9 Physical Properties & Physical Changes 17

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

Property vs. ChangeWhat is the difference between a property and a

change?

Discuss with your table partner and come up with an answer to write in the box…

What is a Physical Property?A characteristic

of an element or substance that can be observed or measured without changing its identity or structure.

Use your 5 senses OR scientific measurements to describe or measure…

What is a Physical Change?A change that

takes place without changing the identity or structure of the element or substance

EXAMPLES:DissolvingPhase changeChanging shapeWhat are some

other examples?

DENSITY

Mass per volume of a material, or how much “stuff” is packed together in specific area.

Formula to calculate density:d=m/v

SOLUBILITY

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

Solubility Side Note:Solvent = the substance that does the dissolving

Solute = the substance that dissolves

Insoluble = doesn’t dissolve

BOILING POINT

The temperature at which a liquid changes to a gas.

MELTING POINT

The temperature at which a solid changes to a liquid.

MAGNETISM

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

MALLEABILITY

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

Malleability Side Note:You may also hear the

word ductile or ductility

Ductility = the ability of a material to be stretched into a wire

CONDUCTIVTY The ability of a material

or substance that allows electricity or heat to flow through it easily. Most metals are good conductors.

SPECIFIC HEAT

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

WARM UP:Write your homework – leave it out to be

stamped.Find your test on the front counter and

complete the yellow data tracker. Staple them together and put them back on the front counter.

If you have your parent signature please get it out to be checked

10 Chemical Properties & Chemical Changes 18

Chemical Change Mini Labs (ONE from the group gets turned in for a grade – tape into notebook when returned)

19

What is a Chemical Property?

A characteristic that gives a substance the ability to change into a new substance…BUT the chemical change has to be happening to see the chemical properties!

CHEMICAL REACTIVITY

The ability of a material or substance to react with another material or substance and form something entirely different.

TOXICITY The degree to which a chemical can harm an organism.

FLAMMABILITY

The ability of a material or substance to burn or start on fire easily.

REACTIVITY WITH OXYGEN

The ability of a material or substance (usually metals) to react with oxygen and cause them to rust, corrode, tarnish, or combust.

What is a Chemical Change?A change that

results in the production of a new substance and cannot be reversed.

EXAMPLES:BurningRustingCookingWhat are some

other examples?

Evidence of a Chemical Change/Reaction:

Color changes – color appears or disappears

Temperature changesGas/gas bubbles producedFire/flame/light produced or explosion

Precipitate is formed – a solid or solid particles forms out of 2 liquids

HomeworkDo some research and make a list of 5

ORIGINAL examples of physical changes and 5 ORIGINAL examples of chemical changes that we have not discussed in class! Complete = 100 Incomplete = 70

Labs to Examine Chemical Changes

Mini Lab 1: Make your prediction based on the items you see the teacher has…

Watch closely…keep watching!Write your observationsWhat was your “hint” that a chemical change occurred?

FRIENDLY REMINDERS!!**Absolutely none of the lab chemicals should

come in contact with your mouth, eyes, or be breathed deeply!!

**Appropriate behavior at all times!**This is a group grade, so put everyone’s name

at the top of your paper right now.**You MUST complete the materials and

prediction boxes BEFORE you do the experiment!!!

GROUP 1 = SINK 1GROUP 2 = SINK 2GROUP 3 = SINK 3 ETC…GROUP 7 & 8 = SHARE A SINK

Group Roles Leader: Reads the directions for each lab,

keeps group on task and following directionsMaterials/Clean Up: collects, returns, cleans

and disposes of materials Data Discussion Leader: Ensures there is a

conversation about each data table to share information.

Quality Management: Ensures every student has detailed quality answers written in complete sentences using scientific language. REMEMBER, ONLY ONE WILL GET LAB GUIDE FROM YOUR GROUP WILL GET COLLECTED AND THAT WILL BE EVERYONE’S GRADE!!

Mini Lab 2:Send your materials person to get a cup of milk, a cup of vinegar and a stir stick

Pour the vinegar into the milk and stir it like you mean it!

Observe and record any changes that occur at this time.

Send your materials person to BRING THE MILK CUP BACK UP TO THE COUNTER and throw the stir stick and vinegar cup in the garbage.

Mini Lab 3:Send your materials person up to pick up a

ziploc bag with baking soda in it for each group

Use the graduated cylinder to measure about 30 mL of vinegarAdd the 30 mL of vinegar to the baking soda

in the bag and SEAL THE BAG IMMEDIATELYObserve and record any changes that occur.Rinse your graduated cylinder and throw the

zip lock bag in the trash AFTER YOU HAVE DUMPED THE CONTENTS INTO YOUR SINK.

Mini Lab 4:Send your materials person up to get a

MYSTERY test tube for each group memberUse the eyedroppers to add an eyedropper

full of the cabbage juice (purple liquid) to each test tube…DO THIS ONLY ONCE

Observe and record any changes that occurWAIT FOR FURTHER INSTRUCTIONS!!!Rinse your test tubes and return them to

the test tube rack. Flush your eyedroppers with water. Rinse your bin & dry it! Clean up any spills at your group!

Mini Lab 5:Send your materials person to the sink to get

approximately 5 ml of water in your graduated cylinder

Put the water into your film canister & close the lid!

Break one Alka-Seltzer tablet in half and hold it up in the air!

ONCE WE ARE OUTSIDE…Put the Alka-Seltzer tablet into the film

canister and snap the lid TIGHTLYQUICKLY put the canister on the ground CAP SIDE DOWN AND STEP BACK!

Your lab bin should be clean and should contain all of the supplies it did

when you started!Clean, dry plastic bin1 graduated cylinder1 bottle of vinegar1 small beaker of cabbage juice2 pipettes (eyedroppers)1 packet of Alka-Seltzer1 film canister
