The Nature of Matter (starting chapter 2)

NOTE: This post is for Thursday and Friday because on Friday we are running a Wednesday schedule.

Today students collected data from their pea experiments. Some of the peas have started to germinate! After collecting the data and talking about the feasibility of collecting data everyday, we moved on to start chapter 2: The Nature of Matter.

Students were given a guided notes sheet to help organize their notes. We watched a short video clip on carbon dating. Click here to see it.

Homework:

Watch the video clip below and use the information to complete the table in your notes packet that compares ionic and covalent bonding.



After watching the video, finish reading section 2-1 in your book to complete the questions on Van der Waals forces etc. You also need to finish the check-in questions for homework. You should use all of section 2-1 (pages 35-39) in your book to help you review.

This is due on Monday.

F Block Lab Data

On Monday, each student will need to turn in the following information:

1. A table with the class averages for Hot, Cold and Room Temperature bubble height in cm (from part A)

2. A table with the class average for Acid, Base and Neutral bubble height in cm (from part B).

3. A well written paragraph, with complete sentences, which includes three sources of error for the experiment and three ways to improve the experiment.

If you are unsure about what to include for your sources of error you can read this article.

Below is the data for you to analyze. You can click on the picture to make it larger.

Lab Data for G block

On Monday, each student will need to turn in the following information:

1. A table with the class averages for Hot, Cold and Room Temperature bubble height in cm (from part A)

2. A table with the class average for Acid, Base and Neutral bubble height in cm (from part B).

3. A well written paragraph, with complete sentences, which includes three sources of error for the experiment and three ways to improve the experiment.

Enzymes

What do they do? Where are they found? Today we learned about how enzymes work. Later this week we will be doing our first QUANTITATIVE lab and as such, spent a bit of time today going over the procedure.

Homework:

Read the "Potato Catalase Lab" post below. In your lab notebooks, finish writing part B of the procedure and answer the prelab questions. This is due for your next lab period.

pH and intro to carbon

We started class today with a reading quiz on 2-2. Students then did a quick lab activity where they needed to determine the pH of eight unknown substances.

The last 15 minutes of class were spent starting section 2-3. Students were given a guided notes sheet.
Homework for tonight: (due the next time your class meets) Read the rest of section 2-3 and take notes. YOU WILL HAVE A READING QUIZ.

On Friday a summary report (1 per group) is due. The summary report can be any of the following:

Make a Venn diagram and fill in the names or draw pictures of the items that were in each of the solutions in the correct section in the diagram and write the properties in the correct section. (See example below.)

Write a brief report about acids, bases, and neutrals in paragraph form and include examples from the testing lab.

Draw a concept map or word web comparing and contrasting acids and bases and add descriptive words and examples. (See example below.)

Create a narrative poem, song, or story about the acid, base and neutral solutions and describe their properties.

Your summary report must also include the answers to the following questions:
1. What is the pH of human blood?
2. What is the pH of stomach acid?
3. What are antacids and how do they work?

Bonus point opportunity: If you find the actual pH's of all 8 substances, you can earn a bonus on your summary report.

Reviewing Tests & Starting Chapter 2

Today we spent about 20 minutes reviewing the first test of the year. Afterwards we moved on to chapter 2: The Nature of Matter.

From now on I will do my best to have guided notes sheets for students to use in class. Hopefully this will help students to have more organized notes and enable them to study more effectively.

We watched this clip comparing ionic and covalent bonding.

We also watched a clip from the Discovery channel on Kennewick Man and the role that radioactive carbon dating played in discovering the age of this mysterious man.

Homework: Read section 2-2 (pages 40-43). Take notes that include the key concepts and vocabulary. You will have a reading quiz tomorrow.

Format of the test: There are 50 multiple choice questions and 1 essay. The multiple choice questions are each worth 2 points. The essay is worth 25 points and will be considered a separate test which will you complete AT HOME using the honor system. There will be three essays and you will complete 1 of them. You will only have 30 minutes from the time you open the questions until the time you must stop.

Why is the essay being tested this way?

1. You will likely have tests like this in college.
2. We don’t have enough class periods.

HEADS UP FOR THE ESSAY: All answers must be in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement your essay but are not sufficient on their own. Read the question thoroughly before you begin to write. You may hand write or type the essay.
