5. Chemistry Tutoring Tuesday mornings from 8:15 – 8:45

6. FRIENDLY REMINDERS!! **Anyone sensitive to strong odors? Let me know if any of the odors are bothering you at any point during the labs today! **Absolutely none of the lab chemicals should come in contact with your mouth, eyes, or be breathed deeply!!

8. PHYSICAL PROPERTY Any characteristic of a substance that can be observed without changing the identity of the substance. Every substance has its own set of physical properties.

9. Physical Properties Used to observe and describe matter or elements. Can be observed or measured without changing the structure of the element. Use your 5 Senses… appearance, texture, color, odor Scientific Examples… melting point, boiling point, density, solubility, malleability

10. DENSITY Mass per volume of a material, or how much stuff is packed together in an area.

11. SOLUBILITY A measure of how much of a substance dissolves in a given amount of another substance.

12. BOILING POINT The temperature at which a liquid changes to a gas.

13. MELTING POINT The temperature at which a solid changes to a liquid.

14. SPECIFIC HEAT The amount of heat or energy needed to raise 1 gram of a substance by 1 degree Celsius (1  C).

15. MAGNETISM A force of attraction or repulsion that exists between like and unlike poles.

16. MALLEABILITY The ability to be hammered, shaped, or rolled into thing sheets. Most metals are malleable.

17. ELECTRICAL CONDUCTIVTY The ability of a material or substance that allows electrons to flow through it easily. Most metals are good conductors of electricity.

18. Physical Change A physical change takes place without the element’s chemical structure changing. EXAMPLES: Dissolving Phase change (solid, liquid, gas) Changing shape

19. Chemical Properties Describe a substance’s ability to form new substances Examples: Flammability Ability to rust Chemical Reactivity

20. Chemical Change Production of a new substance Cannot be reversed

21. Hints that a Chemical Change/Reaction has Occurred: Color changes - color appears or disappears Temperature changes Gas/gas bubbles produced Fire/explosion Precipitate is formed – a solid forms out of 2 liquids

22. Every element on the Periodic Table has it’s own set of physical & chemical properties, that is what makes their “personalities” unique!!!

23. Labs to Examine Chemical Changes

24. Mini Lab 1: Make your prediction Teacher Demo…watch closely! Write your observations

25. Group Roles Leader: Runs directions for each lab, keeps group on task Materials: collects & returns materials; assists in clean up/material disposal Clean Up: assists in collection; cleans up materials/disposal Data: data table is properly completed by all group members, make sure observations are detailed You can rotate roles after each investigation

26. Mini Lab 2: Send your materials person up to pick up a ziploc bag with baking soda in it for each group member Use the graduated cylinder to measure about 20 mL of vinegar Add the 20 mL of vinegar to the baking soda in the bag and SEAL THE BAG IMMEDIATELY Rinse your GRADUATED CYLINDER and throw away the ziplock bag

27. Mini Lab 3: Send your materials person up to get a test tube for each group member Use the eyedroppers to add an eyedropper full of the cabbage juice (purple liquid) to each test tube Observe and record any changes that occur Rinse your test tube and return it to the test tube rack. Clean up any spills at your group!

28. Mini Lab 4: Send your materials person to the sink to get 5 ml of water in your graduated cylinder Put the water into your film canister Break on Alka-Seltzer tablet in half Put the Alka-Seltzer tablet into the film canister and snap the lid TIGHTLY QUICKLY put the canister on the ground CAP SIDE DOWN AND STEP BACK!

55. Instant Gratification Review You will all start on the same review page and work your way through them (total of 5) to create a review packet The first person that completes the first page with 100% becomes my assistant As you complete a page you must come up and have it checked by myself or my assistant

56. The Catch… Once you get 2 wrong or less per page, you can either chose to receive a ticket and take your chances in the drawing for homework passes or candy OR chose instant gratification of a piece of candy Take the next page and repeat the process You may use your notes and the book, AND you can make corrections and resubmit the same page FOR CANDY ONLY, BUT YOU MAY NOT WORK WITH OTHER PEOPLE!

57. Do You Need Help? On the back of each page make a list of concepts you may need help with…BE SURE TO ASK ME OR COME TO TUTORING ON TUESDAY MORNING!! DRAWING FOR TICKETS…
