This baking soda and vinegar science experiment will allow the children to see how science is used every day. It is a tasty chemical reaction will increase the children’s understanding of this topic.
Bowl, cup, mixing spoons, round baking pan (greased)
1 cup milk
1 teaspoon vinegar
2 cups flour
½ teaspoon salt
½ teaspoon baking soda
Making Irish Soda Bread
1. In this experiment you are going to make Irish Soda Bread with the children.Before you start baking, show them the ingredients.
Question to ask:
- Why do you think there is baking soda and vinegar in this recipe?
- What effect will these two ingredients have on the bread?
2.Start baking process
- Preheat oven to 400 degrees.
- Mix milk and vinegar in cup and set aside for about 10 minutes. This will curdle the milk.
- In the bowl, stir together the flour, salt and baking soda.
- Stir the milk mixture into the flour mixture until smooth.
- Scrape the dough out of the bowl onto a floured surface.
- Form dough into disk shape and put into pan.
- Bake for approximately 15 minutes.
3. When the bread is baked and cooled slice a piece for each child.
Have the children observe the air pockets in the bread. Discuss that, just like in their previous experiments, the mixing of the baking soda and vinegar created bubbles.he bubbles in the bread just happened to become stuck in the dough.
Note: This is the final activity in a series of experiments on the chemical reaction of baking soda and vinegar. This series begins here: Baking Soda and Vinegar Science Unit
