Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

takes (if at all) for the iodine to remain its orange-yellow color.2 Hypothesis Enzymes must be kept at certain conditions to function at its optimum level. Indeed‚ factors that may cause the enzyme to denature are: pH‚ temperature‚ and salt concentrations. When an enzyme is denatured‚ it can no longer bind to the active site‚ and therefore cannot carry out its functions. Therefore‚ adding pH buffer to amylase will affect the enzyme’s function upon its addition to starch‚ which can be indicated

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

hydroxylamine. We were able to measure enzymatic activity by the change in absorbance per second with a spectrophotometer. By testing different concentrations of peroxidase and its reaction rate in seconds‚ we were able to see that as the amount of enzyme increased the catalytic reaction also increased. The optimal amount of peroxidase concentration to be used in the subsequent experiments was determined to be 1.0 mL. Any amount above this would have caused the rate of absorbance to be too fast

of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from the freezing
