Grade 7 Math

Since we finished up our Geometry strand on Friday, we will be starting our unit on Linear Relationships (aka My favourite unit of the year). We will be discussing patterns and rates and how we can represent them in different ways. Groups will be working on a stop motion video project, we will throw some Barbie dolls over the railing of the stairwell, and program some robots. This week will be reviewing patterns and number sequences, extending patterns, and writing recursive pattern rules. We will also be classifying patterns as increasing or decreasing and linear or nonlinear. Students looking for some additional resources can check out the following:

Grade 7 Science

A crime has been committed. My Yoda stuffy has gone missing. Four clues have been left at the scene of the crime: a ransom note with fingerprints, the pen markings on the ransom note, a crushed pill, and a spilled mechanical mixture. Student detective groups have to develop procedures to test each of the pieces of evidence and compare their results to the suspect dossier in order to determine the one who did the crime. Students will be given four lab days and one paperwork day. Students can refer to the workspace throughout the process for more details.

Also, on Friday (for 7-09) and next Monday (for 7-10), students will be writing their test on the second half of the Pure Substances and Mixtures unit. More information can be found HERE.

Finally, a reminder to all students who have missing assignments that they need to hand them in before the end of the day this Wednesday. After this point, they will receive a zero. Student are advised to check their school email to see if they received a message regarding missing assignments. This post has more details on how to make up the missed work.

Solubility, Dissolving and Separation Test (Science)

On Friday (May 3) and Monday (May 6), the science students will be writing their unit test for the Pure Substances and Mixtures unit. This test will cover the content from the second half of the unit. Here is a rundown of the topics and some example questions:


Part A (Knowledge and Understanding)

  • Multiple Choice (13 questions)

Part B (Communication/Application)

  • Paragraph answers (4 questions)


1) Solubility and Solutions

  • Terminology: solute, solvent, solution, unsaturated, saturated, supersaturated, dilute, concentrated, soluble, insoluble

2) Rate of Dissolving

  • Terminology: rate

3) Methods of Separating Mixtures

  • Terminology: sorting, magnetism, sifting, floating/settling, filtration, distillation, evaporation, chromatography, crystallization

Students looking for some additional resources can check out the unit review questions for Solutions and Dissolving and Methods of Separation. Also, students are encouraged to check out some of the links in the workspace (blue and pink sections) to further reinforce their understanding.

Happy reviewing!

Missing Science Assignments

Recently, I handed back several science assignments. At this time, I notified students who had not handed in the assignments that I would be providing an additional copy and a week for them to submit the assignment before I would no longer accept it.

The following assignments will be accepted as long as they are submitted by next Wednesday (May 1). If I do not receive the assignment by this date, the student will receive a “zero” on the assignment.

I believe in deadlines. I think that they are essential in helping students with time management and responsibility. Saying that, many students who get a “zero” don’t seem to care. It is as if they think that they have gotten away with not having to do the assignment. I would rather that each student actually completes the work!


Here are the three assignments that I will allow students to re-complete:

1) Particle Theory Poster (originally due March 5)

This was a small task at the beginning of the unit to help students remember the PArticle Theory. Students had to draw and colour a small diagram or cartoon depicting each of the points of the Particle Theory. They were given one class period to complete this.

A template to help students can be downloaded HERE.


2) Classifying Matter Lab (originally due March 8)

While learning about the different classifications of mixtures (solutions or mechanical mixtures), we completed a lab which involved students mixing various substances (oil, vinegar, juice crystals, salt, etc…) with water and then classifying the mixture. There were a few follow up questions to complete.

Students can download a copy of the lab write up HERE.

Although I don’t have the time to redo the entire lab with the students, I did complete the lab myself after school and am including my results in the picture below. Students are to write their hypothesis and then use the picture to complete the lab.


3) Dissolving and Solubility Simulation (originally due April 10)

While learning about solubility curves and the effect of temperature on solubility, we used an online simulation to see how the saturation changed for 5 different solutes at various temperatures. Students can access the online simulation HERE.

Students can download a new copy of the assignment HERE.


If students are missing the Mystery Matter lab, this was a major lab (it took us three days) and therefore will not be setting up everything again. If students find their copy of the mystery matter lab and are able to complete it I will still accept it by Wednesday. If they are unable to find their copy, unfortunately I am not providing new copies for this assignment.

