Welcome to Chemistry Lab at LUOA. This course is going to be a little different; it is going to be a hybrid of a virtual and a regular chemistry course. Laboratory is a very important component of any science class. The lab must be completed in conjunction with your regular science class. If you have a question regarding the lab, you have two options. You can message your instructor within the curriculum, or you can call into the LUOA office at 1866-418-8741 option 4 (teacher), option 3 (science). Science help is available from 8:30-5:00 Eastern Standard Time, Monday through Friday.

Important Things to Know 1. We pray for you. If you need prayer for anything specific let us know. We will add you and your need to our prayer list and will pray for you.  2. Labs are not optional. You must complete all of the labs found within a unit before the unit test may be attempted. Please do not ask us to allow you to “just take a zero.” It is one of our greatest desires to see you be successful and be prepared for all the plans that the Lord has prepared for you. This class is transcripted as a lab science; therefore, all labs must be completed. 3. The directions and the supplies may differ in this manual from those in lesson. ALWAYS FOLLOW THOSE IN THIS LAB MANUAL. Please refer to this document often; a hard copy can be very helpful. 4. The Messaging System is an easy way to contact your teacher, if you have questions about the labs or your classwork in general. Please remember to be respectful. Use Mr. or Mrs. when you send your message. Watch your spelling and capitalization (you are not texting friends; this is school).

2

5. Teachers have 24 hours to respond to your messages, and 24 – 48 hours to grade your submissions. This does NOT include the weekends. 6. The curriculum will permit uploads of a wide variety of formats (.csv, .docs, .pdf, .xls, .xlsx, .docx, .jpeg, .jpg, .ppt, .pptx, .txt, and .rtf). Uploads in MS Word (.docs or .docsx) are preferred, and in some cases, may be required. Word documents enable the teachers to give comments along with scoring and are more universally accepted than some other formats. 7. Repeatedly submitting blank assignments or disregarding teacher comments may lead to your science progress being blocked until the work is completed satisfactorily.

Virtual Labs Chemistry labs are to be completed using a virtual program called Late Nite Labs. You

will sign on to the Late Nite Labs (LNL) site and complete your labs there. Your sign-in information will be included.. The names of the Late Nite Labs and the curriculum labs will NOT match exactly, that is okay. Next to the assignment, you will see what the lab is called “in the curriculum” (your regular LUOA lesson) and what it is called “in LNL” (Late Nite Labs). You will complete it in LNL and the grade will go into the curriculum to be averaged in with your regular coursework. In your planner, you will see the assignment due, when you open it up, you will see a teacher’s note telling you to go to Late Nite Labs and complete a specific lab. At that point go to LNL, complete the LNL return to the lesson, and submit it as complete. This will alert the teacher to go to LNL and grade the lab. You will not be allowed to complete the unit until all labs are complete.

Course Expectations In this course, there are certain expectations. We want you to be aware of these expectations from the very beginning. Please read the following guidelines and follow them when submitting your assignments. Understand that while some of these guidelines may apply to all of your work (Headings & Complete Sentence Answers for instance), others only are needed with certain assignments (Science Reports & Science Lab Reports for example).

Questions must be answered in complete sentences. What is meant by complete sentences?  When speaking of answers, complete sentences do not mean only grammatically complete. It also means to use part of the question in the answer.  Q: What color are your eyes? A: My eyes are blue.  Q: Which planet is nicknamed the “red planet”? A: The planet nicknamed the red planet is Mars.

Unit 1 Measurement and Analysis Assignment: 3. Report Metric System. (In curriculum) Introduction

When you started this class, your advisor asked you to email all of your teachers and introduce yourself. Please do so as an attachment to this assignment. Also include your contact information (email and phone number please) as well as a statement that you have read and have accessed this science lab manual.
