Graphs and Density

Today in 2nd period and 4th period, we started with a do now assignment on the concepts of precision, accuracy, and sig figs. We went over problems from SOL Practice #1 and then took some notes on graphing. Today we did a lab involving water displacement, where we measured mass and volume for rubber stoppers. Students can use this mass and volume data to calculate the density of the stoppers.

The homework for today is the following:

Period 2 (Adv Chem):
Answer Questions 11-18 in SOL Practice #1, which can be found here.

Period 4 (Hon Chem):
Answer Questions 1-18 in SOL Practice #2, which can be found here.

Accuracy and Precision

Today in 2nd period and 4th period, we talked about the definition of accuracy and precision. The information that was presented in class today was from the packet found here. We also talked about the concept of significant figures, and I taught the Atlantic & Pacific Rule. We stopped at #20 in the packet.

The homework for today is the following:

AP Chem:
Read Chapter 3, sections 3.1 through 3.3. Do the following problems at the end of the chapter: 5, 13, 15, 19a, 21c, 29, 31, 33, 35, 37c, 43, 45

Period 2 (Adv Chem):
Answer Questions 1-10 in SOL Practice #1, which can be found here.

Period 4 (Hon Chem):
Answer Questions 1-18 in SOL Practice #1, which can be found here.

TGIF!

AP Chem
I have posted the answers to the Chapter 1 & 2 Practice Test here.
You will also see a document entitled "Polyatomic Ions You Should Know."
E-mail me if you need additional practice problems or if you have any questions about Monday's Test on Chapter 1 & 2.

Advanced Chem
Today we wrapped up the lab experiment with the colored liquids. We discussed the fact that a graduated cylinder is more precise than a beaker because it has smaller markings/divisions on it. On Monday we will go over the results of the math assessment, and you will learn about precision and accuracy.

Honors Chem
Today we wrapped up the lab experiment with the colored liquids. We discussed the fact that a graduated cylinder is more precise than a beaker because it has smaller markings/divisions on it. I have posted the packet on precision and accuracy here. Your homework was to do the following problems in this packet: 3, 4, and 5, and the graph on the last page. On Monday we will go over the results of the math assessment, and you will learn about precision, accuracy, and significant figures.

Colorful Chemistry



Here is a summary of today's activities in Period 2 (Adv. Chem.) and Period 4 (Hon. Chem.).

I collected the signed syllabus sheets, and then students took a lab safety quiz.  Today's lab experiment was on the density of colored liquids. Watch the YouTube video above.

Tonight's homework is to write a detailed procedure for determining the density of a liquid. Be specific! Be clear! Write your procedure in a way that someone could be able to follow your instructions.  Students took a math assessment today, which should help me determine what they can do and what I will need to teach. Math skills are definitely important in chemistry! Thanks to everyone for a great day. I look forward to seeing everyone tomorrow (Friday!)

Okay, Let's Get Started

Thanks to everyone for a great first day. I really enjoyed meeting everyone, and I'll do my best to learn all your names. Here's a summary of important information for each class:


AP Chem
Read Chapters 1 & 2 in your textbook and the Ch. 1 & 2 Review Guides. Get the syllabus sheet (with e-mail information) filled out and signed by you and your parents. Look over the Safety Contract and be ready for a quick, easy quiz on lab safety. Complete the Ch. 1 & 2 Practice Test. On Friday we will go over the practice test and you'll probably get a Ch. 3 Review Guide. Test on Chapters 1 & 2 on Monday!

Advanced Chem
Get the syllabus sheet (with e-mail information) filled out and signed by you and your parents. Look over the Safety Contract, and be ready for a quick, easy quiz on lab safety. Study the packet entitled "Math Concepts Used in Chemistry," and be ready for a math assessment to help me determine your math readiness.

Honors Chem

School Starts Tomorrow

My schedule for the 1st semester is as follows:

1A = AP Chem
1B = planning
2AB = Adv Chem
3AB = planning
4AB = Hon Chem

I'm looking forward to meeting you. I hope you're prepared to work hard and give me your best effort.
Try to be an active learner. If you have questions, please ask! Make sure that you communicate with me so that I can help you if I can. I hope you have a great school year.
