Happy Earth Day!

Today is Earth Day! We spend this day celebrating Earth, raising awareness of things threatening the planet, and learning how to fix those problems! This year’s theme is plastic pollution and the threat it poses to humans and other life. Plastics can be very useful, but the huge amount that is discarded incorrectly and dangerously…

Supernovas!

Believe it or not, supernovas have been known to humans for thousands of years. That’s not to say that ancient civilizations knew exactly what was happening when they saw them, but they were witnesses to some of the most powerful events in our universe. When certain stars reach the end of their lifetime, they explode…

Bernoulli’s Principle

Daniel Bernoulli was a Swiss mathematician and physicist in the mid-1700s. He excelled in the fields of statistics and probability, but also was influential in applying mathematics to physical mechanics. Particularly, he is known for his work in fluid dynamics, now known as Bernoulli’s Principle. Most simply, Bernoulli’s Principle is a derivation of the conservation…

Pluto: Planet or NOT!

While Pluto is no longer a full-sized planet, it still has many properties that we care to learn about. It’s still the largest object in the Kuiper Belt, and by volume it’s the largest of the dwarf planets in our solar system. And its unprecedented popularity has cemented itself into the hearts of the public,…

Bubble Hurricanes

CAUTION: This experiment uses a hot plate. Please use adult supervision if attempting to recreate. Bubbles are a great resource for fun and physics. They provide interesting insight for optimization and can even be used as models for atmospheres. Scientists are able to use bubbles as models for the atmosphere because they are very thin…

Can you Freeze Antifreeze?

CAUTION: Antifreeze is a very powerful chemical that, if ingested, can cause serious illness or death. Do not attempt to use it without adult supervision. All appropriate safety precautions have been taken for the filming of this video. If you are from a colder part of the world, then you know how important antifreeze is….

How to Supercool Water

Water is usually pretty predictable. At standard pressures it will boil at 100˚C and freeze at 0˚C. However, under special circumstances it might surprise you. Dihydrogen monoxide can become supercooled, dropping below 0˚C while maintaining the liquid phase of matter. Here’s how: Acquire distilled or purified water. Fill an empty bottle with tap water (this…

The Coolest Molecules

CAUTION: This experiment uses dry ice (-109˚F) and liquid nitrogen (-321˚F). Proper safety equipment should always be used when handling these substances. Physics tells us that pressure, volume and temperature are all linked when talking about gases. So what does this have to do with solid carbon dioxide (dry ice) and liquid nitrogen? When dry…

The Space Between Planets

Have you ever really sat down to think about how much space there is in the universe? It’s pretty inconceivable, but there are some useful tools that can help put things in perspective. You’ve already seen a scale model of our solar system by mass, so here is a model of the space between our…

Free Energy or Toy

Electricity is one of the most useful discoveries of our relatively recent history. It lights the rooms we hang out in, give power to some vehicles and allows for communication across vast distances. In 1800, Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity so he constructed the voltaic pile (an early…

WELCOME TO OUR ASTROCAMP BLOG

We would like to thank you for visiting our blog. AstroCamp is a hands-on physical science program with an emphasis on astronomy and space exploration. Our classes and activities are designed to inspire students toward future success in their academic and personal pursuits. This blog is intended to provide you with up-to-date news and information about our camp programs, as well as current science and astronomical happenings. This blog has been created by our staff who have at least a Bachelors Degree in Physics or Astronomy, however it is not uncommon for them to have a Masters Degree or PhD. We encourage you to also follow us on Facebook, Instagram, Google+, Twitter, and Vine to see even more of our interesting science, space and astronomy information. Feel free to leave comments, questions, or share our blog with others. Please visit www.astrocampschool.org for additional information. Happy Reading!
