Baccalauréat technologiqueÉpreuve d'enseignement technologique en langue vivante 1série STLRappel du règlement d'examenÉpreuve orale, évaluée en cours d'année.Seuls sont pris en compte pour l'examen du baccalauréat les points supérieurs à la moyenne de 10 sur 20. Ces points sont multipliés par deux.Objectifs de l'épreuveL'épreuve porte sur les compétences de communication en langue vivante 1 dans le contexte de la réalisation du projet en biotechnologies ou en sciences physiques et chimiques en laboratoire. Elle permet d'évaluer les capacités du candidat à présenter en langue vivante 1 les différentes problématiques scientifiques et techniques auxquelles il est confronté et à expliquer en langue vivante 1 les choix effectués. Sont notamment évalués le lexique fonctionnel utilisé ainsi que les compétences sociolinguistiques et pragmatiques mises en œuvre en vue d'une communication efficace.Structure de l'épreuveCette épreuve se déroule en deux parties. La première est conduite dans le cadre de la première partie de l'épreuve de projet, définie par la présente note de service. En revanche, l'organisation de la seconde partie est indépendante de l'épreuve de projet ; elle est ponctuelle et se tient au cours du troisième trimestre. - Présentation orale en langue vivante 1 de la conduite de projet Une fois dans l'année, les compétences de communication du candidat en langue vivante 1 sont évaluées dans le contexte de la conduite de projet. La conduite de projet elle-même fait l'objet de l'épreuve de projet définie par la présente note de service.Cette partie est notée sur 10 points.L'évaluation est individuelle.- Présentation orale en langue vivante 1 du projet Cette partie est notée sur 10 points.Elle est organisée par le chef d'établissement au cours du troisième trimestre.En vue de la présentation orale en langue vivante 1, le candidat élabore un dossier scientifique et technique, sous forme numérique, en langue vivante 1. Ce dossier comporte 1 à 5 pages, tableaux et graphiques inclus. Ce dossier est un support de présentation, il n'est pas évalué.La présentation débute par un exposé du candidat, qui dispose d'une durée maximale de 5 min. Elle est suivie d'un entretien en langue vivante 1 avec les examinateurs. L'ensemble de l'épreuve a une durée totale de 10 min.

Résumé du contenu de la ressource :
Cette séquence permet de préparer les élèves aux présentations orales propres à l’examen du baccalauréat STL.L’objectif est de savoir réaliser une présentation de manière autonome, pour une prise de parole de 5min. Cet exercice peut se révéler très complexe car il sollicite la prise de parole en continu de l’élève et devant un public qui plus est.Pour cela, on procède à une approche progressive des difficultés. Cette préparation par étapes et donc avec niveau de difficulté croissant permet de dédramatiser cette épreuve qui pourrait paraître difficile au premier abord.
Dans « Part 1 » de cette ressource, l’élève doit présenter un montage de chimie, biologie ou physique de manière très guidée : les phrases à utiliser sont réunies dans un tableau qui donne une structure à sa présentation.
Dans « Part 2 », des thèmes sont proposés ainsi que quelques lignes d’explication. Des phrases clés sont proposées et l’élève doit organiser lui même sa présentation en l’articulant grâce aux expressions données.
Dans « Part 3 », l’élève est bien plus indépendant. Il doit choisir son thème, faire ses recherches et éventuellement regrouper son travail sous forme de présentation PowerPoint. Pour cela, il doit s’appuyer sur les conseils promulgués ainsi que sur les expressions orales proposées dans « Part 2 ».
Pour chaque présentation, une grille d’évaluation (personnelle et des camarades de classe) est fournie. Son objectif est de guider les retours qui seront donnés systématiquement à l’oral en fin de présentation. Ceci permet alors aux élèves de cibler leurs faiblesses et mettre en avant leurs points forts.

