This engaging chemical reaction powerpoint gives students an overview of the definition, characteristics, types, and examples of chemical reactions. The unique feature of this powerpoint is that it correlates with a virtual lab (which is free online) that allows students to see the reactants and the products. They can clearly visualize and identify the signs of a chemical reaction using the demonstrations provided. This 25 slide show presentation really got my students to understand the meaning of chemical reactions and I hope it works for you. If you like this lesson, please check out the chemical reaction demonstrations and test and other physical and life science lessons at my store. Thank you!
