Think Like a Proton --- Stay Positive

8th Grade Science

In 8th grade science, students have been learning all about atoms. Students have learned strategies to help them figure out how many subatomic particles exist within one atom of a particular element. This strategy is known as the APE MAN Strategy. Atomic # = Protons = Electrons and Mass – Atomic # = Neutrons.


It is now time for us to move on to the Periodic Table. In the upcoming week, students will learn about the "Groups and Periods" on the Periodic Table, and how these numbers relate to the structure of atoms. Students will also learn about the reactivity of atoms. In the future students will be moving on to counting atoms within chemical formulas.

IP&C Science Classes

In IP&C, students have blazed quite a path. Students in this class have revisited the states of matter and applied the transfer of energy through state changes. Students have refreshed their knowledge on atomic structure and how valence electrons determine an atoms reactivity and placement on the Periodic Table. After learning Periodic Table Trends, students learned about "Cations and Anions" and how they lose or gain electrons to form bonds. From the information they have learned they dove into Ionic bonding using the Lewis Dot structures. Since students have mastered Ionic bonding we are now moving into Covalent Bonding. The Question is To Bond or Not To Bond?

Biology

In biology, we have explored Replication, Transcription, Translation and where these occur inside the cell. More specifically, which organelles are involved in these processes. We have discovered that replication means that DNA makes more DNA. Transcription on the other hand, is where DNA makes RNA. While translation is when RNA makes protein.


Students have also identified the difference in cell organelles between plant and animal cells, by examining different cell examples under the microscope.

Chemistry

In chemistry, students have taken a journey through matter this past 6 weeks. Students have refreshed their knowledge on chemical and physical properties of matter. In class we have learned that physical properties break down into Intensive and Extensive properties. Students have also learned about mixtures, pure substances, and states of matter. Reading the Phase Diagram is a walk in the park for our chemistry kiddos now. After we mastered this information, we moved on to the Periodic Table where we learned about Periodic Table Families and Periodic Table Trends, such as, electronegativity and ionization energy. We are currently working on Atomic Theory projects and I can not wait to see the results.
