Monday, Feb. 1st 1 Bell-ringer: Get out notebooks and folders and open to your “Electrical circuits” notes. Agenda: Complete “Circuit Drawing Practice” worksheet QUIZ TOMORROW! Finish “Magnetism and Electricity” notes Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. (S.7.PS.8) Objective:

Series Circuit Current has only one loop to flow through. Examples: light bulbs, holiday lights Contains two or more branches for current to flow through. Examples: homes, automobiles Parallel Circuit Complex circuit: a circuit composed of both series and parallel circuits

Tuesday, Feb. 2nd 3 Bell-ringer: Study your “Electrical circuits” and your “Circuit Drawing Practice” for the quiz today. (5 minutes) Agenda: Bell-ringer Quiz “Magnetism and Electricity” notes Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. (S.7.PS.8) Objective:

TUESDAY QUIZ! 1.What circuit has two or more branches for current to flow through? 2.What circuit has only one loop of current flowing through it? 3.Give an example of a series circuit. 4.Give an example of a parallel circuit. 5.Draw a parallel circuit with 2 light-bulbs, one battery, and an open switch that turns off one light bulb.

Magnetism and Electricity When electric current flows through a wire, a magnetic field forms around the wire. Wire Strength of magnetic field depends on the amount of current flowing in the wire.

Wednesday, Feb. 3rd 7 Bell-ringer: Discuss with your neighbor: 1.When electric current flows through a wire, a _____forms around the wire. Agenda: Bell-ringer Finish “Magnetism and Electricity” notes Begin “Gravity” notes Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. (S.7.PS.8) Objective:

Electromagnets– a temporary magnet made by wrapping a wire coil carrying a current around an iron core. – To increase strength of the magnetic field, add more turns to the wire coil (solenoid) or increase the current passing through the wire Electric motor – a device that changes electrical energy into mechanical energy – In a simple electric motor, an electromagnet rotates between the poles of a permanent magnet.

Direct and Alternating Current Direct Current (DC) – current that flows in only one direction through a wire. Example: a battery Alternating Current (AC) – reverses the direction of the current flow in regular patterns. Example: plugging a toaster into a wall outlet

Gravity Gravity– any two masses that exert an attractive force on each other – Gravity depends on mass and distance between objects Weight– gravitational force exerted on an object; measured in units called Newtons – The greater the objects mass, the stronger the gravitational force on it.

Projectile Motion Projectile– anything that is thrown or shot through the air – A projectile follows a curved path and has: and Horizontal Motion VERTICALVERTICAL M O T I O N

Centripetal Force Centripetal acceleration– acceleration toward the center of a curved or circular path – “centripetal” means toward the center Centripetal force– force acting toward the center of a curved or circular path
