- Working within SEM limitations
- Problem Solving
- Organization
- Scientific method

**Notes:**
Expanding student interest in science has always been one of the aims of GADGET 
GADGET also serves as a unique creative outlet for students.  
But even with wonderful, and creative ideas, students must consider the limitations of an SEM experiment. 
Limitations can included chemical restrictions, timing, and limited power and space. 
These limitations also require students to develop and improve their problem solving skills.  
GADGET not only encourages the use of problem solving skills but also show its role in research.
Completing a research experiment also requires great deal of organization.
Organization includes bringing people together to make a proposal to splitting the tasks necessary to  build an experiment.  
Doing research requires the use of the scientific method.  
Using the scientific method, GADGET allows students to ask their space questions and search for answers first hand, not in encyclopedias.
GADGET has allowed students to ask questions that go beyond what mig.  Our motto
