Unit Summary:

•

•

•

. Ecology This term, coined by E. Haeckel in 1866, describes the study of the interrelationships between organisms and their surrounding, outer world; the study of animals and plants in relation to each other and to their habitats. Life forms, including man, are intimately linked with their environment. Production ecology, or community ecology ’Environmental science is an expression encompassing the wide range of scientific disciplines that need to be brought together to understand and manage the natural environment and the many interactions among physical, chemical, and biological components Photosynthesis is arguably the most important biological process on earth. By liberating oxygen and consuming carbon dioxide, it has transformed the world into the hospitable environment we know today. Directly or indirectly, photosynthesis fills all of our food requirements and many of our needs for fiber and building materials.

Subject area: Photosynthesis

Learning Outcomes in terms of specific objectives:

•

The overall objective:

• •

Understand that ENERGY can be transformed from one form to another. Know that energy exist in two forms; free energy - available for doing work or as heat a form unavailable for doing work. Appreciate that the Sun provides most of the energy needed for life on Earth. Explain why photosynthesis is so important to energy and material flow for life on earth. Know why plants tend to be green in appearance. Understand that photosynthesis is a two fold process composed of the Describe noncyclic photophosphorelation of photosynthesis. Procedures:

• • • • • •

• •

Introduction of the lesson by teacher through detailed reading listening and discussion the teacher opens the unit by introducing question. How can we lran form our past? This is followed by introduction on questions What is the photosynthesis?

•

A reading of the lesson is undertaken Difficult word. Phrases are explained. Student listen to productions of word form the unit and their correct grammatical usage. The technique role play is used to highlight the content of the lesson and promote understanding of its ramification in the contemporary world. The teacher presents the following situation to the students. In order to study the absorbance of various wavelengths of light

•

by chlorophyll, you must first separate the pigment from the leaf tissue

•

. Use your chlorophyll extract along with an ethanol blank and determine the absorbance of the chlorophyll solution at various Wavelengths

Student multimedia presentation procedure: • •

The teacher will ask the co-operation of the Computer teacher to guide the students on how to work on MS Word and MS PowerPoint. Student shall form the groups of four, each having one leader.

•

The work of finding the relevant pictures, graphics and information, evaluating and analyzing it in the light of the topic, and finally, presenting the searched information will be distributed among the groups. Student along with the help of science teacher would decide the topics to be covered in Photosynthesis for the presentation and would be ready with the presentation, example:

1. Energy can be transformed from one form to another 2. The Sun: Main Source Of Energy For Life On Earth 3.

Light Energy Harvested by Plants & Other Photosynthetic Autotrophs.

4. The Color Of Light Seen Is The Color Not Absorbed

Student publishing procedures of brochure development using MS-PUBLISHER

Student will create newsletter Photosynthesis in the plant life structure. Approximate Time Needed:

6 Weeks: approx. 13 computer period and 9 science class period. Prerequisite Skills:

The student should have read the chapter on Photosynthesis thoroughly and attended all the lectures. The student should have a fair operating knowledge of computers. The student should know to locate the information and pictures from internet and digital resources.
