Spectroscopy Of Atoms Lab Essay

1826 words - 8 pages

Introduction
This evaluation plan describes the procedures that will be used to evaluate the Spectroscopy of Atoms lab and its addition to the General Chemistry 1 course. This course is an entry-level chemistry course for those interested in natural sciences, pre-medicine, and engineering. Currently, there are no non-major chemistry options available, so this course fulfills a need for science requirements in the college. The background of the module, the purposes of the evaluation, the intended decisions and questions, the proposed methods and instrumentation, the selected sample and inherent limitations, logistics and timeline, and the budget for the evaluation are included in this ...view middle of the document...

This lab will replace one covering the conservation of mass, and replaces it with spectroscopy, a topic not previously explained in other activities. Previous semester evaluations and data suggest that student scores and understanding should increase with the addition of this new lab.

Summary of the lab:
The student will use a spectroscope to look at Helium and Hydrogen emission lines. The helium calibrates the spectrometer, and the hydrogen compares experimental vales to the ordinal values. A colored solution (dye mixed with unknown chemicals) is dropped on glow in the dark paper (which is then absorbed). The students expose the solution-saturated paper to light, and specific colors will glow because of the way light behaves as a particle and a wave.

The course lectures clarify concepts from the textbook and teach students problem solving skills. Homework assignments and pre-lab questions are submitted online. Students are required to purchase a key for the online homework software. Doctoral faculty members that specialize in Chemical education teach the course.

Purpose
The purpose of this evaluation is to collect timely and accurate data for use by the decision makers in the general chemistry division related to the implementation of a new lab in future semesters of the general chemistry 1 course. The strategies implemented in planning this lab include the fact that it should be reliable, inexpensive, safe, and easy to implement. This is a summative evaluation used to assess the effectiveness of the new lab within the general chemistry course.

Sub-purposes:
• To collect information from the target audience, student enrollees, regarding applicability and effectiveness.
• To collect information from experts in the area of chemistry regarding the appropriateness and functionality of the newly instituted lab activity.

Primary Audience and Stakeholders
The director of undergraduate chemistry, Dr. H, the lab manager, Ms. B, graduate teaching assistants, and the students are the primary stakeholders. Relevant secondary stakeholders include the supporting faculty for this course and coordinators of the other lab courses offered to undergraduates.

The designer and implanters of this evaluation is JoAnn DeSalvatore, a student in TLT 476 Assessment of Instructional Technology, with the guidance of Dr. Amankwatia, the course instructor.

Decisions and Questions
The client to inform major decisions regarding the implementation of this lab will use this evaluation.
These are the assumed decisions:
• Is this a lab that should be used in future semesters?
• It is applicable and appropriate to students enrolled in general chemistry?

Student decisions:
• Did they perceive that they have learned more or new information because of this additional lab?
• Pre and post test questions
• Did they enjoy doing the new lab?
• It is relevant for current major or future career path.

Expert decisions:
• What is their...

What´s Atomic Emission Spectroscopy? Essay

1233 words - 5 pages Atomic Emission spectroscopy is a technique used in the determination and quantification of elements present with a chosen sample. The basic idea of this process it that first an atom is formed, and then it is excited then emitted. After the photon is emitted and energy is released knowing the energy released one can quantitatively and qualitatively determine the wavelength present and hence the concentration of the element. Inductively

By using Bohr’s postulates, chemists were able to determine

In atomic absorption spectroscopy, the sample is decomposed into atoms by a source of heat, such as a flame. The flame not only atomizes the sample, but also gets rid of the solvent used to dissolve the compound so we can analyze only the desired atoms. The concentration of atoms in the vapor is measured by the absorption of characteristic wavelengths of
