Science Questions

Science questions are a fun and interesting way to learn about planet Earth, organisms and the universe. In this section you'll find an incredible collection of science questions covering a wide variety of topics.


The genetic material from two parents combines to form a child. Can we throw a third set of genes into the mix?

You may have heard of Topsy the elephant and her sad demise at the hands of Thomas Edison. But what's the real story?

If you kiss your bowling ball, you'll bowl a strike. If you buy ice cream, you'll turn into a cold-blooded killer. What other correlations are not causations?

The Lizard King got a lizard. The physics king got a particle. And a long-dead king got a DNA match. What else non-king-related happened in the realm of science in 2013?

After the Japanese earthquake and tsunami in 2011, quadrotors assessed buildings not far from Fukushima. And they did it without being harmed by the kind of nuclear radiation that damages us humans. Do they have more tricks under their wings?

Search and rescue missions and extreme weather events often go hand in hand. Fortunately there's a wide range of technology that helps emergency service workers get a leg up in preparing for and handling the elements.

Bend but don't break: That's the idea behind many of these temblor-thwarting technologies. They may even allow a building's inhabitants to walk out unharmed and start picking up the pieces after the earthquake subsides.

Time is of the essence when trying to rescue people trapped at sea or in a crumbling building. But finding the victims can sometimes be difficult. Thankfully, cutting-edge technologies are taking the "search" out of search and rescue.

The scene of a disaster isn't a place of order, at first glance. But it's not just EMTs, firefighters and police officers competing for space. In fact, those professionals would be at serious risk if there weren't also engineers on the scene.

Seven million (and counting) YouTube viewers can't be wrong. Nano quadrotors are tiny, autonomous flying machines that have the Internet buzzing.

Most loss of life in earthquakes comes from people being trapped inside crumbling buildings. And engineers have come up with many techniques to lessen the structural damage. But is there a way to make a building completely earthquake-proof?

Science uncovers mysteries both large and small. And then there are some discoveries that make us shake our heads. There were more than a few of those in 2012.

Why is the sky blue? What's relativity all about? If you're thinking, "something to do with light and physics and stuff," we have some short explanations for you.

On its good days, science is incredible and enlightening. On its bad days, science can be anywhere from gross to downright bizarre. What are some of science's craziest questions? (And why did anyone want to answer them?)

"Objects in mirror are closer than they appear." That little line appears so often and in so many contexts, it's almost lost all meaning -- but why is it there, and what does physics have to do with it?

In the simple rubber hand illusion, a subject is made to believe a rubber hand is in fact his own. How does this clever parlor trick work, and how could it help shed light on body-related distortions?

Nuclear plants provide the world with much of its electricity. Learn why Uranium-235 is ideal for nuclear power, in this article.

Taking into account orientation, inclination, weather, electricity demands and voltage will help you figure out whether solar panels will be efficient on your house. Learn whether solar panels will be efficient on your house in this article.

Statements we know to be true: There's a lot of pet poop in the world, and there has to be a better way to handle it. So, we're asking you, inventive readers, to get your hands dirty and send us your ideas for a better litter box.

No really, can you? Sure, there are lots of chairs out there. Some rock. Some roll. Some recline. Some remain so crazy modern that we're afraid to direct our keisters onto their serious coolness. How you would change this staple of sedentary life?

You may do some of your best thinking on the can, but we assume you're not thinking too much about the toilet itself. We at HowStuffWorks.com think you should be, and so we're challenging you to build a better toilet. What's your bright idea, reader?

We humans like to think we're so technologically advanced, yet mice constantly prove us wrong, handily evading our efforts to trap them. So we at HowStuffWorks.com are asking you to devise a better mousetrap. Isn't it about time mice learned how advanced humans really are?

You've set the table at least once in your life, right? Have you ever wondered why we need all that silverware? And so we challenge you, inventive, fork-wielding readers, to come up with a design for the master fork, the one that will put all other utensils to (stainless) shame. What's your idea?

Gravity dictates the structure of the universe, from the way cosmic bodies form to the way they orbit more massive planets or stars. Has it always played such a starring role in our cosmic history?

Gravity is great, but if we could figure out how to selectively reduce its effects, we could cut the energy demands of travel and transportation. Don't cheaper airline tickets sound pretty good?
