Reaction velocity

  1. 1. Prague, 27 and 28th August 2011Carlos Cunha, E. Sec. Dom Manuel Martins, Setúbal, Portugal
  2. 2. Summer School, Prague, 2011
  3. 3. Good Practice description • Name: Reaction Velocity • Subject Area: Chemistry • Age of Students: 13-15 • Topic: Chemical Reactions • Content involved: Chemical reactions velocity • Skills (student skills) involved: Observation, Laboratory/Hand´s-on, autonomy, solving problems, interpretation, math & computer use. • Aims: – Help students understand a chemical reaction evolution; – Determination of the reaction velocity from the mass versus time graphic. • Duration: 2 x 90 minutesSummer School, Prague, 2011
  4. 4. Methodological aspects (1/2) • How to launch activities and raise student’s interest Activity begins with the movie presentation: http://www.youtube.com/watch?v=7VeGnJmIjxs http://www.youtube.com/watch?v=KI1BJL3bg1M The experiment will use current materials and reagents like ”vinegar” and ”backimg powder”; Does the concentration influence reaction velocity •How to organize students (individual work, pairs, larger groups, different ways at different moments … ) Large group for movie presentation and discussion; Working in pairs to prepare the experiment apparatus; Working in pairs to make the graph mass vs time; Final discussion in large group.Summer School, Prague, 2011
  5. 5. Methodological aspects (2/2) Resources needed (equipment, software, manipulative, text, video, websites, …) Vinegar; Backing powder; Two small PET bottle; Graph paper; Scale (it can be a kitchen scale); Computer with Excel (not mandatory). Specific strategies to keep students engaged Students will be asked to be involved in all activities, either by seeing movies and demonstrations, or by constructing their material and do their own measurements.Summer School, Prague, 2011
  6. 6. Detailed description of how to proceed • A detailed description of how to proceed: sequence of tasks in a chronological order including indication of time spent on each task – Theme presentation using a YouTube movie (aprox. 5 min); – Discussion about scale and how to make registrations (aprox. 15 min); – Experiment preparation (aprox. 15 min.); – Record the mass evolution during reaction, using a cell phone (aprox. 20 min.); – Play the movie, frame by frame and make the time versus mass table (aprox. 20 min); • A detailed description of how to proceed: sequence of tasks in a chronological order including indication of time spent on each task – Construction of a graphic on graph paper, using mass vs time (aprox. 40 min.); – Repeat procedure with another reagents concentration (aprox. 20 min.); – Replication of the activity using spreadsheet application (aprox. 30 min.).Summer School, Prague, 2011
