Jump Start *If you were asked to describe a piece of fruit to a person who has never seen this type of fruit before, what would you tell the person? *Be descriptive in your language. *Please DO NOT tell you classmates which fruit you have chosen to describe, because you will be sharing your response later. *Any volunteers want to read their fruit description to the class? (Please do not tell us what your fruit is before, we want to guess).

Secret Sack PROCEDURE: Each Lab Group will receive a sealed paper sack containing a mystery object. Do not open the sack! For about five minutes, make as many observations about the object as you can without opening the sack. You may touch, shake, or listen to the object through the sack. Record your observations.

Secret Sack Continued ANALYSIS: 1. At the end of five minutes, discuss your findings with your partners. 2. List the object’s properties that you can identify. 3. Make another list of properties that you cannot identify. Then make a conclusion about the objects identity. 4. Share your observations, you list of properties, and your conclusion with the class. Then, open the sack. 5. Did you properly identify the object? If so, how? If not, why not? Record your answers.

Warm-up Take out your notes if you did not glue in the pages do so right now. Copy tonight’s homework in your planner. We will finish sharing our fruit. We will continue the physical property notes and review volume and mass today

Warm-up Place your homework on your desk Copy tonight’s homework in your planner. Open your notebook to page 26. Write the title “Matter Properties Reflection”

Introduction to Matter Physical Properties:

Essential questions How are the physical properties of matter used to compare pure substances? What is density? What are the 4 states of matter? What is solubility?

What are Physical Properties? Something that can be observed or measured without changing the matter’s identity. What are Physical Properties?

Name some physical properties of this apple

What are some specific Physical properties? Thermal conductivity- how well a substance transfers heat State of matter- solid, liquid or gas Density- how much mass is in a given space Density=mass/volume or D=m/v Solubility- how well a substance dissolves in another substance. What are some specific Physical properties?

We will discuss the fourth state briefly in the states of matter section of this unit

Solubility

Ductility Ability to shape into wires

Malleability Ability to mold into flat sheets and Shapes.

D=M/V

How will density help figure out what a substance is? In liquids, densest liquid sinks to the bottom, least dense floats on top. Solids can be checked against water’s density (1g/cm3), if solid floats it is less than 1g/cm3, if it sinks it is more than 1g/ml How will density help figure out what a substance is?

Making Sense of Density Quick Lab (1)Does the density of a material vary with volume? (2)Material: 1 crayon with paper removed, paper towel, balance graduated cylinder, approximately 50mL of water. (3) Procedures: Create a small chart to record your data Item Mass (g) Volume (cm3 ) Density

Making Sense of Density Quick Lab Use a balance to find the mass of the whole crayon Add enough water to a graduated to cylinder to complete submerge the crayon Use water displacement to measure the volume of the crayon. Record your results in the table. Use the density formula to calculate the density. Break the crayon into two pieces. Repeat procedures for the other two crayon pieces. Record your results in the table.

Data Analysis and Conclusion For the object you tested, compare the density of the whole object with the densities of the pieces. Use your results to explain how density can be used to identify a material.

Compare and Contrast Density QUICK LAB (1) Material Getter: Beaker with 200ml Water, Golf ball and ping pong ball, triple beam balance or electronic balance (2) Lab Initiator: Drop the golf ball into the water and observe the displacement Drop a ping pong ball into the water and observe (is there any displacement?) (3) Data Collector: Mass both balls on the balance and record both the mass. (4) Discussion Leader: What do they have in common? Why do they not react the same in the water? What causes the difference?

How do you calculate Density? (the broken heart equation) What you need 1. Mass=m grams 2. Volume=V cm3, ml, m3, L Formula How do you calculate Density? (the broken heart equation) m D= D= V

Journal Activity In your journal complete the following activity Yesterday I learned about__________________ With my class. The first thing we learned was ____________. Next, _____________________ ____________________. Then, _____________ ___________________. I also learned that ____ _____________. Next time we study _____________________________________, I want to learn more about ______________.

Journal Activity In your journal complete the following. Summarize today’s lesson in one or two sentences.

Density Demonstration: Coke vs Diet Coke Coke-dietcokegr6_sci_26_demo[1].pdf Demo with soda’s in large beakers. Students will calculate the density in notebooks/binders.

What are physical changes? When matter is changed from one form to another with out changing its identity. Example: water Water to ice, water to steam, steam to water What are physical changes?

Physical change of state

More Physical change examples: Shape changes, like crushing a can, melting a popsicle, dissolving kool-aid, melting butter. These have changed shape, but are the same type of matter. More Physical change examples:

Objectives Review Identify and compare the physical properties of matter to include density, melting/boiling points, states of matter, and solubility. Explain what happens to matter during a physical change. A substance undergoes a physical change, but its identity stays the same. Also…List the six examples of physical changes. Breaking, melting, freezing, cutting, crushing, and dissolving.
