Mother’s day is May 8th but we are going to get a head start on some gifts. 

Bath bombs are a fizzy mix of dry chemicals that cause a chemical reaction in water and can be a soothing addition to a relaxing bath. We are going to explore energy in reactions with these bath bombs and make our own that we can gift to our mothers or anyone else we would like. 

The active ingredients in bath bombs are: 

sodium bicarbonate and citric acid react with water. 

Plan an investigation into the reaction of sodium bicarbonate and citric acid. 

based on what you learned from your experiments and using the ingredients available — make your own bath bombs!
