In this video viewers will learn that heat of fusion is equal to the amount of heat that must be added or given off to melt or freeze one gram or kilogram of a substance and it’s expressed J/g or J/kg. Students will learn what units are...

The video explains two processes involving atomic nuclei that release large amounts of energy - nuclear fission and nuclear fusion. The video explains how uranium 235 can be made to undergo nuclear fission and also discusses the concept...

Energy Sources | Energy | Physics | FuseSchool There are many different sources of energy, how many can you name? Sources of energy include burning coal, oil, gas and biomass, solar, hydroelectric, tidal, wind, muscle power, geothermal,...

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

It explains the process of fertilisation and describes how the zygote gets implanted in the uterus after fertilisation.

At the start of the 20th century scientists had a good estimate of how old the Earth was. At least several billion years of age. This led to the tricky question as to how the Sun not only generated heat and light, but how it had done...

It explains the sequence of events taking place during sexual reproduction in animals. i.e. Gametogenesis; fertilisation and embryonic development.

The video is a lecture on the topic of nuclear fusion, which involves the combination of two small nuclei to form one larger nucleus. The lecturer compares nuclear fusion with nuclear fission, which is the splitting of a nucleus into two...

This video is about the lifecycle of a star but did you know that each star starts from a cloud of dust and hydrogen gas?

In this video, we work an example problem for freezing point depression in physical chemistry.

Doodle Science teaches you high school physics in a less boring way in almost no time! GCSE Science

This video discusses what thermal energy is and describes how it is generated by radioactive decay and how it contributes to geothermal energy. Viewers will also learn about solar energy, what it is and how it is created by fusion....

This is a video that explains the two types of reproduction: sexual and asexual reproduction. The video begins with an introduction on the importance of reproduction for organisms, and then focuses on sexual reproduction. The video also...

This is an overview about the virtual school's global 'quality education for all' program. The virtual school aims to provide access to world-class education, free of charge to students around the world.

Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe...

An animation showing the life cycle of a star. Everything from the interstellar space, Interstellar clouds, pressure waves, protostars and protoplanets, the Hydrostatic equilibrium and at last the collapse of a star. Animated in virtual...
