Physics Lab Report Statement of the Problem: The problem that was arisen in Problem #5: Motion up an Incline was in reference to a change in acceleration in both an uphill and downhill motion. The question on hand was whether or not the acceleration was the same going uphill as it was downhill or different from each other in both directions. To obtain a secure conclusion this experiment required the use of a frictionless cart, an inclined ramp, motion sensor, meter stick, and assistance of computer
Biology Lab Report Lab No. 18: Biochemical Genetics: Smooth Peas Wrinkled Peas Data Presentation: The diagram of cotyledon for smooth and wrinkled pea is attached to the next page. The table of starch presents is below: Type of Pea Starch Present? (Color change) Smooth Yes (Dark blue) Wrinkled No (No change) Conclusion Smooth pea is dominant than wrinkled one, hence we can say the letter of allele which controls this characteristics is S. ‘SS’ and ‘Ss’ for smooth
Cellular Respiration Lab Report I.Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There

Lab Report The Effects of Drugs on Cardiac Physiology The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside
Lab Report Comparing Oxygen Consumption Rates in Different Mammalian Subclasses The purpose in experimenting with computer simulations was to compare oxygen consumption rates in different mammalian subclasses. We compared monotremes, marsupials, and placental mammals at both warm and cold temperatures. The results supported our hypothesis that when temperature increased, metabolic rate decreased. This was also supported using a student's t-test. We also found that placental mammals had the
and inaccurate measurements of many substances. However, our results did not differ that much from the actual value and phase 2 went very successfully because we found the amount of NaOH needed to standardize the acid. Overall, I would consider this lab a success because we found the molarity, the amount of moles, the pKa, the ka, the equivalence points, and the molecular weight that did not differ that much from maleic acid. Maybe next time, we could make sure none of our equipment were contaminated
What is a lab report? One of the most critical, yet ignore aspects in scientific fields is proper scientific writing. Here, the student’s ability to accurately communicate research findings is important for their academic performance in the biological and physical sciences. Science is a generally communal field, where researchers develop ideas and look for ways to communicate and convince others in the scientific community of the validity of those ideas. As such, learning how to communicate your
In the candle lab we saw a lot of things that happened. Before the candle was set on fire we made some observations about the candle. The candle was white and the wick was also white. At the time the candle didn’t have a smell. As we touched the candle before it was lit it felt smooth and the wick felt like a rope- like item. The wick hole was small. As we were observing the candle before it was lit the state of the candle was soild state. When the candle was lit we noticed that the flame was moving
hypothesis is accurate because it proved that enzyme lactase is specifically hydrolyzed lactose. The test tube containing milk and lactase is the only one that contained glucose; the others containing sucrose and lactase did not.

prominent. Record readings on the report sheet. Have your instructor check and initial your report sheet for your first buret reading (sample #1, only). 6. Rinse a clean 125 ml Erlenmeyer flask with deionized water. Deliver approximately 20 ml of unknown acid into the Erlenmeyer flask. The tip of the buret should be approximately 1/2 inch below the top of the flask to avoid loss due to splashing. 7. Add 2 or 3 drop of phenolphthalein indicator. (Above your lab bench). 8. Titrate the unknown acid
Purpose: Writing is important in all areas of scientific work, because results have no value unless shared with other workers. A lab report explains what was done in the experiment, what was learned, and what the results meant. An important aspect of science is to present information in a clear and precise manner so that other people can interpret and trust your data. Consequently, experimental data should be organized and presented in scientifically accepted ways, the most common forms being tables
The lab begins with reflux of the reaction to form an ester followed by several extractions from an organic layer. To purify the ester the compound is dried by gravity filtration with a drying agent, distilled using simple distillation, and recrystallized. The aldol condensation is reacted in a test tube and the solute is collected via vacuum filtration and recrystallized. The esterification procedure was performed first. To begin the lab, the heating mantle was set at the 6 setting, and the hot
Introduction Force-length curves offer insight into how muscles function. Muscles are made up of fascicles, which are bundles of muscle fibers. Muscle fibers are allowed to shorten during a contraction when myosin moves past actin in sarcomeres. The length of the sarcomeres affects the number of action-myosin cross-bridges, therefore affecting the force output of the muscle. When a sarcomere is very short, the myosin cannot move (as it essentially hits a brick wall), so force output is very low
Introduction The purpose of this lab was to study the response of the genus Daphnia to chemical stimuli and to examine human responses to different stimuli. A stimulus is an incentive; it is the cause of a physical response. Stimuli can have a physical or chemical change; an example of a physical change is a change in temperature and sound. An example of chemical change would be changes in hormone levels and pH levels. Muscular activity or glandular secretions are responses that occurs when stimulus
Purpose: This lab gives the idea about the enzyme. We will do two different experiments. Enzyme is a protein that made of strings of amino acids and it is helping to produce chemical reactions in the quickest way. In the first experiment, we are testing water, sucrose solution, salt solution, and hydrogen peroxide to see which can increase the bubbles. So we can understand that enzyme producing chemical reactions in the speed. In the second experiment, we are using temperature of room, boiling water
Photonics Lab Introduction In the world of communication, lasers can be very helpful in transporting a variety of information across the planet. In this experiment, we decided to advance our knowledge about lasers and perform more tedious activities with them. Instead of shooting lasers through a gelatin substance and reading angles in which they reflect, we were going to step it up a bit. This time our final goal was to be able to verbally communicate through space using a laser. Photonics is
In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types
ABSTRACT This report explains enzymes and how their activity can change depending on different factors. We explored this by breaking the experiment into two parts; in the first half we measured peroxidase activity at the different given temperatures and the second half we repeated this but let it sit at room temperature before measuring in the spectrophotometer again. The results showed that temperature does affect the ability of peroxidase. The effects were not reversible. (Enzyme Lab Handout) INTRODUCTION
