Anu-Digital-Textbook 1 https://share.google/X1KQOqbFIOgNAMK1x    as part of BEd curriculum, we have to create a digital textbook. I selected the topic evolution. Provided the given topic in 5 chapters how life begin-the chemical journey climbing the ladder of evolution proof of the past-traces of evolution DNA speaks -molecular proof of evolution human and the future of life included pictures, activities, extended activity in the digital textbook

The given cognitive map clearly explains the concept of Plant Tissue Systems in a simple and well-organized manner. It classifies plant tissues into three major systems— epidermal, ground, and vascular —based on their structure and function. The map shows how the epidermal tissue system provides protection and includes structures like stomata, trichomes, and root hairs, while the ground tissue system performs functions such as photosynthesis, storage, and support through components like cortex and pith. It also illustrates the vascular tissue system, highlighting the role of xylem and phloem and the different types of vascular bundles. Overall, the cognitive map helps in understanding the internal organization of plants by presenting the relationships between various tissues in a clear and meaningful way.  

  Cognitive Map: Theories of Biological Evolution Biological evolution explains the gradual change in organisms over time, leading to the origin of new species.  Lamarck’s Theory of Inheritance of Acquired Characters (1809)  states that environmental changes create new needs, leading to the continuous use or disuse of organs; used organs develop while unused organs degenerate, and these acquired characters are inherited (e.g., elongation of giraffe’s neck).  Darwin’s Theory of Natural Selection  explains evolution through overproduction of offspring, struggle for existence, and variations; individuals with favorable variations survive and reproduce (“survival of the fittest”), while unfavorable variations perish, resulting in the origin of species. Natural selection may be directional, stabilizing, or disruptive.  Mutation Theory (Hugo de Vries, 1901)  states that evolution occurs due to sudden, large, heritable changes called mutations, leading to new...

  November 28 I reached school on time, signed the attendance register, and went to the allotted room. There were no special events on this day, and the routine classes continued as usual. last day of our teaching practice. I take remedial teaching class today. Substitution duties on 8L and 8B. The last day of my teaching practice was a meaningful experience that helped me reflect on my growth as a student-teacher. It gave me confidence, practical teaching skills, and a better understanding of students and classroom management. This experience has motivated me to become a responsible and committed teacher in the future.

 November 27 I reached school on time, signed the attendance register, and went to the allotted room. There were no special events on this day, and the routine classes continued as usual. I conducted the diagnostic test on 9N, I had substitution duties on 9F and 8H. Participated in midday meal duty. We signed our records and evolution sheet.
