Science, Phys. Ed., and The Design Process

Science, Phys. Ed., and The Design Process

We often say that doing something with a machine requires less work. In this design competition, grade 8 students were challenged to help upgrade the gymnasium and physical education programming here at OJCS. Using their knowledge of simple machines, they had to use the design thinking process to design, test, and build a simple machine prototype that enhances our physical education curriculum. Physical education equipment is expensive and gets used up with frequent use. PE is a favourite class for many OJCS students and anything we could do to help upgrade the gymnasium’s physical space or by providing more games and equipment would benefit the school and student Ruach.

What is the Design Thinking Process?

The 5 steps in Design Thinking (link)

  • EMPATHY – Display an understanding of the problem you are solving by gaining real insight into the needs of the end-users (the OJCS students)
  • DEFINE – Identify a key area that a product can solve and provide focused research that helps provide a solution to a specific goal (Research of Simple Machines)
  • IDEATE – brainstorm a variety of solutions to the problem (Documentation of all ideas)
  • PROTOTYPE – create a model based on rough drafts or blueprints (The physical build!)
  • TEST – the prototype is shared with others for feedback (Documented feedback)

How did they do it?

Students had to decide what to build, connect our simple machines learning from Science class as part of their research, and create a plan for their prototype. They then had to determine what materials they needed next by searching through Home Depot’s website and placing their order with their teacher. And then, the fun part…

Not only did the grade 8’s successfully link the Science and PE curriculum using the Makerspace to improve the PE department, but it also connected our OJCS students in the process. On Innovation Day they wowed the judges, parents, teachers, and definitely their younger peers, who were enthusiastically asking when they would get the chance to participate in the Simple Machines Project. The grade 8’s should be proud of the legacy they are leaving behind and for starting something new for younger grades to further innovate.

Grade 6 – Electricity

Grade 6 – Electricity

This post will contain all of the grade 6 lessons on electricity. Students will be learning about the short and long-term impacts of electrical energy technologies in Canada on society and the environment. They will learn how circuits work by building their own series and parallel circuits and assess choices that reduce personal use of electrical energy.

Lesson 1: Renewable Energy


Lesson 2: Renewable vs. Non-Renewable Energy

Energy Quiz Review Sheet

Lesson 3: Series vs. Parallel Circuits

Lesson 4: Building Circuits

Lesson 5: Fixing Electrical Problems

There are so many uses for electricity. But what happens when something isn’t working right? Maybe your computer speakers are not working or your refrigerator isn’t staying cold. What do people do? They often need to take their appliance in to be repaired or have a technician come to the house to repair the appliance. The technician has to figure out what is wrong and why the device is not working properly. This process is called troubleshooting. Let’s practice some troubleshooting skills to solve electrical problems.

Lesson 6: What is Static Electricity?

A form of Static Electricity is lightning… check out the video below of some amazing lightning strikes.

Lesson 7: Energy Conservation and Home Electricity Audit

Lesson 8: How Do Batteries Work?

JNF Hackathon

JNF Hackathon

OJCS students in grades 7 and 8 competed in the countrywide Hackathon this week put on by the JNF. The students were split into teams and tasked with ‘hacking’ a problem.

What is a Hackathon?

You might be asking the question, what is a Hackathon? And does it involve breaking codes with computers over an extended period of time? Not in this case. A Hackathon is a rapid, time-bound, pressurized problem-solving event. The JNF Canada virtual Hackathon is a non-technical Hackathon where students gathered virtually to collaborate and solve problems.


The Challenge for Each Team

This year’s challenge was to find creative solutions in order to offer “accessibility in nature” for all.

Mentors and Judging

Teams of students from across Canada worked collaboratively to come up with creative ideas and presented their innovative solutions to a panel of judges. Teams were provided with a mentor.  The role of the mentor was to support and guide the team in developing their ideas and delivering their solutions with clarity.


Congratulations to Sarah-Amanda, Noah, Joel, Mia, Yossi, and Maor on their 3rd place finish for their amazing idea and presentation on Peddle Boats that even included a sign language aspect.

Some Key Concepts About Elements and their Atoms

  • Atoms are made of extremely tiny particles called protons, neutrons, and electrons.
  • Protons and neutrons are in the center of the atom, making up the nucleus.
  • Electrons surround the nucleus.
  • Protons have a positive charge.
  • Electrons have a negative charge.
  • The charge on the proton and electron are exactly the same size but opposite.
  • Neutrons have no charge.
  • Since opposite charges attract, protons and electrons attract each other.
