"Batteries in your Daily Life "
(Consider This 8.1) -- By definition, a battery is a system that
converts chemical energy directly into electrical energy. We will begin
our study of Chapter 8 by examining the Electron Transfer that
takes place in batteries - the dry cell, the Lithium-iodide battery, the lead
storage battery - and what happens when those batteries run out of energy.
- To what extent do you depend on electron transfer (from batteries) in
your daily life?
- How many of those things use batteries as the main power source? as a
back-up power source?
- Which batteries are researchable? which ones are not?
- What kind of batteries are in your cell phone?
Check out CT 8.5!
- What happens to those batteries when you throw them away?
- Is it OK to toss a used battery in the trash can?
Check this
link to information about the Federal Battery Act
- Want info on batteries?
- What about the new
Oxyride battery (CT 8.6) developed in Japan for Panasonic?
- What's the best battery for a specific function?
On Wednesday, April 13 we will examine the extent to which
we each depend on electron transfer (in the form of batteries) in consumer
products. This will be a group assignment done in class. You
will want to print the information on Lithium ion batteries (CT 8.5), Oxyride
batteries (CT 8.6) and the summary of the Federal Battery Act from the EPA web
site. Bring the information to class; as a group, you can tease out the
relevant information on Monday. [This activity is based on CT 8.1, 8.5, 8.6
& 8.8] If you missed class that day, it would be prudent to
do this exercise as a journal
entry. It may come in handy for the final.
