2. Chapter 10 Lesson 1: Classifying Matter Textbook Pages 349 – 355 Date: 9/24/15 Add the new notes to your table of contents, and then turn to the next clean page and set up your title and date

3. How do you classify matter? Classification is the grouping of items based on shared characteristics In science we classify everything around us! Classification Activity: Working with your partners you will classify the 10 items on the next slide into 3 different groups Each group must have a title, and underneath you must explain the “rules” you used to classify the items

4. Set up your notes for this activity as modeled below:

6. Lesson 1-1 MatterMatter is anything that has mass and takes up space. Understanding Matter We need to add "matter" to our index before moving forward, turn to the page in your index with the letter "m" and wait for Mrs. Stabler's directions

7. After defining a key term in your class notes it must be added to your index Begin by finding the correct section –We are adding matter, so we need to find the box marked "M" Skip a space under the letter "M" and write the word "matter" followed by the page number in your INB that it can be found on Adding key terms to your index

8. Lesson 1-1 Everything you can see is matter, but some things you cannot not see, like air, are also matter. An atom is a small particle that is a building block of matter. atom Understanding Matter (cont.) Add atom to your index just like we did for matter, be sure to put it in the "A" section and write the page number

9. Lesson 1-2 The center of the atom is called the nucleus. Inside the nucleus are two subatomic particles: –Protons which are positively charged, and –Neutrons which are neutral or have no charge The area surrounding the nucleus is called the electron cloud. One type of subatomic particle moves around inside the electric cloud: –Electrons which are negatively charged Atoms

10. Lesson 1-2 Within each atom the number of protons, neutrons, and electrons are the same –For example an Oxygen atom has: 8 protons, 8 neutrons, and 8 electrons But not all atoms have the same number of protons, neutrons, and electrons. –A Lithium atom is different from an Oxygen atom, a Lithium atom has: 3 protons, 3 neutrons, and 3 electrons Atoms that have different numbers of protons differ in their properties.

11. Lesson 1-3 An element is a substance that consists of just one type of atom.element Because there are about 115 known elements, there are about 115 different types of atoms. Each type of atom contains a different number of protons in its nucleus. The number of protons in an atom is the atomic number of the element. Add element to your index, be sure to put it in the "E" section and write the page number Add atomic number to your index, be sure to put it in the “A” section and write the page number Elements

12. Lesson 1-3 Each element on the periodic table consists of just one type of atom.

13. Each element has its own box on the periodic table Understanding the Periodic Table The information found in the box, as well as its location can tell you a great deal of information about the element

14. We are going to use what we have learned about atoms of different elements to draw some atomic models. First let’s set up our notebook: –Each of you will receive two half sheets of paper, use the tape to put them into your note book on a clean page so that they flap open in the middle of the page –Great! Now we can draw atomic models underneath Interactive Notebook Activity

15. Together let’s do Carbon… Now complete the rest with your partners First let’s make a key for the subatomic particles at the top of your paper ParticleColor Protonred Neutrongreen Electronblue

16. Lesson 1-3 Substances (cont.) How do atoms of different elements differ? First write your answer down then share with your partners

17. Lesson 1-3 Atoms can combine and arrange in millions of different ways. These different combinations and arrangements of atoms are what makes up the various types of matter. There are two main classifications of matter: –Substances and, –Mixtures Classifications of Matter

18. Lesson 1-3 A substance is matter with a composition that is always the same.substance Substances are chemically bonded and cannot be separated by physical means This means that a given substance is always made up of one or more atoms in the same combinations. Two type of substances are elements and compounds. Substances Add substance to your index, be sure to put it in the "S" section and write the page number

19. Lesson 1-3 A compound is a type of substance containing atoms of two or more different elements chemically bonded together.compound The combination of symbols and numbers that represents a compound is called a chemical formula. A compound often has different properties from the individual elements that compose it. Add compound to your index, be sure to put it in the "C" section and write the page number

20. Lesson 1-3 What is the difference between elements and compounds? If a substance contains only one type of atom, it is an element. If it contains more than one type of atom, it is a compound.

21. Lesson 1-4 A mixture is matter that can vary in composition.mixture Mixtures are combinations of two or more substances that are physically blended together. The amounts of the substances can vary in different parts of a mixture and from mixture to mixture. Mixtures Add mixture to your index, be sure to put it in the "M" section and write the page number

22. Lesson 1-4 A heterogeneous mixture is a type of mixture in which the individual substances are not evenly mixed.heterogeneous mixture The individual parts of a heterogeneous mixture are visible Because the substances in a heterogeneous mixture are not evenly mixed, two samples of the same mixture can have different amounts of the substances.

23. Lesson 1-4 A homogeneous mixture is a type of mixture in which the individual substances are evenly mixed.homogeneous mixture In a homogeneous mixture, the particles of individual substances are so small and well-mixed that they are not visible, even with most high- powered microscopes. Mixtures (cont.)

24. With your partners: Make a list of 5 heterogeneous mixtures, and a list of 5 homogeneous mixtures

25. Lesson 1-4 To dissolve means to form a solution by mixing evenly.dissolve Homogeneous mixtures are formed when one substance dissolves into another A homogeneous mixture is also known as a solution. Add dissolve to your index, be sure to put it in the “D" section and write the page number

26. Lesson 1-4 Mixtures (cont.) How do mixtures differ from substances? First write your answer down then share with your partners

27. Lesson 1-6 Tape the decision chart into your notebook, it will help you to classify matter as we continue forward in Chapter 10

28. Lesson 1 - VS A substance has the same composition throughout. A substance is either an element or a compound.

29. Lesson 1 - VS An atom is the smallest part of an element that has its properties. Atoms contain protons, neutrons, and electrons. The substances in a mixture are not chemically combined. Mixtures can be either heterogeneous or homogeneous.

30. Lesson 1 – LR1 A.atom B.element C.mixture D.substance Which term describes matter that can vary in composition?

31. Lesson 1 – LR2 A.atomic number B.chemical formula C.mixture D.substance What is the combination of symbols and numbers that represent a compound?

32. Lesson 1 – LR3 A.homogeneous mixture B.heterogeneous mixture C.chemical formula D.compound Which term refers to a type of substance containing atoms of two or more different elements chemically bonded together?

33. Lesson 1 - Now 1.The atoms in all objects are the same. 2.You cannot always tell by an object’s appearance whether it is made of more than one type of atom. Do you agree or disagree? 1.The atoms in all objects are the same. 2.You cannot always tell by an object’s appearance whether it is made of more than one type of atom.
