This video is a lesson on the physical changes that occur in matter as its internal energy increases. The video describes how the physical state of matter changes as it is heated, from a solid with particles in fixed positions to a...

In this video we will learn all about the States of Matter for Kids. The 3 states of matter are solids, Liquids and Gasses. Have you ever asked yourself "What is a solid?", "What is a liquid?", or "What is a Gas?" Well if you have, we've...

Сhanging States of Matter | Kids Academy Helping young kids comprehend the three basic states of matter is an important part of building a solid foundation for the more complex physical science lessons. There are 3 states of matter: A...

Learn the basics about plasma - the fourth state of matter, when learning about properties of matter. When ice is sufficiently heated, it melts to form water. It has therefore undergone a change of state – from a solid to a liquid....

This lesson will reveal the rules for writing the names and chemical formulae of ionic compounds, by balancing charges and using the cross method.<br/>
Definitions included: ionic compound, binary ionic compound, oxidation state

This lesson will introduce the rules for writing the names and chemical formulae of non-metal anions and metal cations, including metals with multiple positive oxidation states.

Definitions included: compound, cation, anion, IUPAC,...

This lesson will uncover the rules for writing the names and chemical formulae of polyatomic ions and ionic compounds.<br/>
Definitions included: monoatomic ion, polyatomic ion

The pirates are off to climb a mountain! This hiking trip is tougher than studying for a Chemistry exam! Let’s hope they didn’t skip leg day. This lesson will continue exploring separation techniques based on the physical property of...

But why is the rum gone? Don’t worry, pirates. Long Jane Silver is refilling the rum barrels. Elsewhere, Blackbeard and Cookie the Chef have a showdown. Who is the best separator of seawater across the seven seas? This lesson will...

Water can either be a solid, a liquid or a gas. How does matter change state? Chemistry - Atoms And Bonding - Learning Points. Ice, liquid water and steam all consist of exactly the same molecules. Evaporation occurs when the temperature...

This video explores how adjectives function in sentences, focusing on their placement after verbs. Using examples like the colors of the American flag and the description of a hat, the lesson explains how adjectives can follow verbs to...

Chemical equation shows the overall chemical change of reactants into products. It's a bit like a detailed cooking recipe, but where all the ingredients and all the products are written down, even the ones you can't necessarily see. The...

This lesson will discuss the rules for writing the names and chemical formulae of covalent molecules and covalent networks. Definitions included: compound, ionic compound, covalent compound, covalent bond, electronegativity, molecular...

The identity and chemical properties of any atom are determined by the number of protons in its nucleus. As atoms get bigger and heavier, the nuclei get bigger and heavier and the protons need a “nuclear glue” to help hold them together....

Mandatory lockdowns, quarantines and shelter-in-place orders meant to contain COVID-19 have created a shadow pandemic of domestic abuse, says physician Kemi DaSilva-Ibru. Sharing alarming statistics on the rise of gender-based violence...

What is the difference between solids, liquids and gases? How does each state behave? Chemistry - Atoms And Bonding - Learning Points. The kinetic theory of matter states that particles are in constant motion and there are forces of...

Join us as we continue our close analysis of T.S. Eliot’s ‘The Love Song of J. Alfred Prufrock’. In this lesson we’ll look at lines 70-86 which reveal Prufrock’s existential angst. This part of the poem contains some of the most famous...

This is a science lesson in which the relationship between the pressure and temperature of a gas at a fixed volume is investigated. The video uses visual aids to demonstrate how particles with kinetic energy collide with container walls...

Dasha Navalnaya is the daughter of Alexey Navalny, the politician and leader of the Russian opposition to Vladimir Putin. Sharing the story of her father's poisoning, persecution and current imprisonment, she details what it was like...

It's a weird time to be alive. A pandemic is sweeping the world and life as we know it has gone through a seismic shift in a matter of weeks. But this isn't the first time humans have encountered an epidemic. Today, Danielle (from the...
