If you consider yourself a lifelong learner, online courses are an easy and affordable way to hone your skills, challenge your brain, and maybe even discover a new interest or hobby. You can find e-courses on everything from interior design to graphic design, and many of these classes are free on websites like Udemy, Coursera, and edX. (But if you want a certificate to prove you completed the program, there is typically a fee attached.)

Ready to dive into some lesson plans? We’ve selected 10 of the coolest classes you can take right now from the comfort of your own home.

1. Dog CPR and First Aid

Many non-medical professionals are now CPR-certified, but did you know that similar first aid techniques can be used on dogs in emergency scenarios? This course covers CPR and the Heimlich maneuver for canines, as well as explaining how to read a dog’s vital signs. One of the lessons also addresses emergency prevention, including topics such as car safety, toxic foods and plants, and disaster preparedness. Whether you have a fur baby of your own or just want to be ready to rescue an animal in need, this is the course for you.

2. Neuroplasticity: How To Rewire Your Brain

Old habits die hard, but it’s still possible to make meaningful, lasting change in your life. Taught by psychologist and Brain Academy founder Gregory Caremans, the course is ideal for anyone who wants to form healthier habits, minimize painful memories, or stop procrastinating (indeed, there’s a whole chapter dedicated to this last topic). No prior knowledge is necessary, but be prepared to give your brain a full workout. The class includes lots of exercises that will help you reshape your brain in the most literal sense.

3. The Science of Well-Being

After you’re done rewiring your brain, you can teach it how to be happier with this class from Yale University. Psychology professor Laurie Santos starts off by refuting common misconceptions about the things we think will make us happy, despite scientific evidence to the contrary. Fortunately, these biases of the brain can be overcome, and a large chunk of the class is dedicated to strategies that can be used to achieve a greater sense of well-being.

If Santos's class leaves you wanting more, you can also sign up for The Science of Happiness, a free class from the University of California, Berkeley's Greater Good Science Center. It's available on edX for free (with an option of buying a $49 certificate upon completion).

Sign up for Santos's course on Coursera for free. The optional certificate costs $49.

4. The Rise of Superheroes and Their Impact On Pop Culture

If you’re still mourning the loss of legendary comic book creator Stan Lee, you may enjoy this course from SmithsonianX, which features some of the superhero-themed knowledge that Lee imparted during his time on this Earth. You’ll also hear from another comic book maven, Michael Uslan, who served as executive producer of The Dark Knight series and The Lego Movie. After six weeks, you’ll be able to explain how the birth of the first-ever superhero in 1938 launched a global phenomenon that continues to inform art, pop culture, and even ethics.

5. Greatest Unsolved Mysteries of the Universe

What caused the Big Bang? What is our universe made of? Is there life in outer space? Two astronomers from the Australian National University set out to address some of the lingering questions in modern astrophysics. You may walk away from this course with more questions than answers, but you’ll have a more informed take on life’s greatest mysteries, as well as a better understanding of why exactly they’re so tough to crack.

Sign up on edX for free. The optional certificate costs $50.

6. The Kennedy Half Century

Calling all history and presidential trivia buffs: This course from the University of Virginia provides a comprehensive understanding of the legacy that John F. Kennedy left behind. It covers J.F.K.’s rise to power, presidency, and assassination, and explains how these momentous events have had a long-lasting impact on the public, media, and presidents who came after him.

Sign up on Coursera for free. The optional certificate costs $49.

7. The Science of Beer

If Alton Brown was to teach a class on beer, it would probably look similar to this offering from Wageningen University & Research in the Netherlands. You’ll learn how your beloved brew of choice is made and what exactly makes it taste so delicious. Fair warning, though: You’ll also learn about some of the unsavory health effects of imbibing too much beer. There’s a business angle, too—instructors provide an overview of how beer ends up in the supply chain and how marketers try to influence consumer behavior.

Sign up on edX for free. The optional certificate costs $49.

8. The Music of the Beatles

With 13 studio albums to their name, The Beatles released enough material to dissect, analyze, and enjoy for decades to come. This class from the University of Rochester charts the band’s evolution as musicians, from their early experiences in Liverpool and Hamburg to their psychedelic phase to the release of Abbey Road, the last album they recorded. (Although, as you’ll likely learn in this course, Let It Be was the last album they actually released).

9. Aquaponic Gardening: Growing Fish and Vegetables Together

Healthy, sustainable food doesn’t always come cheap, so why not raise your dinner in your own backyard? Author and aquaponic gardening expert Sylvia Bernstein will guide you through the basics of raising fish like tilapia, bluegill, and catfish in captivity. In turn, the waste from those fish can be used to nurture an entire fruit or vegetable garden. Sylvia and her husband, Alan, will demonstrate the eco-friendly techniques you’ll need to know to yield a bountiful feast.

Sign up on Udemy for $25. A certificate of completion is included in the price.

10. Passive Income: Top 10 Legit Ways to Make Money Online

Everyone wants to know how to make more money with less effort. Entrepreneur and IT professional Victor Gorinov's Udemy class is designed to help you figure out how to do that. He’ll introduce you to the basic concepts involved in earning passive income, tackling options like affiliate marketing, domain trading, investing in stocks and real estate, monetizing your YouTube account, and selling your photos and videos to stock image websites.

Sign up on Udemy for $12. A certificate of completion is included in the price.

Can You Find All of Kevin McCallister’s Booby Traps From Home Alone?

20th Century Fox
20th Century Fox

Kevin McCallister's house in Home Alone (1990) has become an iconic movie landmark. If you can't make it to the Chicago area to see the real location in person, you can explore the house as it appears in the film—booby traps and all—using the 3D map below.

In honor of Home Alone's 30 anniversary in 2020, home services company Groundworks put together this 3D model of the home where Kevin foils the Wet Bandits. Harry and Marv didn't fare so well in the house, but fans of the movie may have a better shot at spotting all the hidden dangers. Pitfalls hidden throughout the map include the blowtorch that scorches Harry, the tarantula that terrorizes Marv, and the paint cans that hit both intruders.

There are 14 booby traps in total—see if you can spot them all. After giving up, you can check the locations of each trap here.

Groundworks

The pranks in Home Alone are comedic on screen, but in real life they would be much less family-friendly. A doctor diagnosed Marv and Harry's injuries in 2018. Even if they were able to walk away from Kevin's assaults, they would likely sustain facial fractions and third-degree burns. Here are more facts about the movie to check out this holiday season.
