By 2050, the world’s population will reach nearly 10 billion, so we’ll need to produce twice as much food. New farming technologies like robot harvesters, drones, sensors, lab-grown meat, and genetically modified crops are helping...

Satellite images show how fast the Earth is changing due to things like melting glaciers, wildfires, dams, and growing cities. These changes can affect people’s lives, such as forcing them to move or losing access to water and land....

You are truly fluent in English if you can understand English humour. In this lesson we will look at wordplay (puns), one-liners, satire, knock knock jokes, and sarcasm. If you have any jokes you would like to share, please write it in...

After numerous stays on the island of Puerto Rico, Dr. Boyd finally saw the elusive Coqui frog!

Learn about this little-known Black inventor who had an impact on virtually anyone who has opened a door.

In celebration of Black History Month, learn about this pioneer of modern-day GPS systems, Dr. Gladys Mae West.

Discover the truth about lattice energy and why size really matters in ionic bonds. In this video, you'll learn what lattice energy is, why it's crucial in chemistry, and the factors that influence its strength. Understand how the size...

Empirical and Molecular Formulas are used to help scientist determine the identity of unknown substances. In this video, we discuss what empirical and molecular formulas are, what the difference is between them and how to find/calculate...

In this video, you'll learn the fundamentals of gas laws and how they describe the behavior of gas molecules. Students will gain a clear understanding of key variables—pressure, volume, temperature, and moles—and their significance in...

Boyles' Law Calculations are EASY! Boyles' Law tells us that there is an inverse relationship between the pressure and volume of a gas. But what does that mean? In this video, we cover Boyles' Law in detail and also go over how to...

Charles's Law tells us that there is a direct relationship between the volume and temperature of a gas at constant pressure! In this video we cover the background information needed to understand Charles's Law as well as the formula to...

Gay Lussac's Law is a gas law that explains the relationship between the temperature and pressure of a gas at constant volume. In this video, we explain Gay Lussac's Law with real life examples and work through specific gas law practice...

The Combined Gas Law is a useful gas law when explaining the behavior of a gas where pressure, volume and temperature are all involved. In this video, we show you an easy way to solve combined gas law problems!

The Ideal Gas Law helps describe the behavior of an ideal gas. In this video we cover what an ideal gas is and how to use the formulae PV=nRT to solve Ideal Gas Law Problems!

Dava Sobel, known for her work on astronomy, decided to explore the life of Marie Curie—despite Curie not being an astronomer. To do so, Sobel had to learn chemistry, which she found challenging. She turned to three influential high...

When we discussed basic information regarding homogeneous and heterogeneous catalysis, we mentioned hydrogenation of alkenes in both of these contexts. Now let's get more specific and describe the mechanism of this precise catalysis in...

Transition metals are elements in the d orbital. The reason these are unique is that they do not have 1 set charge they become when they become an ion like elements in the s and p orbital. Elements in the d orbital, or our transition...

In this video, we'll be looking at the different types of notation and how they're used to represent the atomic structure of elements. We'll be using both symbolic and isotope notation to show the different properties of the...

While While the Bohr model of the atom is not the most accurate model we have today, it can help up show a lot of valuable information about the atom. Bohr models can show the protons and neutrons in the nucleus along with the number of...

A covalent compound forms when electrons are shared and this will happen when you have 2 nonmetals, or 2 anions, bonding together. The reason these elements share their electrons is because they have a small difference in...
