Teaching Idea – Forcing Bulbs

Teaching Idea – Forcing Bulbs

Over Christmas, I had the pleasure of lounging around in a house that is loaded with plants… including blooming ones. Usually I just keep my mouth shut and leave anything associated with plant material to the very capable care of my wife. But I couldn’t resist asking about the hyacinths she had made bloom during the holiday season. I thought that the growing bulbs might be of use to science teachers who want a novel way of studying root systems,…

Teaching Idea – CO2 Powered Cars

Teaching Idea – CO2 Powered Cars

There’s nothing more fun than racing things at high speed! But how to do it in a safe, semi-controlled, educational manner? One great idea is using CO2 cartridges to propel balsa-wood based vehicles. Here’s some of the the details! First of all, let’s look at a few of the creative cars. These babies are about a foot long, and the bodies are carved out of raw chunks of balsa. In order for the racing to be fair, wheels and axles can…

Teaching Idea – Toy Car Speed

Teaching Idea – Toy Car Speed

To introduce (or review) the concept of average speed for physics students, there’s nothing more fun than measuring the speed of toy cars! Students are provided with a selection of toy cars and then asked to assess average speed of the vehicle. I highly recommend buying a few toys from your nearby “dollar store” – these toys often have strange behaviours and idiosyncrasies that make the task just a little more challenging! Students are allowed to use any technique they…

Teaching Idea – Cutting a Dry Cell in Half

Ever wonder what’s inside a dry cell? Apologies to the Energizer bunny, but here is a cell that has been chopped in half; The parts are a little different from the old zinc-carbon cells; A – combination zinc powder/alkaline electrolyte paste where electrons are released (anode). B – brass conducting rod where the released electrons are collected. C – hard to see in the above diagram, but this is a fabric that separates anode from cathode. D – mixture of…

Teaching Idea – Owl Pellet Dissection

It’s always a fun activity to dissect owl pellets – if you’ve never done it before, you really should give it a try, you can learn a lot about owls and what they eat. Here’s a few pictures from a ScienceMan grade 7 owl pellet lab: As long as you are using owl pellets from biological supply companies, this activity is perfectly safe – the owl pellets are fumigated so as to eliminate any chance of disease. The pellets are…

Cutting the Cable

Cutting the Cable

You don’t have to do much research to learn that people are dropping their pay TV services in record numbers. It’s not hard to imagine why. Personally, I finally got sick of paying $100/month cable bills for a bunch of junk channels that I never watch. It’s only due to laziness that I never cut my cable a long time ago – I was afraid of the hassle, but ironically, it’s been a lot of fun switching to alternate sources…

Project Adult Literacy Society – A Very Noble Cause!

Project Adult Literacy Society – A Very Noble Cause!

When people think about English as a Second Language (ESL), we often don’t consider the full implications of needing to get proper language training. It’s often a lot more serious than just being able to participate in everyday conversation. Consider that many immigrants may want to qualify for colleges or training programs. For example, how do you pass an entrance exam for a science program, when you don’t know science vocabulary in the English language? Thankfully, there are some wonderful…
