The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely

Experiment 1 Laboratory Techniques and Measurements Purpose: To determine measurements of different items that vary from solids to liquids and be able convert those values to other SI units of measurement. Procedure: I used a variety of scientific tools such as; a ruler‚ beaker‚ graduated cylinder‚ volumetric flask‚ thermometer‚ burner‚ and digital scale to find unknown values of measurements for each of the indicated

on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚ then they will regenerate stronger and faster. This is important because it could lead to faster regeneration for the animal and lead to bigger things such as finding a way to incorporate this to human regeneration. Many experiments have been researched

Human Demography: The study of age-structured populations Lab Preparation: Read the lab and be on time. There will be a quiz. Also‚ we’ll be riding a bus to the field location. If you want to join us for lab‚ don’t miss the bus! Bring your lab manual‚ a hard notebook or clipboard‚ paper and charcoal (for rubbings) and wear warm‚ possibly waterproof clothes. We’ll be outside for a good portion of the lab regardless of the weather. Background: Demography Demography is the descriptive study

I. Objective The first objective of the measurement of thermal conductivity & one-dimensional heat conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between

SCIENCE EXPERIMENT REPORT AIM : To show the percentage of oxygen in air. HYPOTHESIS : The percentage of oxygen in air is about 20%. APPARATUS AND MATERIALS : Glass trough‚ gas jar stand‚ metre ruler‚ candle‚ marker pen‚ matches‚ plasticine. Figure 1 VARIABLE : i. kept constant : the size of the candle ii. manipulated : the amount of oxygen inside the gas jar iii. responds : the level of water in the gas jar PROCEDURES : 1. Use some plasticine to fix a

“Cell Transport Lab” Hypothesis: I hypothesis that there will be a movement of molecules out of the egg‚ and will move into the water solution. Osmosis will occur within the egg‚ and in the process the molecules of the egg will diffuse. Time (hrs) | Observations | Circumference (cm) | * 0 | * Egg is of normal weight and size * No membrane is being shown‚ and is almost perfect | * 14 centimeters | * 24 | * Egg has gotten larger taking in some of the water * Shell is soft

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect

and the volume of base needed to react with the acid is measured throughout. By using those data‚ the students are able to find what they were trying to calculate. On this lab‚ the students found the unknown acid‚ 4.36 x 10-5‚ and the equivalence point of 8.4‚ as well as the value of pH. Purpose: The purpose of the experiment was to utilize the techniques of titrations to measure the concentration of an acid or base in solution‚ to calculate molar mass of an unknown acid or base‚ and to determine