PART 2 : PRESENTATION (LEVEL 2) 1. CHOOSING YOUR TOPIC
Among the themes presented below, choose one that you would like to present.
Topic 1:Source : http://en.wikipedia.org/wiki/atom
The atom is the smallest unit of an element that retains the chemical properties of that element. An atom has an electron cloud consisting of negatively charged electrons surrounding a dense nucleus. The nucleus contains positively charged protons and electrically neutral neutrons. In an element, the number of protons in the nucleus equals the number of electrons. The atom is electrically neutral.
Topic 2:Source : http://en.wikipedia.org/wiki/ammonia
Ammonia is a compound with the formula NH3. It is normally encountered as a gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to foodstuffs and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. In 2006, worldwide production was estimated at 146.5 M tonnes.
Topic 3:Source : http://en.wikipedia.org/wiki/esters
Esters are a class of organic compounds. (R-COO-R’)Volatile esters, particularly carboxylate esters, often have a pleasant smell and are found in perfumes, essential oils… Esters can be synthesized in a condensation reaction between an acid and an alcohol in a reaction known as esterification.
Topic 4:Source : http://en.wikipedia.org/wiki/distillation
Distillation is a method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. Distillation is a unit operation, or a physical separation process, and not a chemical reaction.Commercially, distillation has a number of uses. It is used to separate crude oil into more fractions for specific uses such as transport, power generation, and heating. Water is distilled to remove impurities, such as salt from seawater. Air is distilled to separate its components—notably oxygen,

nitrogen, and argon—for industrial use. Distillation of fermented solutions has been used since ancient times to produce distilled beverages with a higher alcohol content.
Topic 5:Source : http://en.wikipedia.org/wiki/redox
Redox reactions describes all chemical reactions in which atoms have their oxidation number changed. The term redox comes from the two concepts of reduction and oxidation. It can be explained in simple terms:Oxidation describes the loss of electrons by a molecule, atom or ionReduction describes the gain of electrons by a molecule, atom or ion
Topic 6:Source : http://en.wikipedia.org/wiki/aspirin
Aspirin, or acetylsalicylic acid (A.S.A.) is a drug, often used as an analgesic to relieve minor aches and pains, to reduce fever, and as an anti-inflammatory medication.Aspirin also has an "anti-clotting" effect and is used in long-term, low doses to prevent heart attacks, strokes and blood clot formation in people at high risk for developing blood clots. The main undesirable side effects of aspirin are gastrointestinal—ulcers and stomach bleeding—especially in higher doses.
Topic 7:Source : http://en.wikipedia.org/wiki/Wave
In physics, a wave is a disturbance or oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. They consist, instead, of oscillations or vibrations around almost fixed locations. Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave.
Topic 8:Source : http://en.wikipedia.org/wiki/DNA
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses). The DNA segments carrying this genetic information are called genes. Likewise, other DNA sequences have structural purpose s, or are involved in regulating the use of this genetic information. Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life.

PART 3 : PROFESSIONAL PRESENTATION (LEVEL 3) 1. CHOOSING YOUR TOPIC
Choose a topic that you like and deals with physics, biology or chemistry. Do the necessary research and construct your 5min presentation. Should you choose to use a piece of software such as PowerPoint, make 5 to 10 slides using the advice given below.
2. TIPS ON HOW TO GIVE A POWERPOINT PRESENTATION
Presentation Contents
A member of the audience should visualize your presentation like this:
Introduction Welcome Explanation of structure
Body Usually three main points
Conclusion Summing up
The Slides
Fonts: use large fonts. Use thick lines for graphs. Colors: use strongly contrasting colors and avoid dark backgrounds. Title: EVERY slide should have a title. Similarly every slide (except the title page) should have
a page number. Main Ideas: Your points should not be full sentences. They should be short and the number
of points per slide should be limited. No more than 5-8 lines of text per slide.
The Presentation
Watch your time. Count on 30s-1min per slide (not too short, and not too long) Don't read your slide. Restate the points in your own words and elaborate on them. Look convinced. Act convinced. Practice the presentation beforehand. This helps to see if the content is good. It helps to get
the timing right. It helps you to familiarize yourself with the presentation. Talk to the audience, not to the screen/floor/laptop/projector.
Other Tips
Prepare extra slides to answer expected questions. This is very helpful if the answer is complex and a slide can help clarify it.
