Winter can be a tough time for birds. Whilst we are tucked up under our blankets drinking hot chocolate, birds are out there facing the harsh conditions of winter. Although many stay in this country the hardened cold weather can put them at risk. Food is in shorter supply and if an ice frost creeps over it can harden nuts and berries and make it impossible to eat them. Birds can starve to death after three days if a frost or snow...

Chromatography – lets get some separation

When substances are mixed together it is often very difficult to separate them out and see what is included in the mixture. Chromatography is one method in which you can separate mixtures and can help  solve crimes or mystery’s. It is a method often used in forensic science! For example if someone left you a secret note and you suspected three people and they all had different pen, you could test the pens to see what colour dyes...

Making Bread – Respiration in action!

Respiration is a biological process that is fundamental to any living things. It is the process by which energy is made, so that all the chemical reactions can occur in your body. Respiration is the reaction between glucose (your food) and oxygen in the air you breathe, to produce carbon dioxide and water (waste products) and the all important ENERGY! We can see this process occurring when we make bread! You will need A mixing bowl...
