This week we started a new unit in Science, Mechanical Systems. We touched briefly on this unit when we were doing our Grade 8 Mobile Escape Rooms. This week we reviewed Simple Machines and have started to cover the concept of Work and Mechanical Advantage.
On Tuesday there will be a quiz on Linear Relations. Students are expected to be able to complete a table of values, graph using 4 quadrants, derive a formula from table of values and be able to write expressions using word problems. I have attached some of the word problems we worked on this week in class.
All students who are away for Band Camp on Tuesday and Wednesday will be making up the Quiz Thursday at Lunch and will be allowed to also continue during the flex period. Bring your lunch.
Some extra practice for anyone who would like to study some more over the weekend.
Students are working on various Light and Optics Topics. Students will have class time this week to both work on the presentations and present. I have attached all topics below in case anyone needs it.
We have continued with some new topics in Light and Optics. This has included colour, the wave model of light and revisiting the Electromagnetic Spectrum.
For the wave model of light students are expected to now both what a wavelength is, and parts of a wave including crest, trough, rest point, amplitude as well as what frequency is and how to calculate frequency.
We also revisited the Electromagnetic Spectrum. Among learning the different types of waves that exist we also discussed how Gamma Rays hold an incredible amount of energy and that they are not green as we cannot see them and being inundated by a massive amount Gamma Rays would not lead us to becoming The Hulk but rather becoming The Not Alive.
Finally students were given some time to explore white light, prisms and laser pointers. They were all able to show how white light is indeed composed of all the colours of the rainbow. Laser pointers were used to reflect and making some laser mazes with mirrors.
Students exploring various light properties.
Our best demonstration of white light being a combination of all the colours of the rainbow.
We will be moving onto Linear Relations next week on Tuesday. A reminder that Monday we will be having a final Linear Relations Quiz. Students will need to know Distributive Property, combining like terms and solving equations that have variables on both sides.
Picking up from before the break on Linear Equations we did a review on Monday and yesterday we went over a new concept. Having variables on both sides of an equation. This concept requires students to use all the skills they have learned so far in this unit including: opposite operations, 2 step equations, distributive property and combining like terms.
Some practice that we have been doing in class are below. The first set is what we have been working on. The second set is more challenging and some students will be ready to do those today. There will be a final quiz (Linear Equations Quiz III) early next week.
In Science we covered the topic of Colour in terms of Light and Optics. we also watched . short video of National Geographic's Brain Games: In Living Colour. We finished off with a lab. We have 2 quick topics to go in this unit: Wave Model of Light and Optics Technology. There will be a short quiz next week.
In Math we are wrapping up our unit on Data Analysis and Probability. Data Analysis had a focus on misleading graphs and students completed an assignment at the end of that chapter. Probability is what we have worked on for the last week and a half. We started by playing some games to test out experimental probability and whether a game was fair or not. Students have now moved on to working out probability of two or more events. Both theoretically and experimentally. Attached below is the key to the Probability Review that was handed out today.
The answer to 4 is c and the answer to 5 is a. 6 is a simple tree diagram that should have 9 outcomes in total.
The answer to 11 is: Green.
Vocabulary students should know includes:
Apologies for not updating the blog much in January. Students completed the Body Systems Project. Students did a great job on the visuals, the presentation and the doctor's panel. Students also displayed some great collaboration with their group members in order to be successful.
To finish off the unit students researched and presented the History of Public Health and presented one major era in the history of time. There were some great presentations with the themes of sanitation, pathogen/antibiotic relationship and vaccines being prominent.
we wrapped the unit up with a heart rate activity and students learned about resting heart rate and active heart rate. How to find your heart rate and what heart rate is optimal during exercise and how heart rates change for highly trained athletes.
Students who have not handed in the current events assignment due before winter break can see below for both the assignment and the article.
In Math we did a quick review of Ratios, Rates and Proportional Reasoning from before the break. This was followed by introducing the unit project on what our class would look like if it was a specific country. Students will research statistics of the country f their choice and then use their proportional reasoning skills to see how the class would be represented if it was a country. Some good websites to research sites include:
In Science, today we began our Human Body Systems Project. It is a big group project which will involve an oral presentations, a life size body systems gallery, a doctors panel and a quiz. Students have the rest of the week to work on the project and we will be ding various activities and presentations next week.
Before the break Grade 8s used and learned about microscopes. They were also asked how microscopes fundamentally changed our view of the world. This was followed by students learning the organelles within a cell and in groups they came up with various cell analogies that they shared with the class.
In Math we worked on a Golden Ratios Assignment. Students measured different body parts and tried to find if there were any golden ratios to be found in the human body.
Students did a quick review of Ratios, Rates and Unit Rates today. If students still need to work on problems there are some attached below.
In Science students have been learning about microscopes and will be using them to complete a lab tomorrow. Overall, students should be able to explain how microscopes have changed our understanding of the world.
