I know many of you are on summer break right now, but making lunches each morning is still happening at my house! I do not know about you, but I continually struggle with how to keep what I pack into the lunch warm by lunch time… well, I guess I have to turn to science in order to help me with this dilemma.
Let’s get started!

It always amazes me at the interesting STEM careers we have right here in southeastern Alberta!
I recently had the privilege of meeting a few Drone Specialists — top Engineers in their field. I was completely in awe at how they could fly those amazing little aircraft with such ease. Unfortunately, I have never been quite coordinated enough not to crash them… so I tend to observe more.
As I saw some of their pretty amazing stunts and maneuvers being performed, it reminds me how these pilots got started. It likely started in their Grade 6 classroom and the ability to master four scientific principles: gravity, lift, thrust and drag. I…

I do believe summer will “officially” start this weekend — I know the students are done school and now many of us are ready for a reason to celebrate (and Happy Canada Day!).
It has been a hot week, and I am sure it is going to get even hotter this summer. This makes me think sun safety should be a priority for all of us. Each and every one of us should wear sunscreen when outside and this week, I hope to show you why. Let’s get started!

Oh my we have had a couple of weeks of extreme weather right here in Alberta.
I think last I heard there were 10 confirmed tornadoes in one day in this province. This is unheard of — we rarely hear of one or two every few years. I truly hope that everyone did stay safe with this wild weather we are experiencing.
Perhaps you are as curious as I am, and wonder just what a tornado looks up close. I am not brave enough to be one of those “storm chasers” so I thought we could make our own.

The past month or so, I have spent a great deal of time at the baseball diamonds. Just when you think the pitch is coming in and it will be a home run, it is a strike. The ball seems to wiggle or dip, and then a miss… how does this happen?
The coach says these are “knuckeballs.” Hmmmmm… I think we had better turn to science to help us figure this out.
Let’s get started!

The beautiful weather this week has everyone outside participating in some really great summer activities.
I recently saw some children riding one-wheeled skateboards. Oh my, I can hardly imagine riding a skateboard with four wheels let alone one! Of course, this made me think perhaps I could — I just need to learn a bit about the science of skateboarding.
Let’s investigate further!

Materials
- Popsicle sticks
- Small weights such as some assorted washers

I can hardly believe it is June already. Where has the school year gone? As summer approaches, I thought it would be a good idea to find some useful science experiments we could have for when we are enjoying the outdoors. As an avid camper in the backcountry, this week, I thought we should learn how to make something that can guide us home just in case we ever get turned around on one of those long hikes.
Let’s get started!

So why not just quit
I started using Social Media in 2007.
I’ve never really regretted doing what I do. It has gained me a community of people that I learn from daily. I’m so grateful for that. I can’t imagine how I would have ever learned what I know these days if it wasn’t for a network of people who inspire me to do better.
I’ve always believed in the concept of open learning and open sharing and it’s a way that I give back, in appreciation to those who have kept me learning.
Twitter has always been ground zero for me.
I’ve built everything that I’ve done around it, for the most part. When changes were imminent, I did move to Mastodon hoping to find the same success there. But, it wasn’t to be. I ended up getting limited a couple of times for doing what I was doing. I solved that by…
