Course description

Please provide a detailed course description. All laboratory science courses should include a course description; course syllabus; hours spent per week completing laboratory assignments and list of physical laboratory experiments.

†

The Introduction to Chemistry and Physics is taught with the Modeling Instruction for Physical Science curriculum.†† Throughout the course; students will be practicing science using the Science and Engineering Practices; per the AZ Science Standards. Since the practices are embedded throughout the year; students jump right into† Motion.

Students conduct labs or investigations; collaborate with peers; and share findings in a white board meeting.

Describing Motion:† in this unit; students† describe motion using the terms position; distance; and displacement; speed and velocity.† They analyze motion graphically; and create position- time graphs. They determine if an object is experiencing constant velocity or constant acceleration.† They derive the formulas for velocity and acceleration from lab work; and use the formulas to solve a variety of motion problems.

Labs:

Constant Motion Lab

Cart on an Incline

Constant Velocity Lab Practicum: Dueling Buggies

†

Causes of Motion

In this unit; students investigate Newton?s Laws and demonstrate an understanding that a force is required to change velocity; not produce motion. Students demonstrate force interactions between agent and object; and express Newton?s 3 law in terms of force pairs.† Students show net force as a vector sum of forces.

Labs:

Broom Ball

Demonstrations and Force Identification and Notation

Gravitational Force vs Mass Experiment

Forces Between Objects

Newton?s 2nd Law: PhET Simulation

†

Causes of Change

In this unit; students develop an understanding of energy interactions in terms of transfer and storage.† They develop the concept of relationships among Kinetic; gravitational; elastic potential; dissipated; and chemical as modes of energy storage.† They will develop a system schema to represent the relationships between energy transfer and energy storage.† There will be an emphasis on energy pie charges† to represent energy storage.† Students will apply conservation of energy to mechanical systems; and will identify working; heating; and radiating; as energy transfer mechanisms.

Labs:

Physics Capstone Engineering Design Project

Question: How are Newton?s laws used in engineering and technology to serve human needs?

Objective:† Design; evaluate; and refine a device that will minimize the force on one large grade A egg (raw) and keep it from breaking when dropped vertically from a scissor lift.

†

Physical Properties of Matter

In this unit; students develop a definition for the mass of an object; and develop; from experimental evidence; the law of conservation of system mass.† Students will then develop an operational definition volume; and then develop the mathematical model for v=lwh and v = ah.† They will determine volume of irregular solids through displacement; and will then investigate the relationship between matter (amount of stuff) vs volume.† Students will use the graph developed to derive the formula for density. Students will recognize density as a characteristic of matter; used to identify various substances.† Students then develop a particle mode for matter; and can state the basic tenets of the Kinetic Molecular Theory as they relate to a gas.† Finally; students will relate physical properties to the arrangement of particles; will use particle diagrams to explain motion and density differences; will infer how forces between particles cause cohesiviveness; and distinguish between a pure substance and a mixture; element vs compound.

†

Energy and Particles

In this unit; students will relate observations regarding the addition of energy by warming to particle motion.† They will state the basic tenets of the Kinetic Molecular Theory as they relate to gases; and recognize energy as a conserved substance-like quantity.† They will recognize energy is stored in an object or system in several ways; such as thermal and phase; and will consider the arrangement of particles in each. They will describe ways energy is transferred; such as heating; working; and radiating.† They will investigate heating and cooling curves; and will be able to explain what is happening at each point along a curve.

Particles

In this unit; students will describe evidence that supports the idea that simple particles have a charge. They will describe evidence through the years to show how the atomic theory has evolved.† Students will investigate and give evidence that distinguishes ionic from molecular or atomic solids.† Students will write formulas for ionic or molecular substances; and will determine if a substance is molecular or ionic. Students will also describe alpha; beta; and gamma radiation; and compare the decay processes of different types of radiation.

Labs:

Sticky Tape Lab

Mendeleev?s Periodic Chart

Kernalite Radioactivity Lab

†

Particle Interactions

In this unit;† students will distinguish between metals and non-metals and will identify valeance electrons for each Family/Group 1-8.†† They will describe evidence that distinguishes ionic from molecular or atomic solids. Given formulas; students will be able to write its formula; and given the name or formula; they will determine if it is ionic or molecular.

†

Labs:

This unit has Activities rather than ?labs?- as students will be analyzing crystal structures of Elements and Compounds

†

Reactions

In this unit; students describe chemical changes; and recognize that the total number of particles can change during a reaction because of differences in the bonding rations of each substance. They will recognize that the total number of atoms does not change during a reaction because every reactant atom must be included in a product molecule.

They will write balanced equations and explain that the coefficients in a chemical equation describe the quantities of the elements and compounds involved.

They will observe patterns in the way substances react; such as synthesis reactions; decomposition reactions; combustion reactions; single and double replacement reactions; as well as pH scale.
