SCIENCE 101 REFRESHER

What is matter?

Matter (scientifically speaking) is the everything in the universe that is made of atoms. This includes every star in the sky, every planet, everything on Earth, including yourself.

What makes matter special?

In the entire observable universe, scientists estimate this kind of matter makes up only about 5% of the total content. The remaining 95% consists of two mysterious components that we cannot directly observe: dark energy and dark matter.

Of the 5% that we can observe, practically all of it is out of human reach, spread across the cosmos to form every nebula, planet, and star. Although Earth's matter represents an extremely small portion of the universe, it is still brimming with amazing things.

If this much wonder is possible on our speck of a planet, imagine what else could be possible in the universe.

WHAT TO EXPECT

Every month's box has all-new items, but here's some of the common types of items to expect. Think of these like personal museum exhibits.

Museum-Grade Fossils

Fossils are the rocky remains of previous lifeforms that called this planet home millions to billions of years before we came along. We source our fossils from the most trusted experts and paleontologists in the field.

Start your personal museum of natural history.

Historic Artifacts

Artifacts are like human-made fossils—objects that were created by people doing incredible scientific things. Our artifacts go through a tedious process of provenance verification and expert authentication.

By preserving these relics, you're creating a record of our species' achievements.

Exotic Rocks & Minerals

Our species made it's first big leap into the Stone Age when we discovered we could make useful stuff with rocks—and we've been hooked on them since.

Learn about the science-based properties and applications of natural rocks, crystals, and minerals.

Meteorites

These fragments of other worlds ended up colliding with our speck of a planet after drifting through the immense void of the universe.

Meteorites are among the most precious items we feature, which is why we have each of our meteorites fully analyzed, authenticated, and classified.

FAQ

Will I receive repeat items?

Most subscribers will never get a repeat item. Each Matter box is unique, packed with scientific stuff you haven't seen before.

Occasionally we revisit a particularly amazing item, but we'll only repeat an item if it's been at least 3 years.

How many items will be in my box?

To ensure we get a varied mix of types of items, we guarantee a total value of $60+ in each box rather than a specific quantity of items.

Historically, our boxes have ranged from 2–8 items, but each of these boxes had a similar total value.

Do you offer educational discounts?

Yes, we do! We're all about spreading the love for science, and we understand that schools and teachers (and students) have tight budgets. That's why we offer special educational discounts to help bring our Matter boxes into your classrooms or learning programs.

These boxes are perfect for sparking students' curiosity and complementing your science curriculum.

Apply for educational discounts here, or send us a purchase order from your school. Let's make science exciting and accessible for your learners!

If your lab or company produces a scientific item, or if our organizations' missions align, we would love to explore collaboration. Whether you're a burgeoning start-up or an established industry leader, we're open to a range of partnerships that drive science forward.

Past collaborations have included sponsorships, sourcing custom items, and even curating themed boxes.
