Course Materials Under Revision for 2017-2018

Laboratory Requirements and Equipment

LAB REQUIREMENTS FOR THIS COURSE HAVE CHANGED. LAB WORK IS REQUIRED FOR COURSE CREDIT AT ANY LEVEL — LABS ARE NOT OPTIONAL.

Honors students must complete all of the safety and skills labs and at least 8 numbered labs to receive course credit.

AP students must complete all of the safety and skills labs and at least 15 numbered labs to receive course credit.

All labs for credit must be completed by the close of the school year in June, unless you make special arrangements with the instructor.

Lab assignments will be available from the web site at the start of the year. Most labs will be associated with specific topics, and you are encouraged to complete the lab and send in the report during during the assignment period. You make make arrangements to complete the other labs out of sequence if you have trouble obtaining equipment.

IMPORTANT! For safety reasons, both you and your parents must read the safety procedures before starting the lab sequence. Your parents must sign and send a copy of the lab permission letter to me before I can accept any lab reports from you for credit.

Lab Equipment

AP Students

If you are doing the labs for AP Credit, you should have specific equipment and chemicals to perform lab work at a college level. I highly recommend the CK01A Chemistry kit listed at The Home Scientist, LLC, which includes all the equipment and chemicals required for the AP Labs in the Illustrated Guide to Home Chemistry Experiments, except for a good lab gram scale, which you will need to purchase separately.


Honors Students

If you are doing labs for Honors Credit, you may be able to complete labwork with somewhat less expense by acquiring those chemicals and materials needed for your specific labs. In addition to the equipment listed below, many labs will use common household items, such as paper, pens, rulers, cups or jars, food samples, cleaning solutions, plastic bags, etc. These will be listed in the equipment section of the individual labs.


The Home Chemistry Lab: Minimum Requirements

This equipment list includes standard chemistry lab equipment for a minimal home chemistry lab that should allow you to complete at least one alternative form each lab; we will also be using more generally available household items for many of the labs. If you cannot afford the Chemistry Kit listed above from the Home Scientist, you may be able to complete sufficient labs for Honors credit with the equipment listed below. Note that many pieces have perfectly adequate substitutes in items you probably have in your house already. You will need to calibrate appropriately all substitute equipment. You may use any convenient units so long as you are consistent and willing to do the math to convert to SI (metric) units when necessary. When substituting household items for standard equipment, make certain that the substitute meets safety requirements: glass should be used instead of plastic, to avoid problems with acids or solvents, and any container used for heating should be rated to withstand the heat.

Lab equipment may be borrowed from schools or purchased. Sometimes local college bookstores or medical schools carry dissection kits; staining kits and other supplies are often available from educational toy stores and science museums.
