Methods And Analysis

Again, label 7 1.5ml tubes 0 thru 6. Place 15μl of each serially diluted extract into its corresponding labeled tube. Next add 465μl of media into each tube. Then 60μl of Alamar blue in each tube. Finally add an additional 60μl of cells (adjusted to 10,000 cells/20 μl). Vortex each tube for 5 seconds. Now, take 3 different samples 190μl samples of concentration 0 and put it in Wells A2, B2, and C2. Repeat this step again by taking 3 more different 190μl samples of concentration 1 and putting it in wells A3, B3, C3. It should be noted that it is important to vortex each 1.5μl tube again be-fore putting it into the 96 well plate. Contin-ue this same procedure consecutively for the re-maining concentrations.

The materials needed for this experiment included test tubes, a test tube holder, the unknown compound #202, 35mL beakers, gloves, safety goggles, ethanol (to clean equipment), stirrer (to mix solutions), the 15 possible compounds that are provided, pH strips, distilled water, wooden splints, spatula to get out unknown compound #202, waste bucket, Bunsen burner, graduated cylinder, 500mL beaker for the waste, plastic dishes to measure out compound and the scale.

Materials & Procedures: The supplies and equipment you will need are a pipet, daphnia, caffeine, petri dish, and a stereoscope.

The 20ml beaker was washed with dichloromethane to collect the solid left in the beaker. The filtered solution was collected in the 25ml filter flask. Then, the filtered solution was transferred to a clean centrifuge tube and the solid compound was transferred to a clean test

Mineralogical composition for the bulk samples powder were determined using X-ray diffraction (Philips X-ray diffraction equipment model PW/171) with monochromator, Cu k -á radiation (1.542 =גÅ) at 40 kV and 35 mA at X-ray diffraction lab, Physics Department, Assiut Faculty of Science, Egypt. The patterns were recorded from 4 to 90°2è. In addition, reflection peaks were between 4 and 902Ѳ, of 0.06◦/min speed. Corresponding spacing (d,Å) and the relative intensities (I/I°) were also obtained [Moore and Reynolds,1997].

The discussion topic this week is to apply the scientific method to daily life. According to our reading, to apply the scientific method is to: observe, hypothesize, experiment, collect and analyze data, and communicate (Ireland, 2012., p.26). A scenario that strikes me, is when an iPhone shuts off before reaching one percent. As a person that has had nothing but iPhones I have experienced a few times. In order to fix this, we can apply the scientific method. The first step is to observe the problem at hand; Why is my phone dying before reaching one percent. Next is to create a hypothesis; How do I get the phone to one percent? After creating a hypothesis, we then experiment with the solutions. The goal is to get the phone to one percent, in order to do that it is important to run the phone until is dies. If it dies before reaching one percent, you are to lug the phone in until it comes back on. After coming back on, run the phone until it dies again; if

The materials used in this lab were water,a petri dish, matches, a 150mL beaker, one candle. a graduated cylinder and a ruler.

Measurement and analysis defines measurement objectives, identify specific measures to meet those objectives and determines how those measurements will be performed. They also collect and store data, implement those measurement activities, and communicate the results to line and project management (Walsh, Jairath, Paterson & Grandjean, 2010). An effective evaluation tool is vital when measuring the clinical performance of undergraduate nursing students. Also, accurately assessing the critical competencies required to demonstrate in the clinical setting is a neccessity of the evaluation tool. For example, it is important that the evaluation tool be clear, concise,and adaptable to a comprehensive diversity of clinical experiences and faculty

Good laboratory practices follows, checking the equipment and familiarising yourself with all the components that you will use in your experiment. We undertook this by following ‘figure 4’ in the laboratory manual.

There were multiple materials used during the experiment. A blender, banana, markers, spectrophotometer cuvettes, 10 mi. test tube/rack, 50 ml beakers, and a 5 ml pipette. The solutions used during the experiment

In this section we introduce the empirical models we use and the primary results. This study is designed based on the Difference-in-Difference (DD) approach, in order to eliminate the impact of confounding factors that affect all monitors before or after the subway opening. We first develop a basic DD model using distance as specification, and the new subway lines to the control group monitors that are located further than 15 km.

A methodological framework was necessary to organise the project in a systematic and rigorous way however this methodological framework must be underpinned by a conceptual framework (Denscombe, 2010), which represents my preferred approach to this inquiry. This framework supposes that firstly, metacognition holds lifelong value for the pupils and will improve their enjoyment and achievement. And secondly, that my teaching can be improved by more inclusion of metacognitive strategies and provide a more enjoyable experience within the lab when compared to the ‘traditional’ scheme of work used at the school.

This paper will discuss the method of research to be used, the respondents of the study, the sampling technique, the instrument to be used, the validation of the instrument, the administration of the instrument and the statistical treatment of the data that will be gathered.

The materials and methodology was followed as per the guidelines given in the lab manual(Ajlouni,2015).
