LARN 021 C6D1
Start the following in class:
1. The required journal topics for today, J21, are:
a. What is the difference between a physical change and a chemical change?
b. Contrast the range of proportions of substances that can be incorporated into a mixture to the range of proportions of substances that can be incorporated into a compound.
c. Contrast the change in the energy when a coarse mixture is produced to the expected change in the energy when substances react to form a compound.
d. Contrast how the properties of a coarse mixture differ from the properties of substances that make it up, and also contrast how the properties of the compound differ from the properties of the elements that reacted to produce it.
e. Contrast the ways a mixture might be separated into its components to the ways a compound might be separated.
2. Do all the pages in the chapter 2 Section Review packet as a formative assessment to find out some of the...

Start the following in class:
1.. Return to your class notes on the classification of matter OR to the web site at http://chemwiki.ucdavis.edu/Analytical_Chemistry/Qualitative_Analysis/Classification_of_Matter and reflect on the meanings of the terms substance, mixture, suspension, colloid, and solution.
Reflect on what has been explained and this time write out your responses to the following seven questions as journal reflection entry J20:
All matter is either made of substances or mixtures of substances.
a. There are two different types of substance. What are the two different types of substance and how are they different?
b. There are three different types of mixture. What are they and how do they differ?
c. How can suspensions be separated?
d. How can solutions be separated?
e. What are colloids?
f. What is the approximate range of particle sizes necessary to produce a colloid?
g. Why do the above mentioned particle sizes not result in solutions nor in suspensions?
2. a. Construct a Frayer word map for the word "formula unit". Refer to https://drive.google.com/open?id=0B9ft9hAr_RjiMm8xUWljMU0tWjQ for more information as to what...
LARN 019 C5D3
Start the following in class:
1.a. Go to https://socratic.org/chemistry to research the topics brought up in section 2.3 and 2.4 of your text, OR use the PQ5R or SQ5R method to prepare a study guide for section 2.3 and 2.4, pages 48 through 57, in your chemistry text. As you read, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. Or, if it will save you time, write a question for the section, read the section for the main idea and write a summary paragraph when you are done reading. You may record vocabulary entries in the body of your study guide ,or you may check them off on the chapter 2 vocabulary list that is available on Google Drive > Student Resources > Vocabulary. As you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.
1.b. Then ask yourself the Section Assessment questions...
