EYES • We have two eyes. • Eyes are the sensory organs. • We can see through eyes with the help of light. • Eyes have eye balls. • Our eyes are protected by the eye lids, eyelashes and eyebrows. • The eyebrows prevent water from running to the eyes. • The eyelids can open and close the eyes to protect from too much light. • The eyelashes blocked the dust and insects. • Cornea is a transparent covering in our eyes. It permits light to enter our eyes. • The iris is colourful part of our eyes. • Iris control the amount of light entering the eyes. • Pupil is the black opening in the middle of the eye. • The tears from watering eyes helps to protect our eyes. • Keep your eyes clean and moist.

Soil formation

There are four main soil forming factors.They are
*parent material
*climate
*living things
*time
Parent material
Parent material is the substance from which the soil is formed.
Parent materials could be bedrock, organic mterials or old soil surface.
For example the parent matreial of white sand (Dhonveli)mainly corals.
Climate
Climate refers to the average weather conditions over along period of time for a given area. For example the climate of Maldives is Iruvai moosun is mostly warm and humid with occasional rain.
Soil vary depending on the cimate.
Climatic factors that affect soil are
*Temperature
*wind
*Rain
Living things
All plants and animals living in or on the soil can affect soil formation.When these organisms die their remains become organic materials which improve the soil. For example, Earthworms help to decompose(breakdown)waste materials. They also help in the mixing the materials in the soil.
Time
Soil takes years to form. Therefore to keep soil fertile it is important to look after the soil properly.

Agriculture

Maldives has a territorial area of about 9000square kilometers.Of this about 99% is water while the remaining 1% is land. Due to the lack of land space large scale agricultural activities are not practiced in the Maldives.Nearly 95% of thecountry's demand for food is met through imports.
However many grow vegetable and fruit trees within their household compound.Some crops grow in the Maldives include: Brinjal, Tomato, Chillie,Bitter gourd,Breadfruit, Pomegranate,Coconut, Banana, Lemon.

Recent trends in agriculture
In recent years,some farmers and companies have undertaken the growing of fruits and vegetables on a more commercial scale. This change is due to the development of regular market for agricultre and perishable products, both in Male' and in the tourist industry.
Hydroponics
Hydroponics system are becoming more popula in many of the islands in Maldives.In these systems nutrients are circulated in PVC pipe system.
Answer the following questions.
1.Define the following terms.
Hydoponics, Agriculture, Nutrients,
2.Why large scale agriculture is not practiced in Maldives?
3.List some of the crops that are grown in the Maldives?
4.Why imported fruits and vegetables more expensive than those grown in islands?
5.What can we do to reduce te cost of food?
6.Explain how to make compost at home?

Growth

All living things grow.What were you like when you were young? What will you like now?


Plants make ther own food using minerals and salts from the soil,sunlight,water and a gas called carbon dioxide from the air.
