As we read the story of Hansel and Gretel the children began to ask questions about the Witches potions; which ingredients does she put in her potions? what can her potions do?
We planned a science investigation using bicarbonate of soda and set out to answer the question;
Can I make the powder fizz?
We explored bubble bath, lemonade, vinegar, shaving foam and lemon juice before predicting which ingredient would cause a reaction when mixed with the bicarbonate of soda. It was very exciting as we mixed the ingredients together and watched to see what would happen. As we explored we found that the vinegar and lemon juice made the powder fizz and therefore caused a reaction.
