Carbon forms the basis of all life on Earth. It's also capable of forming many thousands of different and complex molecules. A favorite science fiction theme is finding a non-carbon based life form elsewhere in the universe. Usually, this is a silicon-based life form. Consider what you know about carbon, about its bonding, and about organic molecules. Do a little research, if necessary, and comment on the following: Why would silicon be a possible basis for alien life? Why do you think silicon isn't as "prolific" in its known molecules as carbon? What advantages and disadvantages can you imagine silicon-based molecules might have over carbon-based molecules in a very different otherworldly environment?

If you read any amount of science fiction, you’ll probably come up against the idea of alien life based on some element other than carbon.
