So there is a lot to learn when it comes to the surface of the earth and its crust and core, however it’s also pretty cool! Well technically it’s extremely hot, but you get my drift. Firstly we’re going to … Read More

Carbon dioxide in the early atmosphere
The Earth’s atmosphere has changed drastically over thousands of years and here we’re going to examine the early atmosphere and the presence of carbon dioxide, The early atmosphere was made up mostly of carbon dioxide, along with smaller amounts of … Read More

Earthquakes and volcanoes
In this section we’re going to focus on earthquakes and volcanoes, both of which are related to tectonic plates. Volcanic eruptions are caused by molten rock from the inner Earth layers erupting out of the crust due to the movement … Read More

Chemistry of the atmosphere
The atmosphere on Earth is extremely complex, and there are millions of reactions taking place all the time, so there is quite a lot to learn in this section! But thankfully it’s not too complex. The early atmosphere was mainly … Read More

Organic chemistry
The bad news is that organic chemistry is kind of a big topic! So we’re going to split it up into the main topics you need to learn for GCSE, namely alkanes, alkenes and and the cracking of crude oil. … Read More

The rate and extent of chemical change
The rate or speed of a reaction can measure how much product is being formed in a specific time. The rate of a reaction can change as a result of changes in temperature, concentration, pressure and the presence of catalysts. … Read More

Energy changes
As the title would suggest, in this section we’re going to examine the role that energy plays in chemical reactions and how a reaction is able to impact energy. First thing to learn, energy cannot be made or destroyed – … Read More

Chemical changes and ions
In this section we’re going to focus on the changes that occur during chemical reactions and how this impacts an element. So to start with let’s take a look at word and symbol equations. Word equations can be less descriptive … Read More

The Earth’s core
So there is a lot to learn when it comes to the surface of the earth and its crust and core, however it’s also pretty cool (well technically it’s extremely hot) so let’s get stuck in! Firstly we’re going to … Read More
