  1. Materials: -PRIDE Card -IN -Pencil/Pen -Foldable Bell Work 8/25/14Number your paper from 1 to 5. See if you can determine what the following magnified photos are. 1. 2. 3. 4. 5.

  2. The Answers: 1. 2. 3. 4. 5.

  3. Learning Targets Target Tests 1. • Identify the function of materials we use in the science lab. • Utilize the metric system to make accurate scientific measurements. 2.

  4. Update your Table of Contents!! 21 8/14/14 The Metric System ?? 8/25/14 Minerals • Chemistry

  5. Why does it MATTER???? • Matter- anything that has volume and mass. • EVERYTHING that surrounds you is composed of matter! • There are 4 States of matter

  6. 1. Solids Examples: flowers, wood, the chair you are sitting in.

  7. 2. Liquids Examples-water, Gatorade, soda

  8. 3. Gases Examples-the sun is made up of many gases, smoke from a fire, water vapor in clouds

  9. 4. Plasma A gas that is composed of free-floating ions Example: solar winds

  10. What makes up matter? • All matter is made up of elements. • Elementsare made up of atoms. • Atomsare made up of protons, neutrons and electrons.

  11. A few Definitions… Matter  elements  atoms  particles (protons, neutrons, and electrons) • Matteris anything that has volume and mass. Everything in the physical world that surrounds you is composed of matter. • An elementis a substance that cannot be broken down into simpler substances by physical or chemical means. • Atomsare the basic building blocks of all matter and are made up of protons, neutrons, and electrons.

  12. How do we organize Elements? • There are 92 elements that occur naturally • Other elements have been produced in labs. • Each element is given a chemical symbol ex: H=hydrogen, Cu=copper • Elements are classified and arranged according to their chemical properties

  13. The Periodic Table is made up of Elements! • https://www.youtube.com/watch?v=xQu2eSeM66o Let’s take a closer look

  14. Elements are made up of atoms…..Let’s take a closer look! A particle with approximately the same mass as a proton A particle with a mass and a POSITIVE charge Made up of protons and neutrons A tiny particle with little mass and a NEGATIVE charge

  15. Atomic Number (number of protons OR electrons in an atom’s nucleus) Round this number when determining # of neutrons Atomic Mass (sum of protons AND neutrons) Why don’t we include electrons in the atomic mass? Symbol Element

  16. Practice! 1. What is Iron’s atomic number? 26 2. How many electrons does it have? 26 3. What is its atomic mass? 55.845 4. How many neutrons does it have? 56 – 26 = 30

  17. Let’s Practice!!

  18. Bell Work 8/26/13 1. How many states of matter are there? 4 2. What are the states of matter? Solids, liquids, gases, and plasma 3. How many naturally occurring elements are there? 92 Don’t forget to write the question too!!

  19. The Periodic Table of Elements ***Elements are arranged in columns and rows

  20. Columns • The vertical (up and down) columns of the periodic table are called groups or families. • Elements in the same group or family have similar characteristics or properties.

  21. Label each column on your Periodic Table

  22. Rows • The horizontal rows of the periodic table are called periods. • Elements in a period are NOT alike in properties.

  23. Label each row on your Periodic Table

  24. Groups/Families Periods • All the elements can be classified as: • Nonmetals • Metals

  25. Metals Non-Metals

  26. Quick Quiz (Uno) • What element is Group 2 and Period 4? Calcium • Is it classified as a nonmetal, metal or metalloid? Metal

  27. Quick Quiz (Dos) • What element is Group 8 and Period 4? Iron • Is it classified as a nonmetal, metal or metalloid? Metal

  28. Quick Quiz (Tres) • What element is Group 14 and Period 5? Tin 2. What is that element’s atomic number? 50 3. How many electrons does it have? 50 4. What is its atomic mass? 118.710 5. How many neutrons does it have? 118.710 – 50 = 68.710
