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.
Used dental floss under a scanning electron microscope.
In math today we reviewed 2 and 3 term ratios and part to part/part to whole ratios. We moved onto rates starting with which rates we use and observe in real life. This led to the discussion of unit rates and how ofter we use them especially when pricing items of different sizes.
For extra practice students can do the following problems.
In Science, students continued to work on their Stem Cell Grows Up Assignment. It will be due on Monday, December 10.
IMPORTANT UPCOMING DATES:
We have moved onto the next unit in Science, Cells and Systems. So far students have covered two topics:
1) Characteristics of Living Things
2) Levels of Organization - Notes are attached below. Students will spend some time this week working on an assignment based on levels of organization.
,In Math students have been working on converting percents, fractions and decimals. Much of it is review from last year but in Grade 8 students are expected to further their understanding by being able to problem solve with percents greater than 100% and percents between 0 and 1.
This week we will be moving on to Ratios, Rates and some Proportional Reasoning.
Students will have a unit quiz on Mix and Flow of Matter on Tuesday, November 27. The following are the main concepts/vocabulary that we learned throughout the unit.
1) Particle Model of Matter – 5 parts
2)States of Matter – Solid, Liquid, Gas,
3)Changes in States of Matter – Fusion, Melting, Freezing, Solidification, Condensation, Sublimation, Deposition, Evaporation
4) Classification of Matter – Heterogenous/Homogenous/Pure Substances/Mixtures/Elements/Compounds
5) Separation of Mixtures
6) Solubility – Insoluble, Soluble, Saturated, Unsaturated, Solubility Tables/Graphs
7) Viscosity / Flow Rate
8) Density – Calculation, Reading a Density Table
9) Buoyancy - Anti-Gravity Force, Average Density, Archimedes Principle
For students who would like some extra guidance, a study guide is attached below covering the concepts of this unit.
A follow up on non-newtonian fluids, students completed an Oobleck activity.
This week students designed a boat made of tin foil and had a contest of which boat could hold the greatest amount of pennies (remember those?) before sinking.
