    Popular Science to motivate students Popular Science to motivate students Presentation Transcript

    • Popular science and recreational chemistry as a way to bring science to secondary students Popular Science to motivate students Pep Anton Vieta, May 2010
    • INDEX:
      • Identification of a problematic situation.
      • The impact of this problem.
      • Analyzing the possible causes of it.
      • 3.1 The negative view of science from society
      • Actions that are been developed to solve the problem.
      • 4.1 Examples of concrete actions.
      Popular Science to motivate students
      • Identification of a problematic situation
      Important # of secondary students perceive Science as a group of Boring Useless Dangerous Difficult subjects . Low interest in Science in schools & high schools. Popular Science to motivate students
      • The impact of this problem
      Popular Science to motivate students 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. Low interest in Science in schools & high schools. Negative view of Science by society Frauds
      • Analyzing the possible causes of the problem
      Popular Science to motivate students Low interest in Science in schools & high schools. Why? Due to the influence from society Due to a wrong science teaching way Why? Scientific subjects
      • Ancient bad chemistry
      • Image of scientists in films
      • Lack of communication
      • Research world – daily world
      • Perceived as difficult ones
      • Perceived as useless ones
      • Perceived as boring ones
      • Perceived as dangerous ones
    • 3.1 The negative view of science from society Popular Science to motivate students A) Ancient bad chemistry : Due to: B) Image of scientists in films : Crazy or evil ones
    • 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
      • Actions that are been developed to solve the problem
      Popular Science to motivate students 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
    • Popular Science to motivate students
      • 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
    • Popular Science to motivate students B: Recreational physics and chemistry live
      • Actions that are been developed to solve the problem
      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. Bell-lloc. Girona, January 2010
    • 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.
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 1/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 2/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 3/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 4/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 5/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 6/7
    • Popular Science to motivate students A) Implosion of a metallic drum as a recreational physics process 7/7
    • 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.
    • 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
    • Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 4.1 Examples of concrete actions Red cabbage mixed with
      • Acid solution  color changes to red
      • Netral solution  color remains to purple
      • Basic solution  color changes to green or yellow (extreme)
    • Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 1. Boil the red cabbage in water
    • 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)
    • 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)
    • Popular Science to motivate students B) Preparation of an edible green fried egg and a red lemonade 4. Fry the egg.
    • 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)
