Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

- 3 zipper lock bags - Miscellaneous items (tape‚ marker‚ label) - 1 sterile cotton swab METHOD: 1. Prior to placing any food products into the petri dish‚ categorize them into the control (agar plate containing no food products) and the experimental (agar plates containing food products) via labelling. 2. Leave petri dishes inverted for a time period of 48 hours as to provide a clear illustration as to the absence of microbes and forms of contamination on the agar surface. 3. Before

Success of Dugesia tigrina regeneration in different water temperatures Abstract: The experiment at hand aimed to determine if the species Duguesia tigrina has an optimal temperature for regeneration. The experiment used three different spring water treatments of different temperatures. The treatments included a cool 12° treatment‚ a room temperature 25° treatment‚ and a warm 30° treatment. Each of the D. tigrina were cut in half‚ and each half was placed into a designated section of a water treatment

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

doses of Vitamin B complex; 2) 10 minutes of meditation; and 3) 15 minutes of aerobic exercise. Each suggestive treatment is complete with a reasonable physiological rationale. I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling from New York City to Los Angles

The first is figure out if concentration plays a part in the reaction rate. To begin this trial‚ we gathered 3 cuvettes in which we added horseradish peroxidase in the following amounts; .5 mL‚ 1.0 mL and 2.0 mL. In each of these cuvettes‚ we added 2.0 mL of H2O2‚ 1.0 mL of Guaiacol and enough pH 5 Buffer to fill each cuvette to 8.0 mL with all of the materials

In this experiment we are going to describe stress and prove how can a prolonged exposition to it have a negative impact on memory. The definition of stress used in this experiment is: difficulty one suffers that causes worry‚ emotional tension or loss of concentration. The reason why this topic has been chosen is because stress is a part of nowadays‚ hectic society and it has a very noticeable effect on people’s performance‚ in either work or daily life. The outcome of this experiment could be

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in
