Recap:
We hit the ground running for the second nine weeks with a new seating chart to change up working in class. I spent a few minutes reviewing the rules and responsibilities of the class and school and then we dove right in at all three grade levels. In 6th grade students were introduced to atoms and molecules and the differences between them. I pointed out that atoms are the building blocks of EVERYTHING and are much smaller than cells, which are the building blocks of LIVING things. Atoms are the smallest particle you can have of any element on the periodic table and if you go sub-atomic, you no longer have an atom. At the sub- atomic level we have protons and neutrons found in the nucleus of the atom, and electrons orbiting the nucleus in the electron cloud. Protons have a + charge and Neutrons are NEUTRAL. Both these particles are roughly the same ass. Electrons on the other hand, are tiny (1/1837th the mass) of an individual proton or neutron. Examples of atoms could be O (oxygen), Au (gold), or N (nitrogen). While atoms are the smallest unit of an element you can have they do vary in size becoming larger as you move down the periodic table.
Molecules, on the other hand, are 2 or more atoms joined together chemically. They are composed of atoms and scientists look at them two ways; with the chemical formula CO2 and the chemical structure. O=C=O. The forumal tells us the number of atoms in the molecule. 1 carbon atom, and 2 oxygen atoms, while the structure shows us how they look and how they will bond and interact with other things. There is a special type of molecule called a macromolecule and these are very large. As an example, we used glucose- C6H12O6 with a structure of :
In 7th grade we started talking about the organelles within the cell. We spoke about undifferentiated cells called STEM cells and watched a brief video of cellular division forming a blastocyst
We just started into the structure of the cellular membrane when the bell rang.
In 8th grade
Brain bender:
Professor Quantum was in the far north gathering evidence on climatic changes caused by the "greenhouse effect". Quantum relayed his findings to the nearest base by shortwave radio. During one radio conversation, Quantum reported the temperature as minus 40 degrees. "Is that Celcius or Fahrenheit?"responded the radiomam. "I couldn't care less which way you record it."replied Quantum. Why would professor quantum have such a cavalier attitude to scientific data?

6th Grade Class Information and Syllabus
Weather and Atmosphere:
Unit Essential Question: How do the relationships among the five spheres affect life on Earth
How do the relationships among the five spheres affect life on Earth?
Key Learning Statement: The atmosphere is layered and within these layers are weather patterns that affect life and are caused by interactions among spheres. Water is constantly being recycled through the spheres. Heat transfer affects the development of weather.
