Unit test for inequalities will be on Tuesday, May 29. Need extra practice? I've attached a practice sheet to this blog post. Skip question #1. Inequality review questions start at question number 10.
Monday is our field trip to Camp Horizon. Please be at school by 8am, as the bus leave at 8:30 with or without you! Come prepared! Bring a hat, sunscreen, bug spray (if you want) and water. It's about an hour's bus ride away.
See you Monday!!!

Students worked on a couple of virtual labs to experiment testing different variables on electrochemical cells. This lab was handed in today. Here is the website and lab sheets in case you missed it.
What is an electrochemical cell?
Modifying an electrochemical cell
In math, we moved on in our linear inequalities and focused on adding and subtracting inequalities. Notes attached...
Students wrote their unit test in circle geometry today. All math tests are marked in class immediately after writing them. This gives students instant feedback, and a chance to learn from their mistakes. Please ask your child how they did on the test, where they went wrong, and what they can improve on. Tomorrow we start a new math unit: Linear Inequalities. This is a follow up to the Linear Equations unit that students traditionally meet with some challenges. It is one of the more important math concepts when getting ready for high school math.
Students: If you are not yet part of our class on Khan Academy, please join with the class code: NUFQAGU3
I have sent out some assignments (practice) in these math areas.
We discussed electrical safety today. Remember that AMPS are more important than VOLTS when considering how much damage electricity can inflict. Students were then given a full class period to work on problems in circle geometry including asking the teacher questions, creating a cheat sheet for the test, and catching up on missed work. A reminder that the unit test for circle geometry is this Monday, May 14.
We covered a lot of heavy math today so please REVIEW the 3 new properties of angles in a circle! (notes attached at bottom of this post)
1. Central and Inscribed Angle Property: the degree of a central angle will always be double the degree of an inscribed angle, as long as they are subtended by the same arc.
2. Inscribed Angles Property: all inscribed angles that are subtended by the same arc will be congruent.
3. Angles in a Semicircle Property: all angles that are subtended by a semi-circle will have a 90 degree angle.
We will spend some time tomorrow and Thursday reviewing these concepts, practicing with questions, and creating a foldable (if you wish) for your UNIT TEST ON MONDAY.
Review: find the missing angles:
Tomorrow we will be writing our practice PAT. This gives you an idea of what will be expected when you write the actual PAT. You will be given a writing prompt for your essay, and a concept to write a business letter on. We will start the exam at 9:00 and write for the morning. We will be using official PAT times, meaning that all students will be given until 11:00 to write the exam. This means we WILL be sitting in class until 11:00 no matter what. We will be writing through nutrition break. Please bring a quiet reading book to occupy yourself should you finish early. NO PHONES WILL BE TOLERATED DURING THIS TEST WRITING TIME. Phones will be confiscated.
ALL students are allowed double time if they need it, as well as an ADDITIONAL 30 minutes after that, so if you need to write until 1:30, this time will be given to you. Students will be moved to Mr Lafferty's class after 11:00.
Tomorrow is also Food Truck day! Grade 9's will be taken down to the trucks from 11:40-12:40. Bring your "truck bucks" or cash. One truck buck = $1. In order to speed up the process, choose your items before hand and bring exact change.
In math, we had a mini assessment on tangent lines and circles. Many students did great, and many others were lost. I can not repeat it enough times- you need to be reviewing your material in all subjects *every day* in order to make sure you know what you are doing, and to help you to remember things. We try to make it as easy as possible to review things by posting just about everything we do on our blogs. Here is the assessment question that we worked on today. I have also attached the notes from today on chord properties in a circle. Please review the 3 chord properties so you can move on tomorrow in math.
In science, we started our final unit- electrical principals and technologies. We will start this unit by learning about static and current electricity. Interested? You should conduct some RESEARCH on your own! (Remember, this is part of the Read, Review, and Research thing that we talked about- you should be doing at least the first 2 EVERY DAY!) We watched a Bill Nye video on static electricity and answered some questions.
