Educational experiences and practical works

Chemical analysis of various components of the Coca-Cola

Jordi Banús, Òscar Núñez i Irene Miquel

In this research simple analytical techniques have enabled us to find the concentration of various components of the Coca-Cola. Using density measurements has been determined the sugar content, through an acid-base titration was found phosphoric acid concentration and the concentration of caffeine was determined by the method of liquid-liquid extraction.

Keywords: coca-cola, chemical analysis, density, sugar, acid-base liquid-liquid extraction
 

Building a line follower vehicle

Roman Gutiérrez

It is designed and builded a non-programmable line follower vehicle, capable of detecting a black line painted on the floor and follow it autonomously. This is a work that can be done both in 4th year ESO or Batxillerat dependig of the degree of complexity of the design that we decide (if it is programmable or not ...)

Keywords: technology, vehicle line follower, Electronics
 

Diagnosis of educational provision for school-related
with the natural environment in environmental education centers

Concepció Rodon

The results of the research describing the characteristics of environmental education centers working the coastal-marine in Catalonia and the range of activities aimed at high school. Working in situ from science centers and activities made environment makes learning more relevant, reflective, participatory and dynamic.

Keywords: environmental education, high school, middle-shore marine resources
 

Educational experiences: CLIL

Rethinking, rewriting, rewriting or learning
to teach science through English

Roser Canet

It presents the reflections on science education generated from reviews CLIL materials (natural sciences in English) for 1st ESO, performed at the UAB during the tutorials with Dra. Cristina Escobar, Teaching of Language, and Dra. Neus Sanmartí of Science Teaching. The materials have been tested at the Institute Montserrat with a group of 30 students through the Foreign Language Experimental Plan issued by the Department of Education.

Keywords: CLIL science education, previous ideas, evidence, arguments, values
 

Designing a teaching sequence of chemical activities
ESO for a contextualized in the kitchen
with CLIL methodology: "Chemistry in the kitchen"

Lorena Payà

It presents the teaching sequence of activities developed during a license of type C in 2007-2008. This sequence corresponds to the chemistry part of the curriculum in the sciences of the nature of an ESO under the title "Chemistry in the Kitchen." The nexus of teaching units is the kitchen. The sequence is ready to be taught in English using a methodology CLIL (Content and Language Integrated Learning).

Keywords: chemistry, kitchen, CLIL, 1st ESO

 

Reflections and researches on science education

The conversation and peer interaction:
two classroom experiences

Teresa Calveras, Montse Padern i Rosa Maria Tarin

It includes extracts from two teaching experiences undertaken during the academic year 2008-2009 in the stages of childhood and primary education. These experiences have been designed and prepared as a group, experienced and subsequently revised. The article focuses on aspects of peer interaction and the classroom organization and management enhanced by this interaction.

Keywords: model of living, speaking, classroom management, cooperative work, peer interaction
 

Competential analysis of the teaching unit "I feel good?"

Eulàlia Puig, Ana Castillón i Rosa Maria Tarin

It contrasts a teaching unit for primary school pupils with competence richness criteria of CESIRE-CDEC.

Keywords: criteria of richness competence, teaching unit, science, curriculum, modeling
 

Deeping in the science
