Waves Draw a standing wave. Label important terms (amplitude, wavelength, node, etc)
Waves Compare longitudinal and transverse waves. Give an example of each.
Waves Consider how waves are formed in the ocean. How does a tsunami form? Using this information draw some conclusions about the relationship between important terms ex: velocity and amplitude – how are they related? (Think: what causes the wave to grow?!)
Waves Define the terms and discuss how they are related. Also, what are the units of each? Wavelength Frequency Period
Waves What is the wavelength of the wave below. What is the velocity of the wave if its frequency is 4 Hz?0.2m- 0.2m 6m
Waves Student A is on the Huntington Beach Pier in California and notices 11x World Champion Surfer Kelly Slater in the ocean below sitting on his board waiting for a wave. As a water wave passes, Kelly bobs up and down, rising to the top of a wave crest every 10s as he waits patiently for the perfect wave. Calculate the frequency of the passing waves. Calculate the speed of the passing waves.
Waves Student B shakes a slinky to create a standing wave that looks like this: 5m What is the wavelength? If we shake it 3x per second, what is the speed of the slinky wave?
Electricity Units! Coulomb? Current? symbol? Current is measured in? Unit of energy? Units of Voltage? Measured in? Which concept connects current and voltage?
Electricity Energy transformations! Where did the energy come from to light our bulb? What type of circuit do we need?
Electricity Circuits! Compare and contrast the two types of circuits. Draw an example of each.
Electricity What equipment can be used to measure voltage and current? How should they be hooked up to the circuit?
Electricity What do the squiggly line symbols in our drawings represent? Define this term. What is it measured in? What law helps to define this term.
Electricity Use Ohm’s Law to determine the relationship between resistance, voltage, and current. (If one goes up, what happens to another?) What was our other mathematical equation from Chapter 6?
Electricity An Xbox operating at 240V draws 2A of current. Determine resistance and power.
Electricity What is the power output of a Mustang GT with a 12V battery that supplies a current of 10A to its ignition?
Electricity A 100W light bulb runs on 200V and draws 2A of I. Running for 5 minutes (300s), how much energy is used in this time?
Electricity Draw a parallel circuit with 3 identical light bulbs with a battery that provides 9V and a current of 3A. What is the current and voltage for each bulb?
Electricity Draw a series circuit with 3 identical light bulbs with a battery that provides 9V and a current of 3A. What is the current and voltage for each bulb? Based on these two answers – which way are houses wired? Why?
Electricity How do we control all of this electricity? What device(s) are used? How are these different?
Electricity Chapter Challenge Math! If I use my 100W Hitachi drill for home renovation work for two hours a day, how many kW hours do I use in a day? *1 kW = 1000W

Magnetism Review your exams! Draw the magnetic field of a bar magnet. Draw the magnetic field around the current carrying wire indicated below: (Left Hand Rule!) Current
Magnetism Which was does the North pole of a compass point? Why? Draw the bar magnet of Earth to substantiate your answer. Inducing Currents… “breaking out of jail” question from the exam! Which action does NOT produce a current? Which actions do?
Magnetism List three ways to increase the strength of a solenoid. How are a motor and a generator different? What happened when I used two hands cranks in my demo?
Magnetism Think back to our generator Investigate… what equipment did we use? How did we use this equipment to generate electricity?
