It is important that the membranes around living cells are 'semi-permeable' to allow it to absorb nutrients and dispose of waste products. In this science experiment we will study the inward and outward flow of materials through the 'semi-permeable'...

'Cells' are the basic building blocks of an animal's body. These cellular building blocks are so tiny you would need about 10 000 just to cover a pinhead. There are a huge amount of different kinds of cells in...

Humans have 'stereoscopic vision', meaning that we can judge the direction and distance of an object because each of our eyes sees from a slightly different angle, resulting in a perception of depth. Similarly, because our ears are positioned...

An adult's lungs can hold about 5 litres of air when fully breathing in – How much air do you think your lungs can hold? With the following science experiment you can find out!

When we think about ants, we usually think about how troublesome they are. Ants are actually very interesting and they have a highly organized social structure and way of life. Ants are very social insects. They live in colonies...

Preservatives can be artificial chemicals developed by scientists, but many natural preservatives can also be found in your kitchen as can be seen in the following science experiment.

Green plants absorb the light and use it to break down 'chlorophyll' during 'photosynthesis' and this chemical reaction leads to the production of energy. Plants uses mainly their leaves for photosynthesis, and if a plant loses too many leaves,...

'Transpiration' is a process by which plants take back water to the atmosphere. After absorbing and retaining water from the ground through their roots, plants then release water through structures in their leaves, called 'stomata' to the atmosphere.

Pollution from various chemical sources such as laundry and other detergents, is released into the soil of the earth on a daily basis. Many of these detergents are phosphate-based and can be very damaging to freshwater, plant and animal...

In this experiment we will create a dramatic coloured fountain by using two jars of water, one with hot water and one with cold water. The hot water in the bottom jar wants to rise to be above the...
