UNIT 10 WEATHER AND CLIMATE

UNIT 10 WEATHER AND CLIMATE 10.1 Measuring air temperature The weather report usually shows the minimum and maximum temperatures for each day. The temperature of the air around us is measured using a room thermometer. 10.2 Humidity Humidity or relative humidity is a measure of the amount of water vapor in the air. Water vapor is water in its gaseous state. A hygrometer measures how humid or dry the air is. 10.3 Atmospheric pressure We know the present of the air because of wind and atmospheric pressure . Atmospheric pressure is the force of air pushing an area. 10.4 understanding the features of weather There are many factors that affect weather of a region. These factors are air temperature, wind speed, and direction, clouds and rainfall. Air temperature is usually higher during the day than during the night. Air temperatures change due to cloud cover and presence of rain . Air moves from an area with high pressure to an area with low pressure. Thi...

UNIT 9 ECOSYSTEM

UNIT 9 ECOSYSTEM 9.1 ECOSYSTEM Ecosystem are all the organisms living together in an area and their interaction with one another as well as their environment. An organism habitat are made up of A biotic (non-living) and B iotic (living) factors. Some A biotic factors are l ight, temperature and air. Sunlight is used by plant to make photosynthesis. The temperature of a habitat determine s the kinds of organisms living there. Plants and animals need oxygen for respiration all the time. Some B iotic factors are man and other animals, plants, bacteria and fungi. Human beings may change the environment through air, land, and water pollution. Animals have to compete with one another for food. Some bacteria and fungi can cause diseases. Plants have to compete with other plants for sunlight, water, and mineral salts from the soils. 9.2 MAKING A MODEL OF ECOSYSTEM 9.3 FACTORS THAT AFFECT THE ORGANISM The amount of sunlight affect the ...

UNIT 8 REPRODUCING IN FLOWERING PLANT

UNIT 8 REPRODUCING   IN FLOWERING   PLANT 8.1 PARTS OF FLOWER The main parts of flower are female and male parts. The female parts of flower are Stigma, Style, and Ovary.   The male parts of a flower are anther or pollen head, filament or stalk.   8.2 POLLINATION Pollination: the transfer of pollen from the anther to the stigma of a flower. Can come from same flower or different flower. Flower that are pollinated by insects and birds are usually large and colorful. 8.3  FERTILIZATION Pollen grains landed on stigma and produce pollen tube. The tube grows down from stigma to the ovary which contain ovules.  Inside each ovule is the egg cell. The pollen tubes guides male reproductive cells to the ovules and fuse with the egg cells. 8.4 FROM FLOWER TO FRUIT The flower wither and drop off except for the ovary.  The ovules start developing into seed. The ovary enlarges and b...

Unit 8 Changes In The Environment

Unit 8 Changes In The Environment 8.1 slow environmental changes Some slow environmental changes: -          -   -  Soil erosion : the loss of the top layer of soil overtime. -    -  Global warming : the rise in temperature on the earth. -    -  Weathering : the breakdown of stones, rocks, and minerals over time. -    -  Depletion of ozone layer : the ozone layer slowly become thinner due to the result of Chlorofluorocarbons ( CFCs ). CFCs gas produce by air-conditioner, refrigerators , Styrofoam packaging, aerosol sprays. Causes of slow environmental changes - Deforestation : clearing trees by cutting or burning - Burning fuels : when fuels are burnt, carbon dioxide and other harmful gases are released to the air. 8.2 Rapid environmental changes Some examples of rapid environmental changes: Landslide : movement of mass of rock or earth down a slope. Volcanic e...

UNIT 9 ECOSYSTEMS

UNIT 9 ECOSYSTEMS 9.1 Animal around Us Community : all different population and organism that live together in a habitat Ecosystem : an interaction between community and non-living environment. Example : in a garden, population of plants, bees, and butterflies make up a community interacts with sunlight, air, water, and soil. 9.2 examples of ecosystems Ecosystem can be terrestrial and aquatic. Examples of terrestrial ecosystem are: T ropical  rain forest : warm and receive high rainfall throughout the year. Divided into four layer. Some animal that can be found are monkey, eagle, butterfly, toucan, slot, jaguar, tree frog, fungus, giant  anteater. Savannas : type of grassland that have wet and dry seasons. Some have all trees and short shrubs. Some organism that can be found are acacia and baobab tree, elephants, hippopotamus, giraffes, lion, and cheetah. Desserts: very dry places that receive very little rainfall every year. Very hot d...

UNIT 7 REPRODUCTION

UNIT 7 REPRODUCTION 7.1 Reproduction Living things can produce offspring through asexual and sexual reproduction. Asexual reproduction require one parent. The young produced a clone of the parent. Several asexual reproduction method in animals: Budding, formation of internal buds,  fragmentation, regeneration. Sexual reproduction require two organism: a male and a female. Mature male organism produce reproductive cell called sperm cell . Mature female produce egg . Sperm cell and egg fuse and develop into the young. 7.2 How human life begins Sperm cell meets an egg and fuse. The fusion between male and female reproductive cells is called fertilization . Many sperm cells reach the egg, but only one sperm cell can fertilize the egg. The fertilized egg starts to form more cells. It attaches to the wall of mother womb and continue to develop and grow. The developing baby draws nutrients from mother’s blood through the umbilical cord . About nine month...
