Lab+-+Investigating+Heart+Rate

**Design an investigation into a factor affecting heart rate**

 * Factors to avoid:**
 * temperature - this is not an enzyme lab, don't be boring
 * exercise - this has been done to death and it's not sufficiently challenging
 * any factors which cause harm or pain


 * When choosing your factor:**
 * make sure you have relevant theory, better a citation to base your work upon
 * make sure there is a physiological basis, this investigation can cross over to physcology too easily
 * consider ethical and safety issues


 * Research Question:** now write your own


 * Things to remember when building your design:**
 * Be specific when you define your IV and DV and make sure they are measurable
 * Know what measuring equipment you will be using and how to use it
 * Build a thorough set of control variables (why are they important and what will you do about them?) - this investigation is not in a test tube so there is a lot to consider


 * Good luck!**
