VELCRO® fasteners are pretty cool, but what would you think if the idea came from living things? Jessi and Squeaks talk about the sticky seeds that inspired them!

Hank and Dr. Rebecca Bendick talk about her work in the science of earthquake forecasting, and then Jessi joins the show to show off Sandy the sand boa!

In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons...

In this video Paul Andersen explains how a vector field shows the distribution of vector quantities. In AP Physics 1 student should be able to map and understand gravitational vector fields. In AP Physics 2 students should be able to...

Be careful with your wool. Unless you want a nice piece of felt with some holes in it.

Sabrina gets a new set in this episode of Crash Course Kids. Do you want to be an astronaut? Would you like to someday walk on the moon? Well, you better learn a little about gravity so you can escape from Earth and head into space....

Marie Tharp's topographical maps increased our understanding of both the ocean floor and the processes that move the earth's crust.

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

In this edition of IDTIMWYTIM, Hank addresses the so-called centrifugal force, and explains why you really mean centripetal force.

Mr. Andersen shows you how to sink leaf chads in preparation for the AP Biology photosynthesis lab. An empty syringe is used to remove gas from the leaves before the lab. As the chloroplasts absorb light they produce oxygen bubbles...

In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V...

In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

Paul Andersen shows you how to find stomata in a dicot and monocot leaf using finger nail polish and transparent tape. A microscope is required to actually see the stomata.

Sometimes science can look a lot like magic! This week, Jessi will show you how to make a balloon stick to the wall; no tape required! Stick around to learn how she did it and the science that makes the trick work! Abracadabra!

Jessi and Squeaks are at the fair, and Jessi is excited to go on the roller coaster! But before they get on, Squeaks wants to know how roller coasters work.

Want to learn how to make a super secret hide-out? Jessi shows you how a bedsheet, some books -- and a little bit of science -- can be used to make an awesome fort!

We owe a lot to our moon. Beautiful moonlit walks, higher tides, and regular seasons - all are made possible by our little rocky friend. But what would happen if we picked up a second moon?

Paul Andersen explains how physical systems remain stable and unstable over time. The sum total of interactions acting on the system determine its stability. Feedback loops are used to maintain stability but require energy. If the...

A bug in the superconductor system has trapped your team in 11 separate dimensions. Can you get them back home safely? -- It was a normal Tuesday at the superconductor, until a bug in the system caused your team to be trapped in 11...

In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the...

Learn how to build a pillow fort with the help of the force called compression. Just save some room for us!

Jessi and Squeaks are working on an experiment: Making an ordinary magnet float in the air!

When people travel a long distance, they'll usually use a map. But there are lots of animals that travel really long distances, too, and they can't use maps... so how do they not get lost? Our friend Dr. Turtleman...

Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.
