The tamariki had a marvellous time today discovering and exploring a new type of paint that comprised of baking soda, water and food colouring. There was more to this painting experience however, as upon the completion of their paintings, the tamariki would use pipettes to drop small amounts of vinegar on top of their painting, watching as the vinegar interacted with the baking soda, creating a bubbly foam.
The tamariki enjoyed an informative session with teacher Wendy at the worm farm. They learnt about slow moving worms in the winter and even had the opportunity to gently hold a worm in the palm of their hand.
The tamariki were actively engaging in using their senses throughout this activity, watching the foam expand and listening to the fizzing sounds as the baking soda and vinegar combined. This is a great way to introduce the tamariki to scientific concepts and an understanding on chemical reactions. The tamariki also engaged in problem-solving as they realised that there needed to be a large amount of baking soda in order for a stronger reaction. Exploration/Mana Aotūroa- Children learn strategies for active exploration, thinking and reasoning.
The tamariki were fascinated with the tickly sensation of the worm moving in their palms. They were also keen to examine the fruit and vegetable food scraps that feed the worms, identifying those that they recognised from their own diet. Te Wheke- Taha Tinana- This dimension represents the relationship of the child to their physical world. It concerns taking responsibility for ourselves, the respect and reverence of living things and the natural cycles of the physical world.
Maybe we could try making this concoction again tomorrow and adjust the levels of baking soda?
Thank you worms for providing such nutrient rich worm tea for our kindy vege garden!
