Lesson Details


Levels Taught:
High School
Having taught high school science for the past 20 years, I have vast experience with teaching all levels of learners. I have taught Chemistry at all levels - from the beginning, introductory course up to AP Chemistry. When teaching, I like to employ the 5 E model, which include the following components: engaging the student, exploring the concept, explaining the material with vivid examples, and then if time allows, extending one's knowledge with more challenging problems. Finally, I would do a quick evaluation to ensure that the student has gained a true comprehension of the material learned.

Hello, Chemistry students!

I am a currently Nationally Board Certified teacher who has taught high school Chemistry and Physics for 20 years. I have vast experience teaching students of all levels, from the beginner to advanced. Being a teacher, I truly enjoy explaining concepts and making them easy to understand for the student. As an extension of my passion for science, I also enjoy creating online videos of Chemistry concepts.
