Based on the knowledge I gained from the blubber lab‚ I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment‚ the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore‚ blubber is a method of homeostasis‚ because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s
