    Correction:
    In this video, we conflate a hypothesis with a prediction. In science, a hypothesis is a tentative explanation for an observed phenomenon. It aims to answer: Why does something happen? A prediction, on the other hand, is a reasoned guess about what might happen if we test that hypothesis in an experiment.
    To revisit our egg example, a true scientific hypothesis might be: "Eggshells inhibit pressure from being released from eggs." We might test that hypothesis by microwaving eggs both with and without shells to see if pressure from the heat gets trapped, leading to explosion. If our hypothesis is correct, we predict that the shelled egg will explode and the shell-less egg will not.
    These two terms are often blended in textbooks, classrooms, and even at times by working scientists. But they are actually two separate, though closely linked, parts of the scientific process!

    This absolute master drops a Jeremy Bearimy reference. This person is clearly a cultured scientific genius. Really showing off the credentials with this one, Doctor.

    If you only learned one thing about science, this would be it. This is why we should respect science.
    It also teaches critical thinking skills which is, well, critical for all persons living in a complex society where everything depends on science.

    5:03. That could be Italians. There's a grape focaccia called Schiaciata con l'Uva: a bread filled and covered with grapes. If you have it warm, you'll be eating warm grapes - and it is delicious!

    I'm putting together a list of Crash Course videos for my kids to watch next month.
    In their elementary school, they don't quite learn everthing I got to when I was that young. Such as in 3rd grade, I learned about dna, rna, how to measure our weight and height, our blood pressure, heart rate, and we went to the StL Science Center for a field trip to do hands on learning. In 5th grade we learned about the scientific method. My kids elementary doesn't teach them til middle school. They learn more about animal science, such as habitats and their environmental needs to survive.
    I wonder if elementary schools tweak their science lessons based on where they live in the US. Like do areas that are more rural with a lot of wildlife, could that be why they focus more on habitats?
    I did my elementary learning in a city, not much wildlife compared to rural areas.
    But I can, hopefully, just get some straight answers by asking our states education department.
    I was curious why my oldest never got to partake in a district wide science fair in elementary school. They don't have them. 🤷‍♀️

    Since Dr. Saamy is an entomoligist, it would be great if there is a crash course on entomology too. Arthropods are the most successful phylum in the world since they are the most present organisms in the world other than humans esp., beetles.

    There should be a warning that eggs will still explode even when the shell is off, one should never microwave eggs unless scrambled. Many people have gotten hurt by this misinformation in the past, please correct this.

    • @jackiehannaford
      @jackiehannaford Год назад +4

      Can confirm - I was lucky I didn't get badly when my out-of-the-shell egg exploded on me. @howtocookthat has a really comprehensive video about it.

    • @MoonJarGirl1
      @MoonJarGirl1 Год назад +3

      I love How 2 cook that!! I wanted to get on the bandwagon. This misinformation should be changed so no one else gets hurt from the 'sploady eggs. It could really cause bad burns on your face and eyes!! Don't want someone naming Crash Course as to where they got the idea.

    FINALLY
    Ive always loved the idea of crash course, but had trouble connecting with most of the hosts. Even when it's been Hank it feels wierd seeing him in that setting cos I'm more used to off the cuff silly Hank.
    You know what though. This guys delivery reminds me so much of the fellah who hosted crash course space. The only crash course that I've seen in completion, and it started my absolute obsession with all things to do with cosmology and beyond. If this guy can do that for biology I'm so here for it.
    Also PS surely it's time to do crash course space part 2 😊 bring back that same guy too!!!

    Sonnet-To Science
    BY EDGAR ALLAN POE
    Science! true daughter of Old Time thou art!
    Who alterest all things with thy peering eyes.
    Why preyest thou thus upon the poet’s heart,
    Vulture, whose wings are dull realities?
    How should he love thee? or how deem thee wise,
    Who wouldst not leave him in his wandering
    To seek for treasure in the jewelled skies,
    Albeit he soared with an undaunted wing?
    Hast thou not dragged Diana from her car,
    And driven the Hamadryad from the wood
    To seek a shelter in some happier star?
    Hast thou not torn the Naiad from her flood,
    The Elfin from the green grass, and from me
    The summer dream beneath the tamarind tree?
