Chemistry involved in your life.

Chemistry: science that studies matter

• Matter is everything that take up space

Name at least 20 things in the classroom that are made of matter:1.-2.-3.-4.-5.-6.-7.-8.-9.-10.-

11.-12.-13.-14.-15.-16.-17.-18.-19.-20.-

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

Remember to answer in English

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. l

ie

Advertise and chemistry

• Look for 2 commercials that are involved with chemistry

• On your index card

1. Write your name

2. Write the title “Advertisement true or false”

3. Write your product name and what is for?

4. Explain why chemistry is involve in your product

5. Decide is it true or false Explain your answer

6. On the other side repeat steps 3 to 5 for another commercial you find intrested

Describing matter

• Complete the Venn diagram with the properties of water from a glacier and from a geyser.

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)

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

oAluminium canoCopper sheetingoBrick houseoGlass windowoSilver spoonoWood 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

1. Write your name

2. Write the title “Describing matter”

3. 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.
