The Chemguy App has arrived! I'm Rob Lederer and I taught chemistry for 35 years. I've taught all high school levels of chemistry, including AP Chemistry and IB Chemistry, too! Since 2003, I have been known as Chemguy to the students outside of my classroom. My Chemguy YouTube videos have millions of views. The Chemguy App that I have personally built has distilled my teaching career into a course that completely covers high school chemistry, AP and IB material, and first year university chemistry. Everything is covered: The Periodic Table, Compounds and Reactions, Stoichiometry, Solutions, Gases, Atomic Theory, Chemical Bonding, Molecular Shapes, Energy, Electrochemistry, Chemical Equilibrium, Acids and Bases, Organic Chemistry, Chemical Kinetics, Thermodynamics, and Calculating Uncertainty Values. Phew! This is what you get in the Chemguy App: 1. Over 200 video lessons, where I teach all the chemistry principles, give detailed explanations, and problem-solve through all the calculations in every unit of study. 2. My entire classroom note package. All the material explained, with tables and diagrams and pictures. At the end of each lesson there are practice problems, over 1000 in all, to hone your chemistry skills. 3. Tests! I have made close to 100 interactive quizzes for all the lessons and summary unit exams, too! That's a total of over 1000 questions to practice! 4. Chemguy Messaging. After going through all of the above, is there still something that you need help with? Send me a text in the chat function of the app! Let's talk about it! So, watch the videos, read the notes, do the practice problems, have fun with the quizzes, and cap each unit off with the exam. And if something is bugging you, chemistry-wise, send me a message and let's chat about it! If you want to know more about me, what I've done and what I continue to do, please visit my website, roblederer.ca
