My aim is to help students not just score well, but also think & relate concepts to realworld science, and develop strong problemsolving skills.

During their recent ecology lesson, Palak and Hussain explored the critical role of keystone species, illustrating their impact on ecosystems with examples such as purple sea stars and tigers. The discussion then shifted to energy sources, delving into the processes of photosynthesis, overall productivity, and the key differences between Gross Primary Productivity (GPP) and Net Primary Productivity (NPP). Hussain was tasked with reviewing questions from the chapter, preparing for their next class which will commence with 'Modeling the Ecosystems'.

Palak Jain guided Shimaa Aref through a comprehensive science lesson, covering significant figures, unit conversions, graphing, error analysis, atomic structure, and periodic table trends. Shimaa actively engaged by practicing calculations, unit conversions, and identifying various trends. Their next lesson will delve deeper into atomic structure and other topics from Shimaa's revision sheets.

Palak and Hannah delved into the fascinating field of human evolution, specifically examining DNA evidence. Their discussion covered both mitochondrial and nuclear DNA, crucial for tracing migration patterns and understanding our ancestral journey. Key topics included the 'Out of Africa' hypothesis, haplogroups, and the vital role of fossil records. Hannah was tasked with reviewing the material, and they arranged a follow-up lesson to continue their exploration.

Palak and Hannah recently delved into genetics, reviewing key concepts such as causes of variation, mutations, and chromosomal mutations, all in preparation for Hannah's upcoming test. Their comprehensive discussion covered fundamental topics like meiosis, mitosis, genes, alleles, and phenotypes. For their next lesson on Monday, Hannah is tasked with reviewing specific PPTs and preparing practice questions.

Palak reviewed phylogenetic trees and cladograms with a student from Aurora, discussing the differences between them and how they represent evolutionary relationships. The lesson also covered homologous and analogous structures, vestigial organs, and immunological and DNA sequence evidence for evolution. The next lesson is scheduled for Sunday night to continue preparing for an upcoming test.

Palak and a student from the University of California San Diego discussed ecological niches, resource partitioning, and the competitive exclusion principle. Their lesson also covered different types of relationships between living organisms, such as parasitism, predation, and mutualism, and how diseases affect ecosystems. The student was assigned homework to review the material covered in class.