I will be emailing any students (and CCing their parents) who are missing any of the above assignments (hopefully by the end of the day Saturday). This is a one-time deal. In future, late assignments will have a short grace period (1-2 days) following the due date (as long as the students speaks to me personally about why it was late) before it becomes an automatic “zero”. Students are encouraged to read the “What’s up this week” post regularly as all due dates are included in the post.

Thanks for your understanding and support in this matter.

Happy Easter and WUTW (April 23-26)

Happy Easter everyone! Hoping you were able to get out and enjoy the amazing weather Sunday and Monday. We have another four-day school week coming up along with some important dates and events:

  • April 22: Easter Monday (no school)
  • April 26: SWYK: Dilatations on the Coordinate Grid (math)
  • May 3: Unit Test on Dissolving and Separating Mixtures (7-09 science)
  • May 6: Unit Test on Dissolving and Separating Mixtures (7-10 science)
  • May 8: CSI Procedural Write up DUE (science)
  • May 8: Catholic Education Week Open House (4:30-6:30)
  • May 14: CSI Accusation DUE (science)
  • May 14: 7/8 Quebec City Trip
  • May 17: PD Day (no classes)
  • May 20: Victoria Day (holiday)


Grade 7 Math

This week will be our final week of Geometry for the year. We will be continuing to discuss similar shapes and scale factors but this time will be using the coordinate grid to perform and describe dilatations. TUesday to Thursday will be spent practicing various enlargements and reductions of shapes based on specific scale factors a from a centre of dilatation either on the shape, on the origin, or from another point on the grid. On Friday, students will be writing a short (one page, two question) assessment to prove that they have mastered the concept.

Here are some online resources that students could check out at home in preparation:

Grade 7 Science

On Tuesday, we will be discussing the final topic in our Pure Substances and Mixtures unit: methods of separating solutions. The test for the second half of the unit will not be until May 3 but we will be taking some time on Wednesday to review the concepts. I will also be writing a blog post which outlines the test topics and some review material that can be used. Then starting on Friday (Monday for 7-10), students will be complete the CSI project – more info to come!

Also, students were made aware last week that they may be missing certain assignment. I will be discussing these missing tasks with the student first and will be giving an opportunity for some of the assignments to be completed over the next week. I would much rather students actually have to complete the assignments/lab as opposed to just accepting a “zero” for the missed work. I will be notifying parents of the missed assignments at some point this week.

Cool Opportunity = Paris Exchange 2020

Would you like your 13-18 year old son or daughter to travel the world and be immersed in the French language and culture?  Would you also like for them to do this affordably? If so, the Holy Trinity C.H.S. – Lycée Sainte Croix de Neuilly (Paris) EXCHANGE TRIP may be the trip of a lifetime!  Pending approval of the OCSB, selected students will be invited to participate in a cultural and educational exchange with the Lycée Sainte Croix de Neuilly, Paris, France.  This exchange will be open to students in all levels of French who will be in Grades 8-12 in the 2019-2020 school year. Holy Trinity families participating in the exchange program will host a French student in February 2020 and, in return, Trinity students will live with their French exchange partners in the month of March/April 2020. During the exchange, students will attend a variety of activities organized by the schools as well as the individual families. Please see Madame Pivato in Room 304 for more information.

Grade 7 Math

Last week, we reviewed some concepts from grade 6 including congruence and transformations. Students created tiling patterns (tessellations) in the form of artwork. This “Escher Art” is due on Monday (for students looking for the tutorials from class, they can find them HERE). This coming week, we will be starting to discuss similar shapes and will relate this concept to past number sense topics of percent and proportions. There will be a short assessment on Wednesday, which will involve both congruent and similarity.

Students looking for some additional support on these topics can check out the following:

Grade 7 Science

We have been studying solubility and factors affecting the rate of dissolving. Student lab groups designed their own experiments to test the impact of one independent variable on the rate of dissolving. Variables include: temperature, amount of solute, amount of solvnet, concentration of solvent, size of solute (sugar cube), stirring speed and container size. On Tuesday, we will be using analysing our results and the lab report will be due on Wednesday. Also, next week, we will be discussing methods to separate mechanical mixtures (include sorting, floating/settling, sifting, filtering, and magnetism).
