Even though the growth of young children in the Preoperational stage of development has slowed down a bit compared to infancy, early childhood is still a time of tremendous physical changes. During this period, children's bodies change proportions and they start to look more like adults than babies. Physical growth slows down between five and eight years of age, while body proportions and motor skills become more refined. Physical changes in early childhood are accompanied by rapid changes in the child's cognitive and language development.

Circuit, cell, bulb, switch... Find out about the electrical terminology your primary-school child will be using in the classroom and try some hands-on activities to support learning about electricity at home.
Electricity can be created in a variety of ways such as:
- burning fossil fuels (oil, gas, coal) at power stations,
- using wind power generated by wind turbines,
- using solar power generated by the sun,
- using water power (sometimes called hydropower) generated by running or falling water.
Electricity is transported to our homes, schools and places of work through wires and cables.
Electricity can also be stored in batteries (sometimes called cells).

A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.
For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.
Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.

Due to the stable configuration, they do not accept an electron and hence they have large positive electron gain enthalpy.
An electron has to enter the next higher principal quantum level which leads to a very unstable electronic configuration.
