Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

This video explains the various ways in which waste can be classified, such as solid, liquid, gaseous, hazardous, biodegradable, and non-biodegradable. It also introduces the concept of e-waste and its proper management.

A video entitled “Classifying Matter” which discusses the physical characteristics of matter, including how those characteristics can be used to understand, study, and experiment on all states of matter.

Imperfections in solids are irregularities or deviations from the ideal arrangement of atoms or molecules in a crystalline solid structure. These defects can occur during the crystallization process when the rate of crystal formation is...

Miss Palomine explains the meaning of categorizing. Then, with a list of objects, she demonstrates how many ways they can be categorized or classified.

In this video your students and kids will learn how animals are classified into different groups. Classification breaks very large groups down into smaller groups. This makes them easier to be studied. Scientists classify animals, plants...

In this first and second grade video for kids learn about solid and liquid properties and how to classify matter as either solid or liquid. While we...

It's snowing and Mister Brown needs to go put some salt on the Fort's front steps. But Squeaks wants to know, why do we put salt on icy sidewalks?

Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is...

Upon viewing the Rocks video series, students will be able to do the following: Define rock as a solid, naturally-occurring mixture of minerals. Define minerals as solids with a definite chemical composition and crystal structure....

It talks about waste/garbage, identifies solid and liquid wastes and classifies them as biodegradable and non-biodegradable.

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

Introducing the liquids whose behaviours seem to defy the accepted states of matter. What are they and why don't they behave as we predict? Chemistry - Atoms And Bonding - Learning Points. Newtonian liquids take the shape of their...

In this lesson, students will learn how to write and graph equations of proportional relationships in the form of direct variations. They will also identify the constant proportionality from an equation and learn how to use it to graph...

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...

Jessi and Squeaks found a branch growing what looked like white hair! So they brought the branch back to the Fort to run some tests and found out that it isn't hair at all... it's ice!
