Electrical+Energy

In this section, we will focus on how electric energy is produced and transformed. We will make various circuits and use Ohm's Law to explain current, voltage and resistance. Calculation of electrical costs will provide useful in your future and is an important concept we will tackle. Lastly we will look at how magnetism can produce electricity and how electricity can produce magnetism. To learn more about electricity, check out the link.

1 7. Friday 10/23 Finish activity on generators from yesterday. Once complete:
== Read the Electromagnetic and Inductioncites to provide an explanation of EM and the electromagnetic induction process. Answer the following questions: 1. How electromagnets are produced? 2. How do electromagnets produce current? ==

==1 6. Thursday 10/22 Generators- Check out the PhETsimulations for generators and transformers. Take various screen shots to assist your explanation of how each of the following work: 1. Pickup Coil 2. Electromagnet 3. Transformer 4. Generator. Use any form of media to submit your explanation. You may do this with a partner. ==

== 15. Wednesday 10/21 Discuss the questions to the power point on power and efficiency. Check out this video for more of an explanation of power. media type="file" key="B- Power.mov" align="left" width="420" height="420" ==

== Explore this website on electricity. Once complete take the "chapter quiz" and take a screen shot of your correct answers. Finish for homework if needed. No need to pdf. I will check in class tomorrow. ==

doc. Be sure to finish the hand crank generators if needed.
== 13. Monday 10/19 Hand-Crank Generators. According to the conservation of energy law, energy cannot be created or destroyed, it transforms. This activity will provide various example of how mechanical (kinetic) energy is transformed into electrical energy. ==

== Monday 10/12 One more day with circuit. Although may of you have a good understanding of circuits, here is one more assignment to help guide your learning. You will use pHET but use the DC/AC circuit. Here you will not only examine DC circuits but include AC and capacitors. ==

==6. Wednesday 10/7 Finish the phet lab on series circuits. Once completed, the series start B5-EE Parallel Circuits. ==

==5. Tuesday 10/6 The purpose of this activity is to engage students in creating and manipulating circuits to determine the effect on current. Students will compare Ohm's Law to the actual circuit to prove it validity. Use the phet website to create a circuit. Follow the assignment EE-Circuit Construction on the network and complete.==

==4. ( Mon 10/5) Check out the Powerpoint on Electricity and using Ohm's Law. Use AC-DC Current link to help you answer the critical thinking question on the two types of current. Which type of electricity powers our house? How about our iPods? HW- Complete quia on Ohm's Law practice problems. You must log in for credit and you can take it as many times as necessary.==

==3. (**Friday 10/2**) Go to phet and look at the Use the OmniGraffle assignment explaining what happens as you adjust V, I and R. Take screen shots to aid in your description. You will find the editable assignment on the network.You are not limited to the template I have provided--you may change it to assist as needed. Once you understand how Ohm's law relates the variables, checkout Resistance in a Wire Use will be responsible for knowing the formula for Ohm's Law however the resistance equation will not be asked.PDF your assignment and use the hand-in robot by the end of class.==

==2. Thursday 10/1 Check out the Bill Nye Video Clip media type="file" key="B-Bill Nye EE.mov" width="300" height="300" and explain the water analogy that Nye relates to Electricity. With a partner or alone create your own analogy and post it to our Discussion Page. In order to do this you will need to create a wiki account.==

==1. Monday 9/29 The first assignment you will try is to make a light bulb light with nothing other than a wire, battery and light bulb. Follow the assignment guidelines ==
