Today in class:
Some students indicated they did not remember how to do the vocabulary cards. Here is a link to how to do them How to make vocabulary cards.
7th grade: In all 7th grade classes today we went over the diagram of a microscope and I pointed out the parts on a class scope. Students were reminded that their TIPS homework, Cellebration is due tomorrow (Friday) and that their vocabulary words are due on Monday. All classes were reminded that failure to do their homework assignments will carry the consequence of book work, while other students engage in the microscope lab.

8th grade classes: Today all 8th grade classes began going into depth about the parts of an atom and how to use the periodic table to determine the numbers of protons, electrons and neutrons in any given element. I started off by explaining how the elements are identified on the periodic table. Students had many questions about why certain elements are named certain ways and at this point, there is a great deal of confusion. FEAR NOT! All will be made clear.
I pointed out that there are three basic SUB ATOMIC particles that make up an atom; the PROTON- a large particle found in the nucleus with a + charge. The NEUTRON- a large particle found in the nucleus of the atom and it has ~~ charge (neutral). And the ELECTRON- a particle about 1,000 time smaller than a proton that ORBITS the nucleus of the atom and has a - negative charge.
The ATOMIC NUMBER is how the periodic table is ordered and it goes from the smallest known atoms (Hydrogen being number 1), to the largest atom at number 118. The atomic number is also the number of protons found in any atom of the element you are looking at. Since ALL atoms are neutral (they have no charge) there has to be an equal number of electrons to balance out the number of protons. Therefore in element number 89 (89+ protons) there must also be 89 (- negative electrons) orbiting the nucleus. This is true for every element on the table. We used this information to work on the TIPS in class.
If you know the atomic number it is easy to figure out how many NEUTRONS are in the nucleus. Simply find the mass number of the element (It will be larger than the atomic number). Now subtract the atomic number from the mass number (using only the whole number part. (You can't have a fraction of a particle.)
Homework reminder! ALL TIPS ARE DUE TOMORROW (7th and 8th grade) All vocabulary cards are due on Monday!
All students were given a science fair/ research project parent letter to take home. All science classes at Dunnellon Middle School, are engaging in a research project. Students will decide on their own topic, develop their own hypothesis and experiment and conduct their own research over the next 10 weeks. While we will spend one or two days on developing an abstract and checking their progress this project will be conducted wholly on the student's own time. Students can come in early in the morning before classes begin or stay after when school is out OR they can choose to come to class during lunch and use the class computers for research. A project proposal form and example was sent home and is due back to the class on November 1st, 2013 Students
