Our second online learning unit was physics, where we focused on electricity and its applications that are used by professionals like AB Electrical & Communications. After briefly discussing the different sources of energy to start the unit, we spent an entire class learning about the ins and outs of static electricity where students once and for all understood the mechanics of how those pesky static shocks work when we grab a doorknob, especially in the winter months. We finished off our discussion on static electricity by discussing the different ways to create and dissipate it.

The rest of the unit was all about current electricity and the different ways we produce it. We first learned about the two types of current electricity, alternating current (AC) and direct current (DC), focusing on the latter. We then moved on to the major components of electric circuits, electrical quantities (current, voltage, resistance) and looked at how each of them behave in series and parallel circuits. Students observed these quantities via online circuit simulators and recorded what they saw and discussed their observations. We ended the unit by looking at the different sources of electricity (solar, wind, hydro, nuclear, fossil fuel) and discussed the advantages and disadvantages of each.

Kahoot Trivia Challenges

The second meeting of the Boardgame Club has staff and students going head to head in trivia games of various topics using the online platform website Kahoot! Kahoot! is a game-based learning platform, used as educational technology in schools and other educational institutions. From news of the week, Marvel, and general knowledge to pop culture, we tried answering questions correctly to see who would reign as trivia grandmaster. At the end of the hour everyone learned something new as no one can know everything. It was another week of laughs and fun and we are eager to see what we will play next.

Doodles & Giggles

In our inaugural meeting last Wednesday, the Boardgame Club had 10 students drop in for an hour of doodles and a lot of laughs as we played a game called Drawful 2. The game involves a group of people each of whom are given a different prompt to draw. After everyone draws their prompt, the group takes turns guessing each players’ prompt and points are awarded for the correct guess as well as answers the group considers to be correct or worthy of a vote. We had a lot of laughs and everyone thoroughly enjoyed the hour. We can’t wait until next week’s game.

Grade 11 Biology Unit 3 – Genetics

Jumping back into the thick of things after our break, the new virtual biology classroom delved into the brand new unit of genetics. We began the unit by discussing the structure of DNA and built up to what genes are and how they are expressed. Once we were comfortable with the structure and expression of DNA we looked at the process of how it replicates itself and then moved on to looking at the processes of mitosis and meiosis. Next we ventured into the world of genetic disorders, focusing more on the different types of disorders and looking at a few examples of each and how they manifest.

As the unit came to a close, we explored various reproductive technologies and their links to genetics and ended the unit by discussing the various ethical, social and legal issues related to genetics, genetics research and technology. This set up students to start thinking about genetic disorders and the various issues related to them, which is what their unit research project was centered around.

Grade 9 Science Unit 3 – Space Exploration

As schools and students have moved to online learning, the grade 9 science class is fortunate to have had the opportunity to do so with a fresh start on a new unit called Space Exploration. In this unit we started off by discussing the history of astronomical discovery and the important roles it has played in the evolution of our societies. We then moved on to exploring our own backyard by cataloging some of the characteristics of the planets in our solar system by exploring NASA’s planetary website.

After we were done in our own backyard, we ventured farther and father out into the universe, looking at all of the vast structures it has to offer. Eventually we spent an entire class talking about stars, their characteristics and how they live and end their ‘lives’. Upon learning about stars, we went back into deep space and learned about various astronomical phenomena, from those close to us such as solar and lunar eclipses, to the more exotic ones such as black holes, quasars, and pulsars. We ended the unit by discussing the various challenges of exploring space which prepared students for their mission to Mars assignment.
