English Lesson Plan
Previous knowledge :
In order to check previous knowledge of students, teacher will ask questions such as, I will ask simple question about the forests, diversity of trees, diversity of species are discuss with students for check the previous knowledge.
Announcing the topic :
Dear students, Today we are going to learn about “forest” Presentation: teacher Will deliver lecture on A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world incorporating factors such as tree density, tree height, land use, legal standing and ecological function.
The Food and Agriculture Organization defines a forest as land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ. It does not include land that is predominantly under agricultural or urban land use. Using this definition found that forests covered 4.06 billion hectares or approximately 31 percent of the global land area in but are not equally distributed around the globe.
Forests are the dominant terrestrial ecosystem of Earth and are distributed around the globe. More than half of the worlds forests are found in only five countries Brazil, Canada, China, Russian Federation and United States of America. The largest part of the forest 45 percent is found in the tropical domain followed by the boreal temperate and subtropical domains. Forests account for 75% of the gross primary production of the Earths biosphere and contain 80% of the Earths plant biomass.
Net primary production is estimated at 21.9 gigatons carbon per year for tropical forests 8.1 for temperate forests and 2.6 for boreal forests. Forests at different latitudes and elevations and with different precipitation and evapotranspiration form distinctly different biomes boreal forests around the North Pole tropical moist forests and tropical dry forests around the Equator and temperate forests at the middle latitudes.
Higher elevation areas tend to support forests similar to those at higher latitudes, and amount of precipitation also affects forest composition. Almost half the forest area 49 percent is relatively intact while 9 percent is found in fragments with little or no connectivity.
Tropical rainforests and boreal coniferous forests are the least fragmented whereas subtropical dry forest and temperate oceanic forests are among the most fragmented.
Summative evaluation:
At the end of this lesson I will discuss the biomass, diversity and temperature of the forest with students Students to develop and apply problem-solving and research skills ? A well trained teacher deliver lesson plans but it is now responsibility of students apply their skills to prove problem solving.
it depends on students ablity how step by step questioning which they missed or not possible to understand ,here also main Factor involve mental approach . A lesson complete guide to students understand and prepare themselves for exam and research work also
