  2. What Happens When Polar Ice Caps Melt?

    Fears surrounding climate change are growing, and for good reason. Small changes in the concentration of greenhouse gases can trigger an avalanche of events that will change life on Earth as we know it. One big concern relating to climate change is melting polar ice caps, which isn’t an...
  3. What is Sustainable Fashion?

    Back in the day, clothes consisted of whatever could be pieced together in nature. Now, we have fashion that ranges from simple everyday wear to extravagant couture that could only be worn on a runway. No matter what’s being made, though, it all requires materials. These materials are grown...
  4. How To How to Use Less Plastic

    The convenience of plastic has led to its widespread, and sometimes excessive, use. Grocery shopping often makes this blatantly apparent, when you’re left with more plastic to toss than food you bought. It’s almost hard to avoid, but it’s not impossible. If you’re looking for ways to be more...
  5. Are Electric Cars More Environmentally Friendly?

    There’s a lot that we can do to make our lives a little more environmentally friendly. Recycling, using less water, buying fewer single use plastics...the list goes on.

  6. What Causes a Chemical Reaction?

    Chemical reactions take place all the time. Iron rusting is a chemical reaction. Burning wood is a chemical reaction. There are even a whole bunch going on in your body right now! The universe runs on chemical reactions, but what’s the catalyst? Here’s what causes chemical reactions: 1...
  7. What Plant is the Most Toxic?

    Nature comes up with a whole host of ways to kill. Predators grow scary teeth and claws, and prey develop effective defense mechanisms. Plants are no exception and are just as capable of killing you as a predatory animal. They’re more subtle about it, though. Toxic plants abound, but it’s worth...
  8. How Do Plant Species Go Extinct?

    Extinctions tend to happen every few million or so years. These extinctions don’t just happen to animals, but plants as well. It shouldn’t be surprising, given that plants are living organisms that adapt to their environment. Changes that affect a plant’s ability to survive and/or reproduce can...
  9. What Causes Lightning?

    Dangerous and beautiful are two words that come to mind when thinking about lightning.

We now know the science behind...
  10. How Are Pharmaceutical Drugs Made?

    Pick an ailment, and there’s probably a pharmaceutical drug out there to cure it or at least relieve the symptoms. It’s kind of like the medical world’s “There’s an app for that.” We appreciate what these medications can do for us, but rarely do we think about what goes into creating them...
  11. Why Is the Equator Warmer?

    When the winter chill sets in and your hometown becomes a dull, gray, dreary place, don’t you long for a warmer climate? And when you think of vacation spots, islands in the Caribbean are probably close to the top of the list. In fact, any prime vacation destination with sandy beaches and a...
  12. Why Do We Have Leap Years?

    If you were born in a leap year, you’re used to the old joke. “Congrats, you’re finally X age!” which is inevitably a much younger age than the number of years you’ve existed on this planet. But because math is tricky and so is the universe, those born on February 29th have to live out their...
  13. How are Fingerprints Left Behind When You Touch Something?

    Fans of crime shows know that evidence is everything, and something as unique as a fingerprint is often some of the best evidence to help with catching that bad guy by the end of the episode. The science in these shows is often sketchy, but the one thing they do get right is that wherever you...
  14. How To Coronavirus How To: Social Isolation vs Quarantine

    When a pandemic sweeps across the world, many people are stuck and don’t know what to do. A lot of terms get thrown around that are supposed to serve as a guide, but their meanings can be vague. To stop the spread of the virus, two ideas have been suggested and implemented: social isolation and...
  15. How Do Gene Mutations Happen?

    Our genes are what make us...us. They hold the code (literally) to who we are and who we become. Humans have between 20,000 and 25,000 genes, and these are inherited from our parents. Our genes are all the same, for the most part, except for a few which result in our unique appearances...
  16. What Animal is Our Closest Relative?

    The study of evolution is a fascinating look into the past. It’s also enlightening, as it teaches us that we’re all connected, all related. People have, both in the past and recent times, had issues accepting some conclusions of the theory of evolution, such as our close relation to “monkeys”...
  17. How Do Fault Lines Work?

    The ground we stand on is not quite as solid as we imagine it to be. It’s really made up of shifting plates that move around and smash together, like a really really slow game of bumper cars. These plates have a lot to do with how the Earth looks and acts. Fault lines are a part of this whole...
  18. How Do Galaxies Form?

    The Hubble telescope has shown us incredible sights, including an estimated 100 billion galaxies. That’s definitely not how many are out there, though. Once we have more powerful telescopes, we’ll probably see about 200 billion. So how did all those galaxies get there? How do galaxies form...

A...
  20. What’s the Farthest Object We’ve Ever Spotted?

    Peer up into the sky on a clear night away from city lights, and you’ll be able to see about 4,500 stars. That’s nothing compared to the number of stars in our galaxy alone, which is between 100 and 400 billion. The incredible technology we have has allowed us to see even beyond that into...
