Cycling+of+Matter

=Cycling of Matter - Part 1=

Energy Transfer

 * Solar energy is transformed into cellular energy by **photosynthesis**
 * Energy __cannot__ be created, or destroyed ONLY PASSED!
 * Most energy is lost as heat, but the rest is transferred to the consumer

Cycling of Matter

 * Certain types of matter exist in self-sustaining cycles, such as **nitrogen** and **carbon**
 * (this means that nitrogen and carbon can recycle themselves... kind of neat!)
 * Matter is continually cycling through ecosystems, but...

Organic Matter

 * is only the **matter** that forms a __continuous__ cycle
 * **Organic matter** is matter that contains atoms of carbon and hydrogen. They often contain oxygen and nitrogen atoms as well!
 * C, H, sometimes O and N... = organic matter!
 * Proteins, sugars and fats are all examples of organic compounds. Your body is made up of these compounds.

=__Thursday, April 5th, 2012__ Video Challenge:=
 * Read the notes above. Find at least 3 videos on the internet that explain the topics clearly. You might search for some of the following phrases in YouTube:
 * Energy transfer
 * Photosynthesis
 * Cycling of Matter
 * Organic Matter
 * You could also choose to find a video about **inorganic matter**, the **carbon cycle** or **nitrogen cycle**, as we will look at those tomorrow.
 * In a Microsoft Word document. You MUST:
 * Paste the links to at LEAST 3 YouTube Videos
 * Write 1 paragraph **FOR EACH VIDEO** about **why you chose that video** (did you like that it was a cartoon? did you like that it explained things without complicated words?) and **what you learned from the video**.
 * On a seperate page, paste the links to 7 videos you watched, and explain why you DIDN'T like about them.


 * Whoever finds the BEST video(s) that impress Ms. Harris the most, will win a prize (given out on Tuesday!).**
 * Good luck!**
