1 Tuesday 9/9/14 Please take out your lab book Pencil Colored pencils Scissors Glue stick or tape Cartoon Tuesday Warm up: Draw a cartoon on Page 41 about something that takes up space and has mass (something that is matter!)

2 Composition of Matter WRITE THIS QUESTION ON THE TOP OF PAGE 44 WHAT S THE DIFFERENCE BETWEEN SUBSTANCES AND MIXTURES?

3 Matter Anything that has mass and volume Examples: A brick has mass and takes up space A desk has mass and takes up space A pencil has mass and takes up space Air has mass and takes up space

4 Substances Substance: type of matter with a fixed composition that cannot be separated by physical means. Elements Substance made up of atoms with the same identity Compound Atoms of two or more elements combined Examples: water (H2O) Carbon Dioxide (CO2)

Examples: Pizza, fruit salad, granite Homogeneous mixture in which two or more substances are

5 Mixtures Mixture: Material made up of two or more substances that can be separated by physical means Heterogeneous mixture in which different materials can be easily distinguished. Examples: Pizza, fruit salad, granite Homogeneous mixture in which two or more substances are uniformly spread out. Examples: vinegar, salt water, coffee Notice the uniform appearance Salt Water

6 Concept Map Cut out the terms from the first page in your packet. On the top of page 43, write: Answer: Mixtures can be separated by physical means whereas substances cannot. You will glue the terms on page 43 and draw a picture of your choosing to represent each type of substance and mixture.

8 Friday 9/12/14 Please take out your lab book Scissors Glue stick or tape Pencil Warm Up: On page 45 of your lab book write down this fun fact about matter! Liquids, solids and gases are the most common 3 states of matter on Earth, however, much of the matter of universe is in the form of hot plasma

Solution: Homogeneous mixture of particles so small that they cannot even

9 Types of Mixtures Page 46 Question: How can you determine which type of mixture something is? Solution: Homogeneous mixture of particles so small that they cannot even be seen with a microscope and will never settle to the bottom of their container. Examples: Vinegar, Soda (unopened), Hydrogen Peroxide

Types of Mixtures Colloid: type of mixture with particles that

out. Example: Milk (Water and Fat), Fog (water and air), Cool

of light at a colloid will make the light scatter this scattering

10 Types of Mixtures Colloid: type of mixture with particles that are larger than those in solution but still too light to settle out. Example: Milk (Water and Fat), Fog (water and air), Cool Whip *Detecting colloids is sometimes difficult so shining a beam of light at a colloid will make the light scatter this scattering of light by a colloid is called The Tyndall Effect. Tyndall Effect Fog

11 Types of Mixtures Suspension: heterogeneous mixture containing a liquid in which visible particles settle. Example: Italian dressing, muddy pond water, chocolate milk *Hint If it needs shaking to mix, then it s a suspension Italian Dressing Muddy water Chocolate milk

12 Poppy s Grocery Mart - 47 On page 47 in your lab book, glue in the Poppy s Grocery Mart Page. Cut out the different types of matter and glue them into the correct column Solutions, Colloids or Suspensions. There are 4 products in each column.

13 What kind of mixture? IN YOUR LAB BOOK ON PAGE 48, DRAW THE PICTURE AND TELL ME WHAT KIND OF MIXTURE IT IS AND IF IT S HOMOGENEOUS OR HETEROGENEOUS.

14 What kind of mixture? 1 Homogeneous or Heterogeneous? What kind of mixture? 2 3

15 4 Homogeneous or Heterogeneous? What kind of mixture? 5 6 7

16 Homogeneous or Heterogeneous? 8 9 What kind of mixture? 10 11

17 Tuesday 9/23/14 Please take out your lab book Pencil Highlighter Warm Up: In your lab book on page, draw a cartoon about a type/types of mixtures.

18 Combining Atoms There are over one hundred different types of atoms and they often times combine to make new substances known as molecules and compounds Molecule Results from the bonding of two or more atoms Compound A substance that contains two or more different elements (atoms) Example Oxygen Gas (O 2 ) Example Water (H 2 O) Compounds are molecules but not all molecules are compounds

19 Molecule or Compound

20 What is it? A GAME OF COMPOUNDS AND MOLECULES

25 Creating Mixtures Part 1 Pour cup A into cup B and mix the contents with a glass stirring rod. Observations/Questions Describe what you see in the cup. Draw a picture of what you see in the beaker. Using any means necessary, try to separate the mixture back into its original parts. Was it possible to separate the mixture? Why or why not?

26 Creating Mixtures Part 2 Pour cup C into cup D and mix the contents with a glass stirring rod. Observations/Questions Describe what you see in the cup. Draw a picture of what you see in the beaker. Using any means necessary, try to separate the mixture back into its original parts. Was it possible to separate the mixture? Why or why not?
