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.

Makerspace Equipment: Introducing the Laser Cutter

As the OJCS makerspace team, we value and seek to prioritize collaborative PD time together. During our self-directed professional development day, we spent a portion of it setting up and developing our knowledge of how our Laser cutter works.

Here is our Glowforge Laser Cutter:

#GlobalMakerDay @theojcs 2022

#GlobalMakerDay @theojcs 2022

On Thursday October 20th, Science classes will participate in Global Maker Day. A day dedicated to learning, sharing, and playing while completing STEM-related challenges. Challenges will provide students to practice problem-solving, be creative, and have fun learning.

Students have been asked to collect items for the OJCS Global maker day, October 20th. We are looking for any cardboard boxes (think cereal boxes) toilet paper tubes, paint stir sticks, popsicle sticks, and plastic tubs (think yoghurt pots, sour cream tubs – clean please!) items to help with our creativity. 

The challenges are listed below.

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 4: The Periodic Table of Elements

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.
