Cat Genetics Activities

I created this activity for an introductory biology class. It covers Mendelian and Non-Mendelian patterns of inheritance and has some suggest activities for practicing the Hardy-Weinberg equation. Since most of the questions ask you to cross a cat that you found there is no answer key. Teachers, please feel free to use this activity in … Continue reading

The making of a tabby cat

I’ve found it quite fascinating to look into cat genetics over the past week. I should have my entire planned activity for my bio students to share by next week, but in the meantime I thought I’d write about the agouti and tabby genes. The presence of a dominant agouti gene affects pigment distribution along … Continue reading

Why is there green foam on the lake?

I’ve been canoeing a lot this summer, so I’ve also seen a lot of notices about blue-green algal blooms, but this past weekend took it to a whole other level with piles of green foam on the beach and beautifully, but disturbingly coloured banks. While these blooms are relatively common regardless of conditions, warming climates … Continue reading

What is neuroblastoma?

As I continue to ride in support of the Sick Kids Foundation through the Great Cycle Challenge Canada, I’m also continuing to learn more about childhood cancer. Through the challenge I’ve heard about incredible kids and their families and the fights that have been won, lost, and are still in progress. They inspire me to … Continue reading

Consider where the bike lanes are

One of the key factors when I was looking for a home was bikeability: how safe would the area be for me on my bike. This did significantly restrict my search areas and it turns out one of the bike paths was actually horrendously dangerous and another was removed from the area I chose. But … Continue reading

What’s cool about the nest in my yard

Several years ago, while I was living in my previous home, I had a wasp crawl up my pants on Halloween (October 31, which by the way is pretty cold where I live), while I was standing at the sink washing dishes. This didn’t end well for me (they figured I had been stung around … Continue reading

Amplifying voices

In lieu of writing my own post today, I wanted to share some resources on breaking down systemic barriers in STEM (science, technology, engineering, and math). This is #BlackBotanistsWeek on twitter. This is a great opportunity to find out about cool people studying plants. I love how this resources page for #shutdownstem breaks it down … Continue reading

A Story…

In the past several weeks I’ve been reflecting a lot on racism and systemic racism. I’ve read Superior: The return of race science by Angela Saini and White Fragility: Why it’s so hard for white people to talk about racism by Robin Diangelo. I’ve added other books to my summer reading list as well. This … Continue reading

Suppressing my appetite

So yesterday I completed a sprint duathlon. Just for fun and on my own because we are still in the midst of social distancing due to the Covid-19 pandemic. In the morning I got up and had some Greek yogurt and fruit and then I went and did a 5 km run, 20 km bike, … Continue reading

Why is the water so brown?

When you’re used to clear water coming out of the tap it’s easy to make assumptions about how clean a water body is based on how clear it is. This means that most people assume that the North Saskatchewan River through Edmonton, Alberta, Canada is pretty dirty, particularly in the spring. The visible brown colour … Continue reading
