Step 3:
Here are some videos from Forman´s best known movies. The students should focus on 2 points of Forman´s work:

An acidic solution is any aqueous solution which has a pH< 7.0 ([H+] > 1.0 x 10-7 M). A basic solution is an aqueous solution containing more OH-ions than H+ions. An aqueous solution with a pH greater than 7.

This is a grammar and vocabulary review activity (it is related to the world of art)
This is the way it works:
The teacher asks some questions so that students use known grammar in their answers (some will be more difficult than others).
Every time a student answers a question correctly they can click once on a slide to uncover part of a piece of art (or twice if the question is difficult). This will continue until a student guesses they type of art represented (portrait, sketch, etc.)
At the end of the activity the teacher and the students will do an assessment of the results.

Blubbr es una herramienta 2.0 que permite crear cuestionarios sobre vídeos, cada pregunta requiere un fragmento de vídeo diferente. Puede resultar muy útil para trabajar cualquier tema de forma audiovisual: música, reportajes de naturaleza, idiomas, diapositivas de arte, etc. La herramienta es sencilla y el resultado visualmente atractivo, hay que tener en cuenta que primero se visualiza el fragmento de vídeo y después aparecen las preguntas lo cual hace que los alumnos tengan que estar muy concentrados.
