Chemical Reactions Lesson Plan

Learning Objective

By the end of this lesson, students will be able to:

  • Define chemical reactions and identify different types of chemical reactions.
  • Create an animated gif using Brush Ninja to demonstrate a chemical reaction.


  • Computer with internet access for each student or group of students.
  • Brush Ninja website.
  • Whiteboard and markers.
  • Chart paper and markers.
  • Relevant videos on chemical reactions (optional).


  • Begin by asking students if they know what a chemical reaction is. Write their responses on the whiteboard.
  • Use relevant videos or visual aids to explain what a chemical reaction is, the different types of chemical reactions, and examples of everyday activities that involve chemical reactions.
  • Introduce Brush Ninja as a tool for creating simple animations.
  • Show students how to use the basic features such as drawing tools, stickers, timeline, frames etc.
  • Divide the class into groups of 4 or 5 students each.
  • Ask each group to brainstorm ideas for creating an animated gif that demonstrates a particular type of chemical reaction like combustion, acid-base neutralization etc.
  • Provide chart papers for planning out their animation sequence including sketches or storyboard designs.
  • Using their chart papers as guides, have each group create an animated gif that demonstrates a specific type of chemical reaction using Brush Ninja.


Students will be assessed based on:

  • The quality of their animations.
  • Their ability to identify different types of chemical reactions in their animations.
  • Their ability to articulate the concept behind the animation.


This lesson can be extended by having students research more about a specific type of chemical reaction or an element involved in a particular type of reaction.
