Physical Properties of Matter 8th Grade Science UNIT 1 Matter Day 2 August 31, 2017 Physical Properties of Matter 8th Grade Science

Warm-Up: (2nd entry on science starter sheet) Also, place your flash card in the box in front. Copy the question. Q). In the following picture, what is something that is matter and something that is not matter? EXPLAIN WHY.

Matter Plan for today: Science starter – Review E. Q. Mass, volume, and density discussion and notes Lab – Mass, volume, density Wrap-up

Warm-Up: (2nd entry on science starter sheet) COPY THE QUESTION: Q). In the following picture, name something that is matter and something that is not matter. EXPLAIN WHY.

Please take a couple of minutes and answer yesterday’s E.Q.

Write today’s date at the top of page 3 in your notebook Write today’s date at the top of page 3 in your notebook. Then copy this E.Q. Essential Question- What are physical properties of matter?

Homework: Make flash cards for terms: (2) Physical property (3) Mass (4) Volume Clip or rubber-band them with card #1 matter (in order).

Review: What is Matter? Anything that has mass and volume (takes up space). Examples of matter:

Matter Volume – The amount of space something occupies Mass - The amount of matter in something

Matter Matter can be described by using physical and chemical properties. Properties are characteristics of matter that make it unique.

Property = Characteristic Review: All matter has what two properties in common? There are many other unique properties of matter that can help us identify what type of matter it is. Mass and Volume

Turn to your vocabulary sheet.

2. Physical PropertY Def. – characteristics of matter that can be observed or measured without changing a substance’s identity. A.D. Ex. -color, mass, length, volume, density, state of matter, smell, texture, etc.

Observable Physical Properties Observable Physical Properties: Properties for which you can use your senses to get information about an object. If you can describe matter based on how it looks, feels, smells or tastes, you are describing the physical properties.

Examples of: Observable Physical Properties Color: The color of object can be seen and is a physical property of matter. Color can help identify a substance. For example, sulfur is usually yellow in color, iodine is usually red in color. Iodine Sulfur

Examples of: Observable Physical Properties Luster: Describes how a substance reflects light.

Examples of: Observable Physical Properties Texture: The way a surface feels.

Examples of: Observable Physical Properties Smell: The odor an object gives off can also help identify a substance. For example, sulfur has a rotten egg smell, vinegar has a very acidic smell, and chlorine has a very strong bleach smell.

There are also Measurable PHYSICAL Properties of Matter Measurable Physical Properties: Properties (characteristics) that must be measured with a tool (ruler, beaker, graduated cylinder, scale, etc.). Ruler Beaker Scale Triple Beam Balance Graduated Cylinder

Measurable Properties of Matter 3. Mass: (back to your notes) Def. the amount of matter that something is made of. A.D. Tool is a triple beam balance or a scale. A.D. Unit is grams (g) or kilograms (kg).

Which object has less mass?

DO NOT USE ANY OTHER MATERIALS OR GO ANY FURTHER *DO NOT USE ANY OTHER MATERIALS OR GO ANY FURTHER. ONLY DO WHAT YOU ARE BEING ASKED TO DO. TASK: 3 minutes - Find the mass of the binder clip and the pencil. write it on page 4. What tool did you use? Write it down. What unit of measurement? Write it down.

Measurable Physical Properties of Matter Weight: is the measure of how gravity is pulling on an object (mass). Gravity is less on the MOON!!! On earth, we just weigh you to calculate!

Mass = 50 kg EVERYWHERE Weight = 16.53 lbs. Weight = 100 lbs.

Measurable Properties of Matter 4. Volume: (there is another slide; write small on your vocab. sheet) Def. the amount of space an object takes up. A.D. –- Use the formula: LxWxH for a regular solid L(cm) x W(cm)x H(cm) = ______cm³ (centimeters cubed is the unit) *Don’t copy this (but DO remember it) -ALWAYS USE CENTIMETERS IN SCIENCE!!!!

Measurable Properties of Matter 5. Volume: (cont.) A.D. For Liquids, use a graduated cylinder; unit is mL (milliliters) A.D. For irregular solids, use a grad. cylinder and water displacement; unit is cm³

Measuring the Volume of Liquids: How to calculate: Use a graduated cylinder to find the volume at the meniscus. Material: graduated cylinder, beaker, flask How to read a graduated cylinder Must be at eye level to read. Must read at bottom of the curve. MENISCUS - bottom of the curve. Unit: mL or L for liquids or cm³ for solids

Measurable Properties of Matter Measuring Volume of Irregular Solids: Water displacement. Put water into a graduated cylinder and record volume. Place irregular solid into cylinder with water and record second volume. Subtract the two amounts. Initial volume (water only) – volume with irregular solid = volume of solid UNIT: water measured in mL, but since it is a solid object you’re Measuring, use cm3. 1 mL = 1 cm3

Measurable Properties of Matter Water Displacement

DO NOT USE ANY OTHER MATERIALS OR GO ANY FURTHER *DO NOT USE ANY OTHER MATERIALS OR GO ANY FURTHER. ONLY DO WHAT YOU ARE BEING ASKED TO DO. TASK: Find the VOLUME OF a textbook. Write your answer on page 4. What tool or formula did you use? Write it down. What unit of measurement did you use? Write it down.

Which object has GREATER VOLUME? Explain.

Wrap-up and evaluate Discuss with your group and: Describe the mass and volume of a ping pong ball compared to a golf ball. EXPLAIN your reasoning.
