Mrs. Arras - Science
We are off to a great start so far! Below you will find a brief description of the content that we will cover this year. This will be updated every month with an overview of what we're currently learning. For a more detailed description of what we've done every day in class, as well as any homework that's been assigned, please click on the tab called "calendar." There will be separate entries each school day for 8th and 7th graders.
I hope you will find this website a useful resource. Please feel free to contact me via email with questions, concerns or ideas on how to make this resource more useful. Also, if you are interested in volunteering in the classroom, please email me!
7th Integrated Science
This year students will study erosion and deposition, plate tectonics, ecology, and chemistry. The units will be tied together through the theme of the Pacific Northwest, and the crosscutting concepts of energy and matter, and cause and effect. (For more on the new standards and crosscutting concepts, please visit the NGSS tab.) We are starting the year with our erosion and depsosition unit.
Our overall guiding questions for the year are:
- How do energy and matter flow in the Pacific Northwest? (Crosscutting Concept #5: Energy & Matter: Flows, Cycles & Conservation)
- How do organisms and Earth processes affect one another in the Pacific Northwest? (Crosscutting Concept #2: Cause and Effect)
FEBRUARY UPDATE: We are almost half of the way through out ecology unit! We will take our first quiz, which covers activities #72 - 77 in the beginning of this month. We also got the trout eggs from the Oregon Department of Fish and Wildlife out of the tank for the first time to make observations. Additionally, we will be having a couple of different guest teachers who will be talking to us about stream health, and the affect of agriculture on the environment. We will also take a field trip to Whitaker Ponds in March to practice assessing stream health.
8th Grade Integrated Science
This year students will be studying integrated science. We will start with space, and will learn about physics, waves, evolution, and genetics as the year progresses. We will be looking for connections between our units using the crosscutting concepts of stability and change, and scale, proportion, and quantity. For our space units, we will focus on:
- How does the regular motion of the earth, moon and sun cause predictable changes on earth? (Crosscutting Concept: Stability and Change)
- How can we use models to understand the day/night cycle, the reason for the seasons, and the lunar cycle? (Crosscutting Concept: Scale, Proportion and Quantity)
FEBRUARY UPDATE: We are halfway through our genetics unit! In this unit, we will learn about Mendelian genetics, the use of Punnett's squares to predict traits in offspring, as well as the differences between sexual and asexual reproduction. We've been adding in some other more recent developments in the field of genetics as well, such as epigenetics and CRISPR.
