NOSE CREEK GRADE 8

Math/Science

8E and 8B

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 PrincipleFor 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.

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 non-newtonian 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.
This week we reviewed the concepts of adding and subtracting integers. There will be a short review quiz tomorrow. If anyone would like extra practice I have attached some practice questions below and some word problems. Next week we will be moving onto Multiplying and Dividing Integers.
Upcoming Dates:Friday, Nov 2 - Adding and Subtracting Integers Quiz Monday, Nov 5 - Current Events Assignment Due Wednesday, Nov 7 - Picture Retake Day Monday, Nov 12 - Eric Walters Visit Monday, Nov 19 - Friday, Nov 23 - Book Fair Students have completed the solubility section of Mix and Flow of Matter. They completed a lab and a in class assignment on this topic. Today we moved onto Separating Mixtures. We will further explore this topic through some labs and activities. Attached below is the information for both topics.
A reminder that the current events assignment is due:
