Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

A lot or a little?

The parents' guide to what's in this movie.

Positive Messages

Hank Green and his crew show that exploring random questions about human life, nature, and the universe through science can be funny, gross, and fascinating.


Some videos include questions that deal with mature topics related to sex or the human body. For example, "The Sex Life of Early Humans," "Why Do We Have Butt Hair," "The Evolution of Male Homosexuality."


Mild profanity ("butt," "suck," "poop") sometimes used for scientific humor, effect.


Sponsors are briefly credited at the beginning of each SciShow video.

What parents need to know

Parents need to know that SciShow is a YouTube channel that uses science to answer interesting, odd, and sometimes risqué questions. Through the use of scientific information and newly released studies, host Hank Green (brother of author John Green) and his crew discuss topics about which many people often wonder. They lighten the academic info with lots of humor, some sarcasm, and a little innuendo. There are mild videos (8 Creepy Animals That Are Actually Harmless) to somewhat wild videos about mature (or silly, or both) topics. Some parents may find that some SciShow videos contain information that is not appropriate for less mature viewers (for example, The Sex Life of Early Humans, The Clitoris and Wilbur the Hognose Snake).

We recommend parent co-viewing of YouTube content for kids under 13. Please note that our reviewers watch between one and two hours of content to determine the general appropriateness of each YouTube channel. Some channels contain more variety within their content than others, and we do our best to capture the overall subject and tone to help parents make the best choices for their family.

What's the story?

It's anyone's guess what subject you'll see next on SCISHOW. The approximately 4- to 10-minute video topics range from scientifically serious (7 Super Toxic U.S. Sites) to personally private (Why Do I Shiver When I Pee?). While site creator Hank Green hosts many of the videos, there are some other male hosts and at least one female host, as well as guests from other YouTube channels. Many videos include charts, graphs, images (A New Secret Ingredient to Making Queen Bees), and other graphics to highlight important points in the host's presentation or to add some humor.

Is it any good?

For mature teens and adults who want scientific explanations for important and not-so-important topics, this YouTube channel will surely satisfy many a curiosity. SciShow's videos are almost always engaging, usually educational, and often cringe-worthy. Some videos' topics and the way they're handled can push the envelope of good taste. But the mix of scientific info, humor, and shock value usually works pretty well. The SciShow crew prove that answering questions about humans, nature, and the universe through science can be humorous, gross, and really fascinating.

Talk to your kids about ...

  • Families can talk about what's fascinating about science. What questions would you want to answer if you had your own YouTube channel? 

  • What do you think about the blend of comedy and science? Do you think it works here? Why or why not?
