Say to the children “We are going to create a chemical reaction.” Show the children the baking soda. Have each child touch and discuss how it feels. Show the children the vinegar and let them smell it. Encourage more vocabulary. Have the children spread the baking soda on a tray, covering the entire area. Pour vinegar into small cups and have the children add two to three drops of food coloring to the vinegar. Have the children use droppers to draw the vinegar from the cup and drop onto the baking soda. Discuss with the children what they see happening. Add a few squirts of child-safe liquid soap and see what happens next. Encourage the children to come up with more words about the reaction, such as “it fizzles.” Take pictures and dictation to document the experience. This activity could be done in small group.
