Introduction Last October 4‚ the group performed an activity that involved making our own yogurt. The group prepared the materials and followed the procedures to make the said yogurt. In the activity paper that was given‚ it dictated that during the yogurt making process‚ the bacteria underwent fermentation. “Fermentation

Adwoa Fosuah Bio Psych Lab Report 4 Cold Pressor Task Aim The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

defines that the pressure on a fluid is isotropic‚ meaning that the force/pressure in any direction applied on the liquid is the same in all directions. Hydrostatic Pressure Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the gravitational pull. The fluid is known as hydrostatic fluid. The pressure can be calculated from the control volume analysis of a small cube of fluid. It is known that pressure is force applied per unit area P = F/A‚ and the onlyforce acting

How to write a lab report Let’s take as an example a free-fall experiment. You drop a small steel ball from various heights and use an electronic timer to measure how long it takes the ball to hit the ground. From this you calculate the final speed of the ball using v = 2x/t. You believe that the ball will have a constant acceleration of “g‚” 9.8 m/s2. This will be seen if you graph velocity vs. time and get a straight line with a slope of 9.8. You end up with a table of data giving distances

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

HSC PHYSICS 2011 HSC PHYSICS 2011 PENDULUM MOTION BY NATHAN LOCKE Image taken from http://www.practicalphysics.org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which
