General Science Grade VIII

Students’ Learning Outcomes

·         Define Biotechnology.
·         List some biotechnological products used in daily life.
·         List general application of biotechnology in various fields.

Information for Teachers

·         Biotechnology is a large-scale industrial use of biological processes of microorganisms to make substances useful for mankind.
·         Biotechnology is the use of biological processes, organisms, or arrangements to manufacture products envisioned to increase the quality of human life.
·         In simple form, biotechnology is the use of living system (organisms) by people to make products.
·         Biotechnology uses many different sciences, such as biology, chemistry, physics, engineering, computers, and develop information technology to develop tools and products.
Concept Map
Material / Resources
Water, flour, yeast, bowl, beaker
Worm up activity
·         Brainstorm the students about asking different questions:
o   What they know about microorganisms?
(Expected response: They are used in making yogurt, cake, bread, milk, meat and medicines.)
·         Now introduce them the today’s topic “Biotechnology and its application” in which they will learn, how the scientists use the microorganisms in order to make products for human use.
Development
Activity 1
·         arrange the warm water, flour and yeast.
·         Ask the students to:
o   Mix the yeast with the flour, and add warm water to make dough.
o   Leave it for 20 minutes.
o   Then ask the students to observe this dough carefully and tell:
Ø  What is the change?
Ø  What may be the cause of this change?
·         Now explain that yeast acted upon flour dough and produces CO2 and alcohol, which made hollow cavities / pores inside the dough. This process is known as fermentation.

Sum up / Conclusion

·         Summarize the lesson; Biotechnology is a large scale industrial use biological process of microorganisms to make substances useful for mankind e.g. making of yogurt, cake, bread and medicine etc.

Assessment

·         Ask the students to write the names of the products in front of process of biotechnology given in the table:
       Application
         Products
Fermentation


Genetic engineering


Tissue culture


·         What will happen if we add yeast instead of baking soda in dough for making pizza/cake

Follow up

·         Make a list of biotechnology products.

·         Guide the students to solve the exercise problems given at end of unit/chapter of textbook.
