This fascinating program takes students on a journey through time as the history of life on Earth is explored. From the dawn of life to the existence of advanced vertebrate animals, each of the major periods of life are investigated....

Work through this practice GCSE / K12 question on atomic number, atomic mass and electronic configuration. Read the question, and hit pause if you want to try answering it yourself. Then hit play again to watch how the teacher solves it.

The video explains the process of protein synthesis, how information from DNA is used to build complex protein molecules from simpler amino acids, and how the order of bases controls the order in which amino acids are assembled,...

In this video, the presenter discusses the interaction between electromagnetic waves and charged particles. The video covers examples of radio waves interacting with electrons and how they can create alternating currents in appropriate...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

The video is about the components of blood and their functions. It starts by introducing blood as a fluid that transports substances to and from body cells. The video then describes the different components of blood, including plasma,...

When we learned about periodic trends, we learned about ionization energy. Just how much energy is required to remove an electron from an atom? What about a second electron, or a third? Let's compare a few different ionizations and see...

Scientists at Oregon Health and Science University have grown human embryos mixing genetic material from three parents. Humans possess two types of DNAs - nDNA in the cell nucleus, and mDNA in the cell mitochondria. While a baby receives...

This video explains the different stages of the cell cycle and how stem cells differentiate to form various cell types. It starts by discussing the structure of chromosomes and then moves onto describing the three stages of the cell...

Radiation and fallout in Hiroshima vs in the Chernobyl accident. Hiroshima and Chernobyl both suffered a major atomic disaster, where radioactive atoms was released. Hiroshima was nuked by the uranium fissile atomic bomb, little boy...

In this video, we're going to learn how diodes work. We're going to start by reviewing the basic properties of diodes, and then we'll move on to discuss how diodes are used in circuits. By the end of the video, you'll have a basic...

Upon viewing the Exploring the Building Blocks of Matter video series, students will be able to do the following: Understand that the quest to better understand the building blocks of matter has transpired over the past several thousand...

It explains Atomic Models - Thomson model and Rutherford atomic model.

This video explains the concept of half-life in relation to radioactive decay of isotopes. It discusses the two ways in which half-life can be defined and how the random nature of radioactive decay gives rise to the idea of half-life....

The video is a lecture on the hazards of radioactivity. It discusses the four main types of ionizing radiation (alpha particles, beta particles, gamma rays, and neutrons), how ionizing radiation can cause tissue damage in living...

We've learned about all the different types of nuclear reactions that can occur, so given this word problem, can you find the missing nuclide?

In this video we look at what the weighted average is.

We don't have to know too much physics to do chemistry, but the electron, the particle that makes all the chemistry happen, is a quantum mechanical particle, so we have to understand it just a little bit. Don't worry, no math, just...

What is an atom | Matter | Physics | FuseSchool Atoms are tiny particles that are so small they are not possible to see with the naked eye, and are only barely possible to make out with the most powerful microscopes. Everything that...

Learn the basics about Group 1, as an example of Groups in the periodic table.

This video discusses the role of electrons in bonding together individual atoms to form larger, more complex structures. The video also explains how atoms achieve stability by gaining or losing electrons to form positive or negative...

We recently discovered some Holospora infecting one of our Paramecium samples. How does that happen? How does the Holospora get in there? And how are they so successful at infecting?

Isotopes | Matter | Physics | FuseSchool The periodic table divides the world into just over one hundred ​elements​, sorted by their chemical properties. But did you know that each kind of ​atom is made up of a different combination of...

Nuclear Fission In a nuclear reactor the controlled slow release of energy is used to heat up a closed loop of coolant which passes to heat exchangers which then boil water to provide steam to turn electrical generators. The output of...
