that this video can build on what you already know, so do not Google or look for other sources.
Hint words - Nature of science, scientific method...
