In science we use models to represent the world around us. The particle model is essential in understand how 'stuff' behaves and everything in chemistry!

Choose your topic:

• Density [FREE] - The amount of 'stuff' in a given space

​​

• Specific Heat Capacity [FREE] - Linked to the thermal energy stored by an object 

​

• Heating and Cooling - The latent heat of a substance and the curves we can plot

​

• The Particle Model [FREE] - This explains a lot

​

• States of Matter - Solids, liquids and gases, and changing from one to another

​

• Gases - How particles cause pressure and how pressure and temperature are related  

​

• Gases  - How pressure and volume are related

​

• Springs - Stretching, bending and compressing elastic and inelastic objects

​

•  Pressure  - In fluids this causes a force at right angles to a surface 

​

•  Upthrust  - The force on a submerged object explained

​

•  The Earth's Atmosphere  - The thin layer of air that surrounds the Earth ​

​

•  Our Solar System  - Our home in the universe and the bodies that exist within it

​

•  Stars  - Their life cycle, from birth to death and beyond 

​

•  Orbits and Gravity  - The ultimate force that allows planets and other objects to remain in orbit ​

​

•  The Universe  - This is about literally everything there is
