Actvites for kids

Learning science is real pleasure. The knowledge and activity and helps you to solve the problem and increase your understanding.

Before any experiment arrange all devices or objects. Keep a wash rag always at hand. An apron is a must. Conducting experiments in a room ventilated. Insist on a peer or a guide to be around to help in case of an accident.

A simple test of photosynthesis can be observed in the growth of a plant. Keep a plant in a dark room after watering. Bring the plant to light and put a camera film on one of its leaves. Plants require sunlight to build starch. The carbon dioxide in chlorophyll in the leaves also facilitate this process. The products of photosynthesis is the release of oxygen. When the film was removed from discoloration of the area covered is obvious.


Evaporation is the explanation of the water cycle. Due to sunlight, air evaporates from the sea, condenses to form clouds and precipitates to form raindrops. That can be easily explained after boiling water in a pan,observe the cover, it condenses to water which falls from the boat. Thus, the water cycle is clearly explained.

Static electricity is well known by combing hair. plastic combs acquire negative charge and hair acquires positive charge. This causes repulsion, and hence sometimes using a hairdryer results in single strands.

Germination is deemed in the best summer holidays. The growth of the plant from a seed is certainly a pleasure to watch. Water seeds buried in the ground. Water activates growth, the seed breaks and roots emerge. Roots dig into the soil and further form moreroots. The plant moves towards sunlight and soon becomes a tree with leaves and fruit.

These kind of activites can keep young teenagers busy throughout their summer vacatons!!!
