Can Crushin' Experiment
Just a little experiment where we explore the properties of water and the effects of expansion and contraction of water from liquid into gas, and from gas back into liquid. We can observe how this can create a vacuum which can cause a can to be crushed. Very fun experiment!

I Saw a Hawk (and why that matters)
Просмотров 62 часа назад
When I was a kid I never ever saw a hawk once. Now it is a pretty common occurrence for me to see Hawks swirling over the Don Valley Parkway and just generally around the city of Toronto where I live. This is a very exciting development, it has to do with the fact that we stopped using DDT because it was killing the big birds. Guess what, and we made a change. The big birds came back. It is pos...
Another Day on the Water, Pog Lake
Просмотров 1714 часов назад
Another great day kayaking on Pog Lake in Algonquin Provincial Park. We see some birds feathers and discuss whether they are from a fledgling bird's first flight, some beautiful water and sunshine, discuss the origins of the word Ontario in the indigenous language it came from. We also have a beautiful camping and kayaking and traveling on the lake!

    • @davepluscience
      @davepluscience 7 дней назад

      It seems that it is a little more complex than that. Trees can produce yellow pigment without using any energy (the pigment is always present, hidden by the green chlorophyll) but the leaves must actively produce the red pigment. There are theories about why trees expend energy to produce red pigment and stress is one of them. This article explains what I am talking about: www.earthdate.org/episodes/why-some-trees-splurge-on-red#:~:text=Under%20stress%2C%20plants%20may%20also,a%20greater%20harvest%20of%20nitrogen.

    • @davepluscience
      @davepluscience Месяц назад

      I can do a short on that. The short of the short is that the universal constant is something like pi. If Pi describes the relationship between the circumference and diameter of a circle. Then the universal gas constant describes the relationship between pressure combined with volume and number of atoms combined with temperature in a closed system. I guess that was a little bit long actually. I will make a video about this. Thanks for watching!

    • @davepluscience
      @davepluscience Месяц назад

      Think about it this way: you can't see anything without light, therefore, when you see a color, you are seeing light. When you see an object, you are observing light bouncing off that object. Different objects absorb and reflect light energy at different frequencies. I know that sounds fancy, but basically all I'm saying is different objects reflect different colors of light and absorb different colors of light. A red object reflects red light, a blue object reflects blue light, a white object reflects all the light and a black object absorbs all the light. It's s not the object that provides the color, it's the light. In the dark, we would not see the object at all. I hope that helps, I hope it doesn't make you curl up even deeper into your existential ball. The world may be a little bit more complicated than you might have imagined, but once you start looking into it, it's also way more exciting!
