A new story begins...

The Story of Electricity... watch the first part of this documentary (30 minutes out of about 60)

And finish the first 5 pages of your electricity lab, neatly please, which we began in class. 

If you have not already done so, finish up the open book test for the last chapter (see last Monday's blog for instructions and printout.)

And then there was light!

A little more about heat energy, before we go on:

And also a little al-Gebra => print this page. al-Gebra B=UG

And then here's a review worksheet, which is more like an open book/open Google TEST:
Open Book Test on Energy & Heat   Turn in by Monday, but do not procrastinate! You will still have more homework assigned on Thursday.

Don't forget to test your mom and dad and sibs - Light the bulb with just a dry cell, a bulb and a foil wire!

You're Getting Hotter!!!

Textbook Reading: 6.2 Transferring Thermal Energy (pages 164-170)

 filling in the As You Read worksheet.

Here are some innovative solar ovens that may interest you:

Now the the difference between heat and temperature, please take notes:

Make two columns: one for temperature, one for heat.   Compare and contrast.

draw diagrams.  take notes.

--Did you see the image on page 163 of the calorimeter?  This is like the Cola-rimeter that we used in class!  Be sure to finish the lab worksheet as well.

And lastly...

The Heat Is On...

Compare your solar oven to different designs using different materials with this virtual SolarCooker. Print out this worksheet Comparing Solar Ovens; the columns are not labeled, but record the temperatures of each variation of solar cooker, both in degrees Fahrenheit and degrees Celsius, and give it a rating from 1-4. Find the cooker which uses the same materials as you did; what temperature did it  reach?    Find the oven which reached the highest temperature; what materials was it made from?

Write a paper with two paragraphs, describing how a solar oven works and why a solar oven could be an important tool in solving some of the world's energy problems among the poorest nations. . Here are some sites that might help you:

http://solarcooking.wikia.com/wiki/Why_solar_cooking_is_important

Your paper should be at least one page of writing, typed; include 3  images of  solar cookers that you find intriguing.

more on energy...

Please bring an empty shoebox to class on Thursday, if you can.  Find one and put it in your car NOW!  If a few of you can bring some aluminum foil, that would be great too.  We will be making solar ovens, soon anyway.

Tuesday's Homework (Part 1)**********************************************************

Here's energy!!!>>> 

and here's a short demo >>> Write a few  notes (plus a drawing) in your lab book explaining the demo; include the vocabulary words "potential/kinetic energy".

Next, a simulation:

Wednesday's Homework (Part 2)
Textbook reading:  Chapter 4.2 (pages 107-121) and fill in the review worksheet 

Returning...

Three weeks of vacation is soooooooo much better than two!  We really need it, to spend time with family and friends, to catch up on rest, to help mom a little extra, and yes, to prepare for going back to school. This last week will have a bit of homework  which I will post by Monday, and will include reading  chapter 4 - Energy.

And for those of you who did not turn in  the chapter 3 test on forces, please find it, do it, and turn it in!  If you have already forgotten it all, at least answer the questions " open book" but include a note saying that you used your book, because that is the honest thing to do.  If you did do the test but got a poor grade, why not re-take it now for a better grade and also good practice on test-taking skills?  For a new copy of the test,  print it out from here,

>>> and also reorganize your science binder and your lab books so that you will be ready for the New Year. Do not throw your old work away!

HOMEWORK DUE MONDAY< JAN. 13th>

For review:  Please take notes in your lab book as you watch.

And going forward...

and also...

(lotsa math here, try to follow it as best you can)

READING:  Textbook chapter 4, section 1: 

The Nature of Energy

and this worksheet (print out). 

Be sure to bring your calculators on Monday; we will be doing sum math!  oo-rah!
