Bath Bombs Activity

Science

STE(A)M

This activity primarily focuses on chemical reactions, as it explores acid/base and decomposition reactions through creating a take-home bath bomb!

Concepts at a Glance

By the end of the activity, students will be able to:

Describe how an acid (citric acid) and a base (baking soda) react in water to produce a gas (CO₂).
Identify evidence of a chemical reaction (fizzing, bubbling, gas formation, new substances).
Explain the role of different ingredients in a bath bomb (citric acid, baking soda, Epsom salts, cornstarch, oil, water, colour, fragrance).
Predict how changing the ratios of ingredients or conditions (amount of water, temperature) might affect the reaction.
