Video Descriptions

KLRN Virtual Classroom Welcome!

ScienceU: Make Your Own Comet

What is in a comet? Some scientists call it a "dirty snowball in space". With adult supervision, Science-U campers make their own comets with a mixture of materials that might surprise you. The resulting lump makes a comet tail of melting gases when you hold it up to a lamp in a darkened room.

Chemical Reactions

Color-changing breath, chemical goo and elephant toothpaste? Explore chemical reactions and discover how hydrogen molecules break and fuse to create new compounds as evidenced by color changes, released gases, the emission of heat or light, or an altered state of matter. STEM Challenge: build bottle cars powered by a chemical reaction. Episode #0106

ScienceU: Oobleck!

Oobleck - when is a liquid not always a liquid and a solid not always a solid? When its "Oobleck"! - the solution of water and corn starch particles that change their state of matter under pressure! Make a ball of Oobleck in your hands and as soon as you stop squeezing it will run through your fingers! But walk or jump across its surface and it forms a solid bridge beneath your feet!
