Science is one of the best ways we have of understanding what’s going on around us. In Crash Course Scientific Thinking we’ll explore the foundational principles that underlie scientific thought.
Course Description
In 7 episodes, Crash Course Scientific Thinking will teach learners the foundational principles underlying scientific thought, pulling back the curtain on processes like peer review, interrogating what makes sources reliable (or not), unpacking how consensus is reached, and revealing how scientific understanding changes over time. Ultimately, learners will gain the ability to think more critically about the scientific information they encounter in their everyday lives.
Series Objectives
- Describe the dynamic, communal nature of science, articulating the roles of uncertainty and consensus.
- Explain the role of peer review and replication in science.
- Unpack the potential for bias and error in science and understand its self-correction mechanisms.
- Understand the role of specialization in scientific expertise.
- Interpret primary, secondary, and tertiary sources, and use lateral reading to verify claims.
- Understand basic statistical language used to describe scientific findings.

Hank Green: Science is everywhere, and you're interacting with it all the time. In school, but also in the news, on your For You page, around your dinner table, and right here on YouTube.
That's a good thing. Science is one of the coolest things our species has going for it. Right up there with art, literature, and bidets.
But when it's coming ar us all the time from all kinds of places, it can be hard to make sense of it. Much like a bidet.
These days, we're bombarded by news stories about science. Our feeds are full of everything from nutrition to climate change.
On top of that, our own brains are hard-wired to deceive us. We all have cognitive biases that, when left unchecked, can make it even harder to know if something is supported by evidence or not.
But science isn't just a buzzword. It's a unique way of uncovering knowledge that's dynamic communal, and self-correcting.
And it's one of the best ways we have of understanding what's actually going on around here.
Thinking scientifically helps us push past biases and agendas and clickbaity headlines toward the elusive capital-T Truth.
Hi, I'm Hank Green. I started making YouTube videos in 2007 with my brother John.
Now, I am a go-to internet science guy, having produced and hosted literally thousands of videos and podcasts all across the internet.
I also co-founded Complexly, which produces this show, Crash Course, as well as SciShow, and nearly a dozen other educational YouTube channels.
In 7 episodes, Crash Course: Scientific Thinking will explore the foundational principles that underlay scientific thought.
We'll pull back the curtain on peer review, take a magnifying glass to scientific sources, unpack big ideas like consensus, and consider how what we know about the world grows and changes over time.
And we'll explore scientific experiments, processes, and discoveries, to figure out how science has impacted our lives.
By the end, you'll be able to think more critically about basically everything, from your science textbooks, to the news on your feed, to that guy who keeps yelling at you about science on TikTok.
We'll learn about how to sift through information wherever it comes from, to inch ourselves closer to a nuanced, shared scientific understanding of the world. And you'll walk away a more savvy consumer of science information.
[Eats brain]
So join us here next time, when we will ask a big question: can we trust our own brains?
This episode of Crash Course: Scientific Thinking was produced in partnership with HHMI BioInteractive, bringing real science stories to thousands of high school and undergrad life science classrooms. If you're a teacher, visit their website for resources that explore the topics we discussed in the video today.
Thanks for watching this episode of Crash Course: Scientific Thinking, which was filmed in Missoula, Montana, and was made with the help of all these nice people. If you want to keep Crash Course free for everyone forever, you can join our community on Patreon.
