Week of Jan. 29 – Feb. 2 “Magnets”

This week in Physical Science we will continue in our 4th unit of the year “Electricity & Magnetism”. Our focus for this week is Magnets. 

Students will get a chance to explore through a variety of activities demonstrates how magnets and magnetic fields work or are created.

 


*Students are required to complete all notes at home as well as CK-12 Practice through their Edmodo accounts to allow time to explore in class using labs and virtual labs every week. Please notify an 8th-grade science teacher if your student needs to stay after school or before school to complete online assignments. All teachers are flexible and willing to assists any student with whatever the needs may be to get assignments completed on time. No excuses!

  • Online Assignments for this week through Edmodo for All Science Classes: CK-12 Science Practice (Magnets).

Standard(s)/Objective(s): S8P5. Obtain, evaluate, and communicate information about gravity, electricity, and magnetism as major forces acting in nature.

a. Construct an argument using evidence to support the claim that fields (i.e., magnetic fields, gravitational fields, and electric fields) exist between objects exerting forces on each other even when the objects are not in contact.

Driving Question: How do the properties of magnets explain why some materials are magnetic or some are not?

WEATHER ALERT & ONLINE LEARNING DAY(S)

All Cobb County Schools are closed on Wednesday, January 17 & Thursday, January 18, for both students and staff, due to road and travel conditions.

Students, please see Edmodo for our online learning day(s). Students should continue finishing up their notes for Electric Circuits and Electric Currrents as they will be assessed up returning. Rest and Enjoy the day(s) off while continuing learning at home.

Don’t forget to continue working on the CK-12 Science Practice: Cirucuit and Currents (2 new assignments).

Welcome Back! “3rd Nine Weeks Begins!”

We hope everyone has thoroughly enjoyed their Christmas/New Years Break. It is now time to get back to work. Report Cards for 2nd Nine Weeks will be distributed to go home on Friday, January 5th, 2018. Please be sure to check your student’s grades and see where they stand. Please be reminded that all 8th grade Science teachers host Wednesday Morning tutoring sessions weekly @ 8 am. Please get your child plugged into the Science Madness as well as Saturday Tutoring. Many students that attend have expressed their appreciation for this extra day of study and many have benefited from it. Don’t miss out on this great free opportunity. Please stop by the front office see Dr. Hargrett to sign up.

Christmas Break is Upon Us!

As we prepare to end the 2nd Nine Weeks on a good note, please make sure that your child is studying nightly. All students are required to take the Midterm exams scheduled for December 19th and 20th (Early Release Days). If your student will be out on those days, please be sure to schedule a time to take the assessment upon return in January by end of the 1st full week.

Happy Holidays to All!!! See you January 4th, 2018!

Weeks of Dec. 4 – 8 & 11 – 15 “Energy: Heat Transfer”

This week in Physical Science we will continue with our focus on Energy by looking at the 3 Methods of Heat Transfer (Conduction, Convection, & Radiation).  

As we bring our Energy unit to an end, please make sure your child is studying nightly. These last two weeks, we will be covering the 3 methods of Heat Transfer.

Energy and Energy Transformations Exam … 

On December 14th, 2017, students will be assessed over concepts taught in the energy unit. Please see Edmodo for any updates and or resources that can be used to prepare for this assessment.

Happy Studying!

Please notify teacher if your student needs to stay after school or before school to complete online assignments. All teachers are flexible and willing to assists any student with whatever the needs may be to get assignments completed on time. No excuses!

Standard(s)/Objective(s): S8P2.  Obtain, evaluate, and communicate information about the law of conservation of energy to develop arguments that energy can transform from one form to another within a system.

a. Analyze and interpret data to create graphical displays that illustrate the relationships of kinetic energy to mass and speed, and potential energy to mass and height of an object.

b. Plan and carry out an investigation to explain the transformation between kinetic and potential energy within a system (e.g., roller coasters, pendulums, rubber bands, etc.).

c. Construct an argument to support a claim about the type of energy transformations within a system [e.g., lighting a match (light to heat), turning on a light (electrical to light)].

d. Plan and carry out investigations on the effects of heat transfer on molecular motion as it relates to the collision of atoms (conduction), through space (radiation), or in currents in a liquid or a gas (convection).
