This easy science experiment for kids is the first in our series on the chemical reaction between baking soda and vinegar.
This science experiment will introduce your children to the chemical reaction between baking soda and vinegar. They may not be able to completely understand what a chemical reaction is, but they will come to learn that this experiment will produce the same outcome each and every time it is performed.
Materials: One small cup per child, spoons, droppers, baking soda, vinegar
1. At a table, give each child a small cup containing baking soda. Have the children use their dropper or spoon to pour vinegar into the cup.
2. Observe what happens.
Questions to ask:
- What happened when you mixed the baking soda and vinegar?
- Did everyone create the same amount of bubbles?
- How do you think you can make more bubbles?
3. Rinse out the cups and allow the children to try the experiment again, this time testing their ideas on how they can create more bubbles.
- Were you able to create more bubbles?
- What did you do to create more bubbles?
- Did you make a mess?
4. Close this activity by asking the children what they think will happen if they mixed baking soda and vinegar again.Do they think they will always get the same result, will there always be bubbles.
The children will come to understand that this is a predictable outcome. Every time they mix baking soda and vinegar they will get the same result.
You can expand upon this lesson by repeating the experiment with baking soda and water. First, question the children about what they think the outcome will be. Allow them to test their hypotheses and discuss the difference in the outcomes.
Another easy science experiment for older children would be to use old water bottles and attach a balloon to the top of the bottle after adding the baking soda and vinegar.
