Can you answer these questions? What are the four basic elements found in the human body? Can you name any minerals? What are they good for? Can like exist without water? What happens in the human body when there´s not enough calcium? Why is iron important in the human body? How are iodine and thyroid connected? What is an isotope? Who was John Dalton? What holds the atoms together? Can you comment the chemicals used in the production of: a) medicines b) metals c) transistors d) plastics e) textiles f) fertilizers 1T 2F 3T 4T 5F (potassium) 6T 7T 8F 9T Are these statements true of false? Nutrients in the human body perform various functions, including the building of bones and cell structures, regulating the body's pH, carrying charge, and driving chemical reactions. Magnesium is not a mineral. Oxygenand hydrogen are predominantly found in water. Calciumis the most common mineral in the human body. Calcium helps to regulate heartbeat. Fluorine prevents tooth decay. Zinc deficiency has been known to lead to dwarfism in developing countries. All atoms of a certain element do not contain the same number of protons. Does lithium belong to alkali metals? Can you comment these elements discovered during the last decades?

Discussion What are some qualities of gas? Where is nature is it found? How is gas created? Can gas be dangerous? Why? When? Where can we find gas in our everyday life? How is gas stored? Is gas flamable? What is the „Boyle´s law“ about? Do you know any other gas laws? What colour is gas? What is the „Ideal gas equation“? What is it good for and when is it used? What do you know about the motion of gas? What is the role of gases in the atmosphere? Can you comment these statements about the motion of gas? 1 The molecules in a gas are small and very far apart. Most of the volume which a gas occupies is empty space. 2 Gas molecules are in constant random motion. Just as many molecules are moving in one direction as in any other. 3 Molecules can collide with each other and with the walls of the container. Collisions with the walls account for the pressure of the gas. 4 When collisions occur, the molecules lose no kinetic energy; that is, the collisions are said to be perfectly elastic. The total kinetic energy of all the molecules remains constant unless there is some outside interference with the 5 The molecules exert no attractive or repulsive forces on one another except during the process of collision. Between collisions, they move in straight lines. Noble gases – can you coment these gases and say something about their use? HELIUM NEON ARGON KRYPTON XENON RADON

What do people have in common with it? • Can you comment these harmful pollutants that people produce? How are they made? What do they cause? Is it necessary to use them in industry? • Sulfur oxides (SOx) • Nitrogen oxides (NOx) • Carbon monoxide (CO) • Carbon dioxide (CO2) • Volatile organic compounds (VOCs) • Particulates • Free radicals • Metals • Chlorofluorocarbons (CFCs) • Ammonia (NH3) • Odors • Radioactive compounds • How does the hole in the ozon layer influence our lives? Are these statements true of false? Like solids and liquids, gas is a common state of matter. Pure gases are made up of just two atoms. Neon is an example of a pure gas. Compound gases contain a combination of different atoms. Carbon monoxide (CO) is an example of a compound gas. Gas pressure is measured in pascals. Noble gases are a group of chemical elements that are very stable under normal conditions. Naturally occurring noble gases include helium, neon, argon, krypton, xenon, radon and iron ore. The ozone layer that protects Earth from the Sun’s potentially damaging UV light is made up of ozone (O3). 1T 2F (one) 3T 4T 5F (not iron ore) 6T

Discussion What is thermochemistry about? What kinds of energy do you know? Where does the energy come from? What do we need to create energy? Where does human body get its energy? What is the difference between these kinds of energy: kinetic, thermal, potentialand chemical? What is a calorimenter used for? What is the difference between exothermic and endothermic reactions? The first law of thermodynamics states that energy cannot be created or destroyed, only transformed or transferred. How do you understand it? The second law of thermodynamics states that the entropy of the universe increases with every energy transfer or transformation. The universe is in a state of increasing entropy. How do you understand it? What is Hess´s law about? What sources of energy do we know? What is renewable energy? Why are people interested in it? Is renewable energy expensive? What is nuclear power? Why is nuclear power such a controversial issue? What can go wrong in a nuclear plant? What are fossil fuels? Do we have unlimited amount of them? Do you think it´s possible to use only solar energy for a car or a house? What are the energy sources of future?

Discussion Why do people use chemicals in wars? Who started using them? What kinds of chemical weapons and gases do you know? What are some symptoms of being under influence of a chemical weapon? Is there any protection against chemical weapons? Can you comment these words? POISONOUS INHALE BURN BLISTER DIE SPREAD LUNGS TROOP TRENCH BOMB ATTACK BLIND INJURE EXPLODE GAS MASK DROPLET TREATMENT CAUGH BLOOD SWEAT CHOKE Can you say something about these chemical weapons? SARIN TABUN PHOSGENE PEPPER SPRAY AGENT ORANGE NAPALM What do you know about....? the efford to reduce the amount of weapons in the world countries who want to develop new weapons about the materials needed for the development of weapons terrorism vs. weapons Czech weapons and army American and Russian armies and efford the conflict between the Southern and Northern Korea? the use of weapons during the WW1? the use of weapons during the WW2? the use of weapons during the war in Vietnam? using chemicals in concentration camps? the last war conflict and the weapons that were used? NATO and their control of the production of chemical weapons?
Can you comment these historical facts Tularemia , anthrax and botulism toxins were effectively weaponized during the government of Winston Churchill. Army did research on biological weapons. Fatal human experiments were often conducted. Bombs full of fleas carrying the bubonic plague were created. Many chemicals ruining livestock or crops were introduced. Modern use of chemical weapons dates back to World War I, when weaponised commercial chemicals such as chlorine, phosgene and mustard gas caused agonising suffering and tens of thousands of deaths. Between April 1997 and July 2013, the Organization for the Prohibition of Chemical Weapons - conducted more than 5,000 inspections in 86 countries. Seven state parties have declared chemical weapons stockpiles totalling over 70,000 tonnes, and so far some 80% of this has been destroyed . But only three countries - Albania, India and a third party widely believed to be South Korea - have destroyed all their stockpiles. The countries with the biggest declared stockpiles, the United States and Russia,failed to meet deadlines for their total destruction in April 2007 and April 2012. Five states - Angola, North Korea, Egypt, Somalia and Syria - have neither signed nor ratified the agreement of destroying their chemical weapons. Controversial usage of chemical weapons during wars and coflicts – can you comment them and express your opinion?
