We know all experiments start with:
asking a question "I wonder what would happen if.. ?
then making a prediction/guess
next conducting the experiment
then observing and recording the results
and finally understanding and explaining the science
Our first experiment is called "Runnaway Pepper."
Question:What would happen if we put a finger, with dishwashing liquid on it, into a bowl of water with pepper sprinkled on top?
Our class made several predictions including "our finger would get burnt", "the pepper would stick to our finger" and "the pepper would disappear."
Here's what actually happened
So why did this happen? Well, when dishwashing liquid mixes with water it weakens the surface tension of the water causing the water to move away and take the pepper along for the ride. It's as simple as that!
