Percentage Yield is interactive Lesson Power Point is the best resource to deliver the concept of “Actual and Percentage Yield” in a most fun and engaging way. The ppt is adequately animated to give teacher full control of the discussion making it highly interactive. Contents- Understanding the cocept of Yield Fun activity Real life example of Yields Actual Yield Theoritical Yield Calculating Theoritical Yield step-wise Interactive questions and HW assignement Performance Task word file.

Performance task - Hess Law This is an engaging practice task focused on Hess’s Law. Master the art of determining enthalpy changes for chemical reactions using indirect methods. Through a series of carefully designed exercises, you’ll piece together reaction pathways and harness the power of stoichiometry to predict overall energy changes. Perfect for both beginners and those looking to refresh their knowledge,or exam practice or just a quick Formative assessment.

The power point is a highly appreciated school assembly which I prepared that has following contents- Moral Value- Courage -Festivals of International Importance (Global World) -Thought of the week -Innovation -Fun facts -Water Conservation Campaign

This is yet another ppt containing ard 30 slides on various important topics . This can also be used for various enrichment lessons. Topics include - Respect -Famous quotes -Food for thought -Inspirational video on respect -Innovative articles in daily life -Global warming and steps we can take at student level to reduce carbon footprint

The powerpoint is yet another highly appreciated assembly ppt on following contents -Thought of the week - Moral value (Empathy) -Short story (inspirational) on empathy - Festivals and their importance - Interesting facts about human body.
