Course Description: Introductory laboratory experiments.

This lab course is for 1 credit and typically meets for 345 minutes a week for 15 weeks plus meets for a 2-hr

midterm and 2-hour final examination. Students have significant daily reading to prepare for lab each day and

lab reports involving critical thinking and quantitative reasoning. Students are tested over the material via

quizzes and a comprehensive final exam. Students are expected to prepare prior to each lab (literature and

concepts), attend lab hours (conduct experiments via Zoom Online Labster Software), and report results (lab

reports). Students have required academic components and deliverables: written work (daily notebook, pre-lab

assessments, and lab reports). These activities, inclusive of the lab expectations and academic components,

average a minimum of 2 hours of work each week.

Number of Credit Hours: 1 semester hour. The grade is separate from the lecture grade.

Course Prerequisites and Co-requisites: Co-requisite: CHE 111. Lab fee required.

Course Objective: To provide students with an explanation of the basic principles of chemistry as illustrated through

laboratory experiments and to apply these principles to laboratory work involving critical thinking.

ACADEMIC INTEGRITY (A-9.1):

Academic integrity is a responsibility of all university faculty and students. Faculty members promote

academic integrity in multiple ways including instruction on the components of academic honesty, as well

as abiding by university policy on penalties for cheating and plagiarism.

Definition of Academic Dishonesty: Academic dishonesty includes both cheating and plagiarism.

Cheating includes but is not limited to (1) using or attempting to use unauthorized materials to aid in

achieving a better grade on a component of a class; (2) the falsification or invention of any information,

including citations, on an assigned exercise; and/or (3) helping or attempting to help another in an act of

cheating or plagiarism. Plagiarism is presenting the words or ideas of another person as if they were your

Definition of CRITICAL THINKING : disciplined thinking that is clear, rational, open-minded, and informed by evidence. http://dictionary.reference.com/browse/critical+thinking; (accessed May 23, 2013) Critical thinking involves the use of a group of interconnected skills. The skills needed can be broken down into six steps. Six Steps of CRITICAL THINKING

Knowledge means a student must have basic knowledge about the subject.
Comprehension requires understanding of the subject. Students that comprehend the new knowledge are able to relate the new knowledge to what they already know. Comprehending goes beyond simply parroting material back.
Application requires both knowledge and comprehension. Students must be able to carry out a task or apply their knowledge and comprehension to an assigned task.
Analysis involves breaking the knowledge down into smaller parts so it become clear how the smaller parts are related to other ideas.
Synthesis involves the ability to put together the parts you analyzed with other information to create something original
Evaluation occurs once we have understood and analyzed what is said or written and the reasons offered to support it. Then we can appraise this information in order to decide whether you can give or withhold belief, and whether or not to take a particular action. Adapted from: http://www.mhhe.com/socsicence/philosophy/reichenbach/m1_chap02studyguide.html (accessed May 23, 2013) Core Objective 2: Communication Skills: to include effective development, interpretation and expression of ideas through written, oral, and visual communication. COMMUNICATION SKILLS in the sciences For an excellent resource in scientific communication from a highly reputable source see the information provided on the Nature website link shown below. http://www.nature.com/scitable/topic/scientific-communication- 14121566 (accessed May 31.2013) Three especially informative links within the link shown above are:  Effective Communication  Effective Writing  Audience/Purpose Scientific communication traditionally includes writing in third person, past tense, passive voice. In formal, scientific writing slang terms and contractions are avoided. Core Object 3: Empirical and Quantitative Skills: to include the manipulation and analysis of numerical data or observable facts resulting in informed conclusions. EMPIRICAL AND QUANTITATIVE SKILLS Chemists rely on observations to explain the nature of the substances they study. There are two types of observations exist: qualitative and quantitative. A qualitative observation is an observation made with the senses and is usually expressed using words instead of numbers. Qualitative observations about a person sick in the hospital might include that the person is breathing rapidly, has a high temperature, and is very thin.

A quantitative observation is an observation that requires a numerical measurement and describes something in terms of "how much". The quantitative observation that a person has a temperature of 103.6 °F is much more useful information than just knowing that the person has a fever. Quantitative observations are preferred by scientists. Often quantitative data is acquired in lab. One or more measurement is always a part of any quantitative observation. A measurement determines the dimensions, capacity, quantity, or extent of something. The most common types of measurements made in chemical laboratories are those of mass, volume, length, temperature, pressure, and concentration. Measurements always consist of two parts: a number , which tells the amount of the quantity measured, and a unit , which tells the nature or kind of quantity measured. A measured number without a unit is meaningless. Once quantitative data is obtained, chemists then mathematically manipulate and analyze data. Adapted from saplinglearning.com; accessed May 31, 2013 Core Objective 4: Teamwork: to include the ability to consider different points of view and to work effectively with others to support a shared purpose or goal. Definition of TEAMWORK : work done by several associates with each doing a part but all subordinating personal prominence to the efficiency of the whole. http://www.merriam-webster.com/dictionary/teamwork (accessed May 23, 2013) TEAMWORK General Rules Each team member needs:  all ideas evaluated critically;  treat others in the group with respect  everyone needs to pull their weight, meet deadlines, and contribute equally;  actions need to be followed through;  reporting needs to be accurate and comprehensive;  problems with under-performing team members need to be discussed openly and resolved quickly; and  peer assessment should be given fairly

Every laboratory activity meets all 4 Core Objectives:

Core Objective 1:

Critical Thinking

Skills

Every lab will require a collection of data in which you must analyze the

information. Each lab has objectives that are achieved by manipulating

chemicals and equipment which involves inquiry skills.

Core Objective 2:

Communication

Skills

Communication with your lab partner is absolutely essential in order to

perform the experiment, take data, and analyze the results.

Core Objective 3:

Empirical and

Quantitative Skills

Each lab will include the manipulation and analysis of numerical data or

observable facts from which an informed conclusion will be drawn.

Core Objective 4:

Teamwork

When working with a partner in a lab setting, it is important to work as a

team, considering different points of view and working effectively to meet the

objectives set forth in the lab manual.

This Core Objective is Strongly Emphasized in Lab.
