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.

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  AntiGravity 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 nonnewtonian 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.
Today, students worked on some order of operations problems involving integers. Any students who want to continue to practice word problems when more than one operation has to be completed can practice some word problem using BEDMAS attached below.
A reminder that the unit test for Integers is on Thursday, November 15. Students who want to continue to practice more word problems I have attached some below. Tomorrow we will move onto Order of Operations using Integers and on Wednesday we will be completing a review assignment.
Today in class students worked on using a density table and density calculations, including how to manipulate a formula. This will set us up for making a density gradient tomorrow in class. We will also have a bit of time to finish the density work from today. Some students will want to complete some of the work at home tonight and will need the density table in order to guess what substance the answer will be. I have attached the table below.
In case you need your density triangle and forgot it at school. I have attached a copy below.
At the end of last week we completed the main concepts of Integers with how to divide integers. This week we will move onto using Order of Operations to solve integer problems, more complex problem solving and a review assignment on our Integer Unit as the Unit Test will be on Thursday, November 15.
Upcoming Dates: Monday, November 12  Eric Walters Visit Thursday, November 15  Integers Unit Test Monday. November 19 to Friday, Nov 23  Scholastic Book Fair in the Learning Commons Thursday November 22 to Friday November 23  Parent/Teacher/Student Interviews  NO CLASSES Following the Viscosity and Flow Rate Lab we have moved onto another property of fluids, Density. This week we will continue with completing some Density calculations and a class demo of a density gradient. Classes were curious about the density of water and how that played a role in why we can't "walk on water" so this week we are hoping to also do an investigation on a nonnewtonian fluid. Below are the notes covered on Density. The particle model of matter as a way of explaining density was mostly a review for most students though using the density table and formula were new concepts that we will delve into in more depth this week.
This week we focused on multiplying integers. Today we started focusing on word problems. Attached below are problems that students can work on if they did not finish them in class/extra practice.
Students moved on to the next property of fluid, Viscosity and Flow Rate. Students should know what viscosity is, examples of fluids with high and low viscosity, how the particle model of matter explains this property as well as how the particle model of matter, shape and size of particles and internal friction are related. Below are the notes discussed in class. These were followed by a flow rate lab.
