Imagine you are an exploratory astronaut looking for life throughout the universe. One day you encounter a planet that has no carbon present on its surface. However, your instruments register movement and a variety of other signs that make you think life exists on the surface.

Part 1: 
Look for an element on the periodic table that would act similarly to carbon. Once you have identified one, be sure to discuss the following in your justification. 
· Examine and discuss the outer electron shell and chemical bonding characteristics of this new element. 
· Specifically describe how the outer shell would make this new element bond as carbon does. 
· Then you should specifically discuss or draw two chemical reactions to form macromolecules with this different element. For example, make a molecule like glucose but without any carbons (replace carbon with your new element). Images will work great here; they can be hand or computer drawn or you may be able to find some on the internet. 
· Cite your references!
Part 2: 
Choose two of the defining characteristics of life and design an experiment to test each in your alien lifeform. Be sure that your design includes all the following points.
· Hypothesis
· Dependent and independent variables
· Control and experimental groups
· Standardized variables
· The specific type of data you would collect
· How you would analyze and present these data
· What pieces of data/evidence you would need to support your hypothesis. Alternatively, what evidence would disprove your hypothesis?
Remember to keep things simple and observable. You will most likely have to design 2 different experiments to test the different characteristics.
