7. Popular Science to motivate students 3.1 The negative view of science from society Due to: C) Lack of communication between research world and daily world Can cause No discrimination between science & pseudoscience by society Can cause Frauds or medical/psychological diseases

11. Popular Science to motivate students 4.1 Examples of concrete actions A) Implosion of a metallic drum as a recreational physics process With this experiment we are going to play with pressure creating a partial vacuum inside of a empty dissolvent metallic drum to achieve the implosion of it. This is a very visual and funny way to learn about pressures, atmospheric pressure, properties of gases and change of phases process.

19. Popular Science to motivate students 4.1 Examples of concrete actions B) Preparation of an edible green fried egg and a red lemonade With this experiment we are going to play with acid and base products that we have at our kitchen and a natural pH indicator o obtain a green fried egg and a red lemonade. This is a very visual and funny way to learn about pH indicators and acid-base chemistry.
20. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade We begin the experiment talking about the difference between acids and bases , and the way to distinct it in the lab. We present too different acidic and basic daily products like a lemon or an egg and the way to discover its acidity the red cabbage, a natural pH indicator . Litmus paper, a lab pH indicator Red cabbage, a daily natural pH indicator 4.1 Examples of concrete actions

22. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 1. Boil the red cabbage in water
23. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 2. Save the extraction (purple because water is neutral)
24. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 3. Mix the extract with the egg white (green because egg white is basic)
25. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 4. Fry the egg.
26. Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 5. We obtain a green edible fried egg (green because egg white is basic)
