Popular Science to motivate students INDEX:

1. Identification of a problematic situation. 2. The impact of this problem. 3. Analyzing the possible causes of it. 3.1 The negative view of science from society 4. Actions that are been developed to solve the problem. 4.1 Examples of concrete actions.

Boring Important # of secondary students perceive Science as a group of

Useless Dangerous Difficult

Low interest in Science in schools & high schools.

subjects.


Popular Science to motivate students 2. The impact of this problem Low interest in Science in schools & high schools.

The # of students in scientific university studies is decreasing

The # of new, young & autochthonous, scientists will decrease

Lack of communication between research world and the society

No discrimination, by society, between science & pseudoscience. Frauds

Negative view of Science by society

4


Popular Science to motivate students 3. Analyzing the possible causes of the problem Low interest in Science in schools & high schools. Why?

Due to the influence from society Why? -Ancient bad chemistry -Image of scientists in films -Lack of communication Research world – daily world

Due to a wrong science teaching way Scientific subjects -Perceived as difficult ones -Perceived as useless ones -Perceived as boring ones -Perceived as dangerous ones 5

B) Image of scientists in films:

Crazy or evil ones

Popular Science to motivate students 4. Actions that are been developed to solve the problem From University of Girona we are developing Popular Science tools

Chair of scientific culture and digital communication

To motivate secondary students to be enrolled in scientific university studies and become researchers

To improve the society in general, its critical sense, scientific culture and respect for the nature

8


Popular Science to motivate students 4. Actions that are been developed to solve the problem Popular science tools that we use: A: Publication of striking short videos about spectacular scientific processes

9


Popular Science to motivate students 4. Actions that are been developed to solve the problem B: Recreational physics and chemistry live We think that the best way to motivate secondary students in science is to Bring the most spectacular experiments and processes in their high-schools.

Popular Science to motivate students 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.

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.

Popular Science to motivate students Examples of concrete actions 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 ďƒ the red cabbage, a natural pH indicator.

Litmus paper, a lab pH indicator

Red cabbage, a daily natural pH indicator 20

Popular Science to motivate students Examples of concrete actions B) Preparation of an edible green fried egg and a red lemonade -Acid solution  color changes to red Red cabbage mixed with -Netral solution  color remains to purple -Basic solution  color changes to green or yellow (extreme)

21


Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade

1. Boil the red cabbage in water

22


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)

23


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)

24

4. Fry the egg.
