Blogs are an attempt to make you reflect on and self evaluate your performance in lab.  Review the experience and tell how you reacted, what you did, and what you learned.
Prior to answering the guided questions try to think about what you are feeling when you are preparing for your lab experiences. What skills did you need for the lab?
When blogging, try to reflect on the following:
Procedure/instrument you that used today
Correct performance of the procedure or use of the instrument
Importance of correctly performing the procedure or using the instrument.
Reevaluate what you will do in the future concerning the procedure related to the knowledge you have gained.
What you will do to change
What you need to do to build on your learning
How your procedure, instrumentation affected your patient partner.
