Introduction to Chemistry I Take out a pen or pencil and notebook. Your phone should be in your bag! What materials will I need? What are the rules and expectations?

Materials Three ring binder or notebook Calculator Pen and/or pencil Username and password MEMORIZED

Classroom Rules: No food…..ever. Only water in a bottle with a lid. If I see your phone, I take your phone. Once you’re in the room, you stay in the room. Backpacks remain under your desk for the entire block.

Be responsible. Be prepared to work. Participate.

Grading Homework (~10%) – Completion grade – Late works will earn 50% of assigned value Classwork and Labs (~40%) – Should be your own work. Simply copying will not earn you any credit. Projects, Tests and Quizzes (~40%) – Periodic quizzes, Tests or Projects at the end of a unit – Each day a project is late 10% deduction in grade. Daily Participation (~10%): The following are behaviors that will help you earn participation points: -Following instructions and on task behavior -Answering and asking questions in both small groups and as a class. -Helping classmates and asking for help as needed.

Review of Matter Matter is anything that has mass and volume. – Mass is a measure of an object’s resistance to change in motion. – Volume is the amount of space an object takes up.

Notes: Physical Properties of Matter Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.

Examples of Physical Properties:

Notes: Density Density: The amount of matter in a certain amount of space. To measure density: – Measure mass. – Measure volume V = l x w x h = Units = cm 3 In order to calculate the density: – Density = mass / volume – Units = g/cm 3

Lab: Density Calculation Density: The amount of matter in a certain amount of space. In this lab: – Choose several blocks. – Measure mass. – Measure volume V = l x w x h = Units = cm 3 In order to calculate the density: – Density = mass / volume – Units = g/cm 3

Which is more dense? Explain using the words mass and volume.
