At Little Scientists, we are all about spotting STEM opportunities in the everyday. Exploring with sparkling water, or to children more commonly known as fizzy water, might not be an everyday occurrence but is a fascinating way to introduce gases (in this case carbon dioxide) and if you have access to a soda stream, it could be even more fun!
It is not necessary for you to have any understanding of chemical reactions for this activity. The beauty of this activity is that you can discover what substances are acidic or alkali within your house alongside the children. The colour changes, reactions and fizzes are a very exciting part of this exploration.
A chance to experiment with smells, textures and, although not in this activity unless heavily supervised, tastes is part of our experiences of the world. Using our senses is important to developing our sense of the world. This activity is a wonderful way to use STEM to develop observational skills.
You can see good results dyeing eggs with food colouring but to be honest, we used up all the food colouring in our house tie-dyeing t-shirts recently, so this year we had to improvise and try natural dyes instead. Luckily, our garden and the pantry provided some great options! But of course, it was not all smooth sailing so find out what we did!
