Another object lesson I did with the older kids was this one involving baking soda and vinegar. It is so easy to do. Just put some baking soda in the bottom of a cup. Make sure it is on something that will catch the spillover. We talked about our anger and how if we let it build up, it will eventually spill over or erupt and we’ll say and do mean things to those around us. It’s at this point that you want to pour some vinegar into the cup so that it can bubble up and spill over. Then you can ask the kids for ideas of things they can do to deal with their anger, so they don’t boil over, too.
