As we prepare for our first major science test of the year, our classes will be going through sample PAT questions and how to answer them. These type of questions tend to be heavy in source analysis (reading graphs, tables, or scenarios) and then discerning key information. For the environmental chemistry unit, there are sample problems below to help with revision. Additionally, we will be going through tables and diagram analysis in RTI after lunch this week. There are sample diagrams and tables in the presentation below for students to access as they aim to interpret data and increase their knowledge in this skill based area.

Key DatesCamp Easter Seals: Thursday October 25 (Leaving at 8:00 am - Returning at 3:30 pm Science Test (Environmental Chemistry): Tuesday, Oct 30. Monday InfoFor the math stations that we will be working through this week, please find attached the information. As a reminder, for approximately 30 minutes, your group will work through 1 station. At the end of that 30 minutes the assignment will become homework and will be marked the next day in class. Ech group will also have a station where they work directly with Mr. Gordon to address any questions or concerns surrounding algebra and equations.
The Balance ScaleLast week we finished off our first unit in mathematics, Rational Numbers. As of now, the exam marks have been made visible in PowerSchool. Parents, I would encourage you to ask your son or daughter about the test and students I would ask that you share your outcomes with your parents. This week we will be looking at solving equations.. Check back as we move forward in this unit for notes and assignments. During our outdoor school week, we are gathering data from waterbodies in the area to do a comparison study and then create a lab report.
At this point, we have visited Nose Creek and Panorama Hills Creek and will be going to Vivo Pond on Thursday. After taking our last water samples, we will write a conclusion and hand in our data. We will be following up the lab week with a full written report based on class driven questions. We are also coming towards the end of our science unit and will be wrapping it up next week before writing a test next week. This week we have been working on the Coventry River Assignment as a way to introduce several key ideas and topics to our classes. Our key take aways include: -In terms of OVERALL WATER QUALITY, Dissolved Oxygen (D.O.) is our key indicator. A D.O. of 8-10 ppm (mg/L) is an appropriate level to support a high amount of aquatic life (a high biodiversity). -Phosphates, usually added from fertilizers and animal waste runoff, cause ALGAL BLOOM. Algal Bloom is a process where Algae rapidly grows, decomposes, and causes heating of water, less sunlight to reach lower into the water and as a result less plant growth and lower oxygen levels. -The sewage treatment , comprised of 3-4 stages, depending on the municipality, removes most waste and dissolved materials. Some amounts of plastics, medications, phosphates, nitrates, and other material can pass through the system which then has an impact on water systems. That said, runoff from communities, farms, and golf courses tend to be worse for a water system as there is little materials removed and little natural filtration before materials enter the water system. -Bioindicator species that thrive in high oxygen environments tend to be the best bioindicator species because they are almost non-existent in low oxygen environments. On October 15, 16, and 18 we will be doing a water and ecology study in our community which will test our practical application and understanding of these concepts in a real world setting.
As we continue with independent learning this week, please go through the following modules for review of rational numbers on Khan Academy. Review the following modules from Khan Academy. Be sure to complete the practice problems that follow the video.
Your Key Terms table is due at the end of class tomorrow.
