Today in J4K we had some fun experimenting with mini volcanoes. This activity is always popular when we do it outside on a larger scale. However today I wanted to give our tamariki the opportunity to experiment on a smaller scale and see if we could get the same results.
We used trays with small compartments and droppers for our dye and vinegar. Everyone had a turn making a small mound of baking soda then adding some drops of dye before going ahead and adding vinegar to watch the eruption.
We discussed how adding vinegar to the baking soda caused a chemical reaction, hence the fizzing. We then experimented with varying amounts of the ingredients to look for any differences in the reactions.
Experimenting and trying things out gives the children opportunities to extend their knowledge and curiosity; which are important and valued ways of learning.
