Fundamentals for Chemistry-Quantitative Measurements

Data Tables and Observation: Fill out the data sheet (below) for the experiment and submit with this form. Recording data carefully

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

Servicing the phototherapy lamp involves placing the Bili-Meter about 25cm away from the lamp to measure the irradiance.

When your lab report is complete, submit this document to your instructor in your assignment box.

Remove foam plug from the inoculate flask and pour it into a cuvette. Incubate it at 37°C and the optical density readings at 600nm every 10-15 mins. Pour into the

Then is to place the test tubes in front of a beaker full of water so that it is not direct light, and turn on the lamp. Then is to record the data every 5 minutes for 20

In high school, we did this same exact lab when we were covering convex and concave lens. I remember my teacher first asking questions about the content then we would do the lab and afterwards we would answer lab questions and discuss our results. Therefore, my high school teacher and this teacher did the labs the same, except my teacher would teach most of the content before the lab.

Summary of lab procedure – what YOUR GROUP did, include KEY observations – be concise! Someone should be able to repeat your experiment from this summary alone.

The next section, experimental methodology, describes how the experiment was setup, carried out, and the conditions in which the experiment took place. Section 3 displays the results that were obtained from the experimental procedure, as well as provides a brief description as how the data were evaluated. Section 4 attempts to create a logical interpretation as to what the results mean, as well as identify any potential errors that may have skewed the results. Finally, section 5 summarizes the report, and suggests conclusions for the results posed throughout the experiment and potential solutions to errors discussed in section 4.

Please read this experiment carefully so when you come to the lab you understand some of the basic ideas of an oscilloscope. Become familiar with the documentation for this experiment and the location of the various buttons and knobs on the oscilloscope.

This experiment is important because the experiment can conclude the interaction between light and mediums with different temperatures. The experiment can be use to see how energy within the system affecting incoming photons within the system. The experiment is being conducted because the researcher thought that the ideas of light interaction with mediums would be important. This was because light is very common in society with the help of electricity and to understand how light interact with mediums around could help us understand light.

14. Take readings for Lux, Humidity and Temperature (In this investigation, readings were taking by putting the sensor up through the lip of the bucket). In future trials attempt to match them to these readings. It is more efficient to do all trials on the same day to make sure of the same humidity and temperature.

Aim: To investigate if changing temperature will effect the concentration of NaOCI- in the bleach inside Janola.

This lab is made up of four different parts. In the first part we will examine the effects of a light ray reflecting at different angles of incident from a convex, flat, and convex mirror. In the second part a light ray will be refracted through a rhombus prism at different angles of incidence. We will measure the angles using a protractor. For the third experiment we will examine the indices of colors as light is refracted through the rhombus. Lastly, we will use polar lens to examine Brewster’s angle and polarization.
