The first few weeks of Earth Science has been all about how we use maps to understand the Earth as a whole. We learned about the different types of maps that exist, and how they show us different features of the Earth. We started the unit by mapping the school, and Ms. Zafiris tried to use the maps to get around her new school.  

          

We then explored latitude and longitude, practicing interpreting the coordinates for different points on the Earth.



Finally, we looked at topography maps. Taking a 3D landscape and putting it on a 2D map can be hard to comprehend, so we made physical topography maps using modeling clay and water (dyed blue to represent the ocean) and as our "sea level" rose, we drew contour line to map the landscape. This illustrated how the steeper a landscape is (either going up, or down into a valley!) the closer contour lines are, helping us to visualize and read topography maps. 

And of course, you can't do science without reflecting on your experience, so we wrote up our observations and conclusions. 

If you want to look at the topography of where you live, you can go to TopoQuest and check out your landscape. It might surprise you what it looks like from a bird's eye view!

11/13 This week the 6th graders continued their exploration of natural resources in science class. After completing their energy project, we took a deeper dive into different sources of renewable energy. Biomass and nuclear energy are types that have a lot of potential, that scientists are still learning a lot about. Imagine being able to turn on a light bulb from energy from animal waste! Or being able to harness nuclear energy and travel through space- not a reality yet, but we saw the enormous energy potential by watching a video of solar flares. Next week we will do the always classic lab on cleaning up an oil spill. Announcements: Please arrive at school before 7:55 AM. Parents - please fill out Pick Up patrol every morning, even if your child will not be attending school that day. As part of initiatives to keep our students well, we ask that snacks and lunches contain minimal sugar.

While the nation awaits election results, the sixth graders at HCA have a decision! In homeroom, they held a mock election and Joe Biden emerged as the winner. Lord Voldemort (a fictional character from Harry Potter) came in at a close second.  Ms. Zafiris's math class is hard at work tackling the division of fractions. Our sixth grade will soon be undertaking their very first science fair projects. For some inspiration, the students explored last year's projects. Soon they will propose their own research topics. Stay tuned to learn more about their investigations.  November 6, 2020 Parents - please fill out Pick Up patrol every morning, even if your child will not be attending school that day. As part of initiatives to keep our students well, we ask that snacks and lunches contain minimal sugar.  Students may not bring SODA to school.  The STEAM Lab is cold.  Students are encouraged to have HCA sweatshirt or blazers over their uniforms on STEAM days.  New ...

From robots to Greek myths, our sixth graders are enjoying the wide array of subjects that middle school has to offer! In STEAM class, the students are working in rotations to explore robotics and control technology as well as scientific data and analysis. Arrington, Sophia, and Summer experiment with Ozobot. Sam and John use Scratch to code a knight animation. Izabella and Gabby use Google Earth to create maps of significant landmarks in Philadelphia.  As they work through each challenge, the students record their reflections in their online journals. In language arts class, the sixth grade is using D'Aulaires Book of Greek Myths to study figures from Greek mythology. This will give them background knowledge that they'll need in their next unit to tackle literature with many allusions to these Greek myths.  The sixth grade is studying the technique of continuous contour in art class. Mrs. Mueller challenged the students to draw their hands without once picking up their penc...
