Background Research What is it? Why do we have it? � Observations/prior NECESSARY How do you do it? � Google Scholar knowledge for hypotheses are

Water Drops on a Penny BR surface tension, chemical structure of water, covalent bond, hydrogen bonds, polar solvent, non-polar solvent, hydrophobic, hydrophilic.

Trash Bag Test BR Force Flex ratings Hefty ratings Great Value ratings What effects the strength of a trash bag? � How are trash bags made? Different materials based on trash bag

How Music Effects Heart Rate What do you think would have been some important background research to conduct to have made a good hypothesis?

Conflicting Research Music affects heart rate Scientific American Music induces a continuous, dynamic—and to some extent predictable—change in the cardiovascular system, " said Luciano Bernardi, a professor of medicine at the University of Pavia in Italy Emotion and chills create changes in cardiovascular system Potential therapies for stroke and other conditions Music does not affect heart rate Experiment rejects the hypothesis that relaxing music calms you down and upbeat music gets you excited Could not prove that music had an effect on heart rate or blood pressure Emotional response to blood pressure changes the effect � Do they like the genre of music? Based experiment off of statistics – no significant differences found

Research is essential to the process! You must conduct research to know the basis of your experiment and to form an EDUCATED guess – your hypothesis!

Exit Ticket Exit tickets will be my daily way of seeing whether or not you have understood the objectives we have gone over during class each day. They will NOT be graded for accuracy but WILL be graded for completion so make sure you always try each and every question. These exit tickets must be done silently and independently. If you violate this, you will lose your participation points for the day. You must wait to begin your exit ticket until Ms. Kemal says to begin.
