Intrested areas for studying chemistry Health: wellbeing (medicines, hygiene products, menus, food conservation) Environment: All matter is taken from here ( soil, air, water) Use for your benefit but also for wrong purpose

Tv and magazines infomercials and advertisements Infomercial: a television program that promote products in an informative and supposedly objective way. Advertise: describe or draw attention to a product, service or event in a public medium in order to promote sales or attendances True vs. lie

Advertise and chemistry Look for 2 commercials that are involved with chemistry On your index card Write your name Write the title “Advertisement true or false” Write your product name and what is for? Explain why chemistry is involve in your product Decide is it true or false Explain your answer On the other side repeat steps 3 to 5 for another commercial you find intrested

Water Describing matter Complete the Venn diagram with the properties of water from a glacier and from a geyser. Water Matter: anything that has mass and take up space. Chemistry: science that studies matter and how matter changes. Substance: a single kind of matter that is pure. (salt and water)

Summarized How matter and substance related: ________________________________________________ ________________________________________________ ________________________________________________

Physical and Chemical properties of matter Physical properties: Characteristic of a substance that can be observed with out changing it into another substance ________________________________________________ ________________________________________________ Chemical properties: Characteristic of a substance that describe the ability to change into different substance

Basketball hoop Two physical properties of metal are luster, or shine, and the ability to conduct electric current and heat. Another physical property is flexibility (ability to be bend into shapes). Mark the objects that are flexible Aluminium can Copper sheeting Brick house Glass window Silver spoon Wood drumstick What do all the flexible objects have in common? __________________________________________ What physical property makes netal pots good for cooking?

Physical and chemical properties PP: water freezes at 0 ºC. Liquid change to ice but still water. “SAME SUBSTANCE” Boil and melt are physical properties ChP: Iron combine with oxygen of the air and for a “NEW SUBSTANCE” Rust, Tarnish, bubbling, getting hot or cold, explode, rotten, etc..

Physical and chemical properties Frozen fruit bar: Harden temperature, texture and color are physical properties. Solid, liquid or gas are called State of matter and are also physical properties Describe three properties of a frozen fruit bar, including its state of matter __________________________________________________________________________________________ Will any of these properties change after a couple of hours in the sun? Explain. ____________________________________________________________

Physical and chemical properties Charcoal briquettes: Fuel, like charcoal, can catch fire and burn. When a fuel burns, it combines with oxygen in the air and changes into the substance water and carbon dioxide. The ability to burn or flamamability, is a chemical property. How do you know that flamability is a chemical property? __________________________________________________________________________________________

Apply it! The wax in a burning candle can be describe by both physical and chemical properties 1: Describe the physical properties of the wax in a burnning candle. __________________________________________________________________________________________ 2: Why is melting a physical property of the wax, but flammability is a chemical property?

Index card work 2 Write your name Write the title “Describing matter” Answer the following questios: The melting point of table salt is 801 ºC. Is this a physical or chemical property? Helium does not usually react with other substance. Does this mean that helium has no chemical properties? Explain.
