engage students in learning a concept or skill using a digital tool/resource.

Phase:
Before/Engage, During/Explore/Explain
Activity:
The students will watch the YouTube video to introduce the concept of balancing chemical equations. After watching the video, the students will be given an activity sheet with unbalanced chemical equations (Balancing Chemical Equations Activity Sheet). The students will use neon Expo markers to model the molecules in the chemical equation. They will work together in pairs and will have at least four different colors of Expo markers. For each equation, the students will assign the atoms or polyatomic ions a color and draw a circle for each atom. They will then draw circles to balance the chemical equation.
Assessment Strategies:
The teacher will walk around the room to ask the students questions and then will be able to assess the students formatively or summatively after the students complete the sheet of equations.
Advanced Preparation:
The teacher will need to make copies of the sheet of equations and obtain four different colored neon Expo markers for each student pair.
Variation Tips (optional):
If neon Expo markers are not available or they will not work on the desk or table tops, the teacher can use regular markers and butcher paper. Chalk markers also work well with the desk and table tops. If the teacher would like, bingo chips, pop beads or any other items that the teacher may have in at least four different colors may be used for this activity. The teacher can use this method of balancing chemical equations with any sheet of reactions.
