The Magic Magnetic Tower of Magnetism!

Posted on September 8, 2018 at 2:45 PM Comments comments (0)

Magnets are…. Weird. They attract, they repel, and none of what they do can be seen with the naked eye. Even the study of magnets can get confusing as it has been tied in with electrical studies for a long time, yet also recognized as its own field of study. Though magnets may be a bit perplexing, they are an integral part of a lot of today’s technology. Common items, such as debit cards or CDs rely on magnetic technology. On the flip side, we also use magnets in very uncommon and...

Dirty water? Clean it up by building a water filter!

Posted on August 15, 2018 at 11:30 AM Comments comments (0)

Water is one of the most important things for life. More than seventy percent of our planet’s surface is covered in water and more than 55 percent of our bodies are made of water. We drink it, use it to clean ourselves, cook with it, travel on it, hunt in it, and so much more! But… what happens when we don’t have clean water to use? What if it has been polluted or poorly managed? What if a natural occurrence makes our water unusable? Even fresh spring water may not be entire...

Learn about landfills by building your own desktop model!

If you’ve ever taken the garbage out (which, who hasn’t?), you have a good idea of how nasty our trash can get. It smells gross, it looks disgusting, and tends to have all manner of horrifying fluid leaking from it. Most of us are just happy when the garbage truck comes and takes it away, because all of that nastiness is gone… right? Have you ever thought about where that truck takes our garbage though?

Most cities have some form of a waste disposal site. Some places c...

Code a code with a binary bracelet!

Posted on March 18, 2018 at 9:05 PM Comments comments (0)

When we think of computer coding, two scenes tend to come to most people’s minds: A grungy looking hacker furiously typing away in the dead of night… OR…. A team of top programmers tossing words most of us wouldn’t understand at each other from behind computer screens. But what about the old schooler’s coding binary on older computers? Or kids coding their own video games on their phones while heading to school?

Coding isn’t always super complicated. ...

How much water is in snow?

Posted on January 15, 2018 at 12:55 AM Comments comments (0)

It’s Ohio. It’s winter… there’s been a lot of snow. With a warmup coming next weekend, we are already expecting to see quite a bit of water, and even flooding in some areas. While we know that snow is just frozen crystals of water, do we know how much water it takes to make the snowflake? That’s what we aim to discover in this super easy winter STEM project!

How much water is in my snow?

Winter STEM: Making Frost

Posted on January 12, 2018 at 9:00 PM Comments comments (0)

The winter weather is blasting here in Ohio. First we had rain, then ice, and now it’s just tons of snow. The least favorite part of many Ohioans morning routines is scraping the ice off of their cars and defrosting the windows. Ohioans of all ages know this struggle. If all of the ice and snow is on the outside of the car, why do we see ice crystals on the inside of the windows? This is called frost! You can learn how it forms with a super simple kitchen science experiment, using thing...

Lakes and rivers... under the ocean?

Posted on January 5, 2018 at 11:20 AM Comments comments (0)

I love our lakes and rivers. They can be found, at least seasonally, in almost every of the world. They are always so beautiful and majestic. A wide variety of processes can form our waterways, and support an even wider variety of life! Have you ever imagined a river existing underwater, though? No, not like in in the cartoons, but an actual flowing river! Or even a lake, complete with waves rippling across the surface? These underwater waterways exist, and are becoming a focal point of study...

Learning About Soil: Part 2 of 3

Posted on October 2, 2017 at 9:55 AM Comments comments (0)

In the first section of our three part soil science post, we learned a bit about why soil is important, soil grains, soil and soil texture. If you remember, soils can be composed of sand, silt, clay, or any combination of the three. In this next experiment, you will get a chance to better see and understand the different types of soil grains. Again, you should already have ever...

Learning about soil: Part 1 of 3

Here's a riddle for you:

I am one of your most abundant natural resources, but I can also be one of the most fragile. I am almost always under your feet, yet often overlooked. I am what this planet is named for. What am I?

If you guessed dirt or soil, good job! You got it right! If you didn’t guess correctly, it’s all the more reason to learn more about this incredible resource. Many people think of soil as just a dead...

Build your own Bristle-Bot!

Robots are awesome! This is an opinion most people would probably agree with. Although we may not be making the incredibly advanced A.I.s that we see in our favorite books, films, and television shows, we are making rather advanced robots that can perform a wide variety of tasks. There’s the walking and self-navigating robots created by companies such as Boston Dynamics, the sorting bots helping to keep the operations running smoothly at some shipping companies in China, and even tiny n...
