INTRUCTIONS ON HOW TO USE IT: This Excel game is to be used as a sort of quiz game in Chemistry and Geology. The file contents two Excel sheets (bottom left of the screen), one for each subject. The user (student) will see several pictures related to these subjects, and in the box underneath he/she will write the word which describes the picture. If it is correct, it will be so announced with a green background. If not, it will be red and the user will be asked to try again.

“Let’s continue with the mysteries theme. I have some riddles for you.” The class is now divided into groups of 4-5 students, riddles are presented to the class one by one. Each group has to discuss the riddle in English and then the first group to find out what the answer is gets 1 point. If the riddle is too difficult for the students, the teacher gives hints. The winning group receives some present- something little, connected with the topic.

The students work with crimes in different ways. They look up words, learn them, discuss crimes in groups and class, they watch a short film, write an interrogation and a letter, they look up facts on the Internet. They then present their letter written and gives an oral presentation of the chosen criminal or crime.
Aim: Working with this activity the students will learn how to find information on the Internet, they will listen to English and they will use written and spoken English. They will learn new words.

Purpose: For the students to develop comprehension of the conception of osmosis and practice their skills to work scientifically by means of experiments

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