We will discuss the topic of understanding populations in terms of its main properties that scientists tend to measure as they work with populations, compare the three general patterns of population dispersion, identify the measurements that are used to describe changing populations, and discuss the three general types of survivorship curves.
Henry’s Law and Solubility-Temperature Relationships
Students will analyze the relationships among solubilities of several substances as functions of their temperatures. Furthermore, students will reinforce and apply Henry’s law in terms of the solubility of a gas in a liquid as it relates to the pressure of the gas above that liquid.

Section 14.3: Factors Affecting Solvation
We will briefly review the types of mixtures and focus upon the factors that influence the solvation process. Students will distinguish between saturated and unsaturated solutions. Students will write the general rule to determine if solvation will occur that is based upon certain factors that must be known about the components of the substances. Furthermore, students will elaborate upon the solubility state as well as express it in units of measurement. Moreover, students will understand and apply Henry’s Law in the solubility of a gas that is related to the pressure in a given volume.

Tuesday, May 29, 2012: Test on Chapter 18: Introduction to Ecology
Students will be evaluated upon the interdependence process between and among organisms and their environment with a focus on the energy transfer process through food webs as well as how the nutrients get recycled through the biogeochemical cycles of nature.

Chapter 18 Review
We will answer and correct the concept map along with the brief assessment that we did yesterday and answer the scheduled homework assignment question #’s: 6, 14, 15, 17, 19, 20, and 23 on page 376. Furthermore, we will answer question #’s: 1 through 8 and the short response on page 377.
NOTE THAT WE WILL BE HAVING A CHAPTER 18 TEST ON TUESDAY, MAY 29, 2012 UPON THE STUDENTS RETURN FROM THE FOUR-DAY WEEKEND.

Sec.14.1: Types of Mixtures
We will complete answering the reading guide on sec.14.1 together since the remaining of it was homework. We will reinforce this topic by examining the properties of mixtures and provide further examples.
If time permits, students will be evaluated upon their comprehension skills on this subject matter through a question and answer study guide.

Review Sec.18.4 Study Guide and Do a Concept Map
We will go over the study guide on the biogeochemical cycles and complete a concept map that is based upon the given clues. When students are done they may continue their work on the chapter review questions on pages 376-377. They are to do question #’s: 6, 14, 15, 17, 19, 20, and 23 on page 376. Furthermore, they are to do question #’s: 1 through 8 and the short response on page 377.

Chapter 14: Mixtures & Solutions, Sec.14.1: Types of Mixtures
Students are to work on their reading comprehension skills that are based upon types of mixtures by defining the four given terms, compare and contrast soluble with insoluble mixtures as well as miscible and immiscible liquids. Furthermore they are to identify three properties of a suspension as well as a colloid and be able to give three examples of each. Moreover, students will elaborate upon the Brownian motion and decipher the type of solution that is based upon its given property.

Sec.18.4: Biogeochemical Cycles
We will briefly review the classwork on energy transfer from Friday, and begin the class discussion upon the biogeochemical cycles, namely, the water cycle, the carbon-oxygen cycle, the nitrogen cycle, and the phosphorus cycle, whereby a group of four students will comment about each selected cycle individually within the assigned group and report out to the class when called upon after a period of time.
