We have been studying the organization of the elements in the Periodic Table. The elements are arranged in Groups and Periods according to their physical and chemical properties (the periodicity of certain properties). These properties include atomic radii, ionic radii, ionization energy, electronegativity, and electron affinity. We added these properties to a copy of the Periodic Table which will be referenced for future class work.
HW: Students were provided a handout regarding the element groups and their properties. Using this handout, color code the Periodic Table for the nine groups. The elements included in a particular group should be shaded with a chosen color. On the back of the sheet, create a legend using the chosen colors, the group name, and a brief description of the group.

Limitations of the Gas Laws
As part of our review, we need to recap and summarize the nature of gases and the kinetic-molecular theory of gases (KMT). Based upon the postulates of the KMT and the results of experiments with gases, the Gas Laws were developed - Boyle's Law, Gay-Lussac's Law, Charles' Law, Avogadro's Law, and Dalton's Law. From these laws, a powerful equation is derived: PV = nRT.
The concepts concerning gases are discussed in chapter 13 of the textbook.
HW: Using the textbook, summarize the six physical properties of gases; summarize the six postulates of the KMT; define the term postulate (pgs 417-423 of the textbook). Also, explain the limitations of the ideal gas law (pgs 444-445).

Crushed Can Demo - That was crazy!
We completed the quiz for Unit 2 today! Tomorrow, we will be discussing the crushed can demonstration. Please complete a journal entry in which you attempt to explain your observations. Also, bring your journals to class tomorrow. I will be collecting them.
HW: Complete a journal entry for the crushed can demonstration - (1) draw an illustration of the demonstration, (2) write a short procedure, (3) describe your observations, and (4) write a conclusion and draw particle diagrams to explain.

Formal Lab Report
I am happy to observe that the mass and volume concepts seem to be well understood by students. Tomorrow, we will focus on preparing for Thursday's very short quiz.
HW: The formal lab report for the Mass and Volume Lab is due tomorrow. All parts of the lab must be typed, not hand-written.

Mass and Volume Worksheet
We are discussing the techniques to compare densities of various substances using particle diagrams and graphs. Be sure that you are comfortable comparing the different particles diagrams and graphs on the worksheet.
HW: Complete the worksheet - pages 3 and 4 (challenge questions are optional, but recommended). Continue to work on your formal lab reports.

Plants and Currents
Life Science
We are working on the plant unit in class and growing plants at home. Students are to read pages 289-296 in the book, complete writing/defining the bold sentences and words found in the reading and answering questions 1-3 on page 296. I will be checking the 3rd column on the project as well as the gymnosperm color page (worked on during class today).
Earth Science
Students are to review their notes on ocean currents in preparation for a quiz on Tuesday next week. Bring all questions to class tomorrow.

Science Fair Success!!!
Life Science
The 2nd Annual TPA/TPJA Science Fair was a HUGE SUCCESS! Congratulations to all of the 6th and 7th grade participants!
Earth Science
We are continuing our exploration of the Earth's oceans. Research an explorer who traveled across a vast ocean and compile the following information: name of explorer(s), year, route of the voyage, purpose of the trip, type (and name, if available) of vessel, instruments and/or maps used for navigation, and any other interesting information. Be sure to write out the information that you find on a separate sheet of paper to be submitted as evidence of your homework on Monday.
