Length of the lessons: 3X 50 minutes

Number of pupils involved : 25 Age of the pupils : 16-17 years old

Purpose: Defining career interests of students

Opinion Poll Identify on a sheet of paper what job you want you to orientate and if you know how to recognize your strengths and weaknesses.

Establish areas of

interest

The teacher presents students' fields in relation to the types of jobs that these areas they cover.

I told the students about the most important 3-5 activities in that I was involved in last 6 months and I have created a special satisfaction.

I asked students to write on a sheet of paper three activities of they enjoyed doing in the last six months and then appoint professions that include these activities.

SURVEY OF SELF-KNOWLEDGE

Practical experience. Purpose: Accumulating of work experience to

achieve a career. I asked students to form groups of 5 and realize a

plan of make a career of their choice. I conducted a lesson visit in the local

slaughterhouse where they visited all the departments - from unloading containers with until chickens to their packing items.

Students understood wich are the personal skills they have gained from the experience.

The students had to complete a feedback form

50 minutes The Connection with science! Subject area : Chemistry Age of the students : 16 to 17 years old Content involved : Obtaining an red cabbage indicator Determination of starch in food

I presented some experiments conducted by other students .

EXPERIMENT - Method of direct exploration of reality used in teaching chemistry, biology, physics, technical sciences, consisting of an observation provoked and directed about hypotheses to be verified experimentally.

The OBJECTIVES of laboratory experiments > Fixing and enhancing knowledge previously acquired by

students; Acquisition new knowledge based on their own

observations; Forming of abilities of handling of tools, equipment and

materials laboratory.

The factors conditioning laboratory experiments

Choosing a some form of experiment is

conditioned by several factors:

- The existence of equipment and materials required for the experiment,

- Which is intended to be realized by the experiment in lesson

- Individual characteristics and age of the students,

- Interest to investigate the physical and chemical phenomena,

desire of collaboration with the students..

The integrating of laboratory experiment in lesson

As a teaching method, laboratory the experiments can be used in any

type of lesson and can be included in any stage of the lesson: To check knowledge; To capture attention; To transmit new knowledge; To strengthen knowledge; To assess knowledge

¼ From a red cabbage cut into small pieces and placed in a beaker to boiling for 15 minutes

Natural litmus

Way of working

https://docs.google.com/file/d/0B0RnsyEDg0PSazMyZ01wR2EyVXc/edit?usp=sharing

After it has cooled down, filtered through a paper filter and the rinsing liquid is put into the dropping bottle.

This is the natural litmus and it can refrigerate several days.

Can be used as a "litmus" and other indicators derived from flowers or tea

For the experiments can be use that natural litmus and :

c. liquid soap

b. lime juice

a. vinegar

d. sprite

e. Baking powder

f. Triumph cleaning solution

Determination of starch in food

Mode of work: In one slice of bread by means of a pipette a few drops were added to a solution of iodine in potassium iodide. Conclusion: Slice of bread has become a purplish-blue color due to the presence of starch. The blue color is

given by the pink amylose and amylopectin. On heating, color turns from blue in pink.

When adding iodine solution,

the rice and pasta were stained

in blue, showing the presence of

starch.

In the process of studying chemistry , students' knowledge acquired at various school subjects are integrated under different aspects, taking into account the principle interdisciplinarity.

The students find it difficult integrate the

individual knowledge gained from several disciplines of study, in order to form a holistic view on the objects, phenomena and processes examined.

The use of linkages interdisciplinary

Science-Technology-Engineering-Mathematics makes it possible to understand the essence of the scientific conception of the world, that it’s full charging and the causes of the various connections existing in nature, the study of new material based on the already known, enriching and enhancing it.

The interdisciplinarity of the experiment of

In CONCLUSION….

Motto: There are no great things, no little things.

There is something else. Anything else mean

what I like and what I do. ”

(Jacque Prevert)

Within the limits imposed by existing reserves, in its own pace,

based on the belief that everything has a beginning, to try to make ourselves

what we expect from others.

Questionnaire for determining feedback

To achieve the work load I suggest you see the this video for documentation. http://chemistryallaboutyou.eun.org/ Creating a documentary movie about the use of new technologies in science and technology for the achievement of analysis on food additives from food.
