Hello, my name is Mr. Calvin. This year, I will be taking your student down the road of enlightenment, through Life Science.

This blog is developed to help your student achieve success in my class and beyond and as a communications tool as well.  If for whatever the reason your student was absent, he/she can use this blog to research what was covered in class and not fall behind. It is the responsibility of the student to check the blog regularly for any materials they may need. Part of the preparation for higher learning is to gradually achieve greater independence through practice. What greater place than to start here.

The pages on this blog are updated as soon as an assignment or extra resource is added that can help the student with achieving the goal of independence. This blog is also a way of communicating with the parent or guardian any communications that our district may deliver occasionally. Parents/Guardians you are highly encouraged to view this blog along with your student to monitor their progress. Handouts that were provided in class will always be available in class or upon request.

Please feel free to offer any suggestions about how I can make this blog most effective and helpful to you and your student.

If you need any additional information, please feel free to contact me through email (Leonard.calvin@cobbk12.org).


This page will be used to post announcements from our school or from the district. To access Life Science please go to the top of the page and select the tab Life Science.

Available hours and video presentation. 

I teach two different subjects so please select the correct class for the specific times.

Per Governor, Cobb Schools will Remain Closed Through End of 2019-2020 School Year

We have been committed to keeping our community updated about the rapidly developing situation with COVID-19. Throughout the process, we have relied on guidance from the Georgia Department of Health, Centers for Disease Control and Prevention, as well as our state leaders.

In accordance with Governor Kemp’s guidance and to best prioritize student and staff safety, Cobb Schools will remain closed through the end of the 2019-2020 school year. Per executive order from Governor Kemp on April 1, 2020 all public schools and colleges in the state of Georgia will be closed for the remainder of the 2019-2020 school year.

School closures continue to include athletics/sports, extracurricular school activities, proms, school building activities, and trips.

While our school buildings are closed, the education process has not stopped. All staff are working remotely to best support students, including delivering digital and physical instructional resources to students while they’re at home.

We will continue to keep our community updated through this page as the most up-to-date source of information related to the coronavirus’s impact on Cobb Schools.

“We continue to make decisions based first on student and staff safety and in consultation with the Georgia Department of Health and the Governor’s office.” — Superintendent Chris Ragsdale

4-Day a Week Digital Learning Schedule

Beginning Monday, April 13, 2020, for all Cobb County students, and for the rest of the 2019-2020 school year, digital learning will occur on a Monday through Thursday schedule.

Good morning,

Unfortunately, MUST Ministries will be closed as well due to COVID-19.  Many families depend on MUST Ministries for support and resources.  Please put a note on your blogs letting families know that the food pantry at Acworth United Methodist Church will be open on Tuesdays from 1 to 5 pm to distribute food to needy families.  Additionally, Northwest Christian Church located in Acworth has a pantry that will provide food every Tuesday and Thursday from 9am to 12pm.

Please don’t hesitate to contact me if you need assistance or if you have a family in need.  If a family reaches out to you and they need assistance please give them my work cell phone 770-656-5061.


Thanks so much!

Greetings from your Barber bookkeeper! Regarding the Chattahoochee Tech field trip and $5.00 payments many students have already paid, we will wait for the district to inform us on how to move forward with possible refunds. As expected, CCSD leadership has a lot on their plate right now. I will let you know what I hear as time progresses. Thanks for your patience.

Coronavirus:  Information and Guidelines for Cobb County Schools  

The Superintendent and District Leadership have been maintaining close contact with public health officials and continue to follow their guidance on the health-related developments.  In an effort to keep our students, employees, and families safe, we remain committed to following the most current recommendations from the U.S. Centers for Disease and Prevention (CDC) and/or the Georgia Department of Public Health (DPH).  The following updates will be in effect immediately. 

Enrollment of New Students from Identified High-Risk Areas: 

Families attempting to enroll a student from areas with a Level 3 or 4 Travel Health Notice advisory for the coronavirus, as identified by the CDC and/or the US Department of State, should contact via telephone and/or email their local school for instructions related to registration.   

Re-entry of Students Traveling from Identified High-Risk Areas: 

Families should inform the local school via telephone and/or email if their student has traveled to areas with a Level 3 or 4 Travel Health Notice advisory for the coronavirus, as identified by the CDC or the US Department of State.  The local school will work with the family to determine the appropriate action regarding the re-entry of the child into school.   

Student Travel:              

Any school-sponsored and/or district-sponsored travel to areas with a Level 3 or 4 Travel Health Notice advisory for the coronavirus, as identified by the CDC or the US Department of State, will be canceled for the duration of the 19-20 school year.  Currently, travel scheduled within the US or for areas not identified as high risk will proceed as planned.  We have communicated with all travel companies utilized by the district to ensure they follow the same CDC and/or DPH recommendations. 

Re-entry of Employees Traveling from Identified High-Risk Areas: 

Employees should inform their supervisor via telephone and/or email, prior to returning to work, if they have traveled to areas with a Level 3 or 4 Travel Health Notice advisory for the coronavirus, as identified by the CDC or the US Department of State.   

You can learn more about the Department of Public Health’s guidance and what the Cobb County School District is doing here. The Department of Public Health will continue updating the community through its website, and the CDC is constantly updating their website with the most current information.  

The Cobb County School District will continue to follow the guidance from the CDC and/or DPH and will communicate updates to our employees and community.
