In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the...

Jessi's in the lab, mixing up something kind of strange: Oobleck! Come find out all about this goo that can be a solid and a liquid at the same time, and then learn how to make some for yourself!

On a cold day, sometimes people will say "I'm freezing!," even though they aren't actually frozen like ice. But there is a very special animal that can say "I'm freezing" and mean it: wood frogs! Join Jessi and Squeaks to...

In this video, students will learn about different methods of separating substances in mixtures and solutions. They will explore physical changes in matter, the properties of mixtures and solutions, and the processes of evaporation,...

The video is a lecture presentation on exothermic and endothermic reactions. The presenter explains the definitions of these reactions and demonstrates two experiments to determine whether a reaction is exothermic or endothermic. The...

Glass is made by heating sand (mostly composed of silicon dioxide) until it melts and turns into a liquid at a high temperature of around 1700° Celsius. When the molten sand is allowed to cool, it becomes an amorphous solid, featuring...

If you mix cornstarch and water (2 to 1), you will get a suspension that acts like a solid when you put a pressure on it, but then it can flow like a liquid. Perfect for messy play at any age. If you feel creative, add some food...

In this video, students learn about finding the volume of a solid and connecting it to their understanding of place value models and measuring liquid volumes. The video addresses common mistakes students make, such as confusing units and...

All cooking is science: we use chemistry and physics to steam, fry, bake, or microwave almost all of our meals. However, there are some cooking methods that delve into even deeper and stranger scientific territory.

Can you believe that you can blow up a balloon without actually blowing your own air into it!? Follow along with this super neat experiment and find out how!

Learn about energy diagrams, calculating molar heat of vaporization and fusion and molar heat of solution in this video! Transcript ______________ In this diagram we have the temperature of water in degrees celsius on the side and energy...

If you mix cornstarch and water, you will get a suspension that acts like a solid when you put pressure on it, but then it can flow like a liquid. It feels like the snow that melts away so quickly. This is perfect for messy...

Density Of Different States | Matter | Physics | FuseSchool Why is it easy to lift up a big inflated beach ball but much harder to lift a small heavy pebble? It is largely to do with density, the small pebble is more dense and the Big...

A fun song I wrote for my science classes to help introduce the concept of dissolving solids in water (salt and sugar). LYRICS: I like to dissolve things, Just like scientists like to solve things, And I’m using H2O, That’s just water,...

From cleaning supplies to pharmaceuticals, surfactants are the compounds that make your soap bubbly, your paint spread smoothly and your medication dissolve more easily. Surfactants can be found everywhere because of their unique...

Balloons are made of a stretchy rubbery material called latex – that’s a white milky liquid made of rubbery particles in water. Latex has great elasticity – it can be stretched to eight times its original length and still return to its...

"Keeping Up With Carbon" is the final episode in the six-part series "Tides of Change", exploring amazing NASA ocean science to celebrate Earth Science Week 2009.



Carbon is all around us. This unique atom is the basic...
