# Science Investigation

   17 March 2015   [Julia Hall](https://www.ststephenskearsley.co.uk/blog/author/Julia)   [Year 4 Blog](https://www.ststephenskearsley.co.uk/blog/category/year-4-blog)

Today we have been investigating reactions. We started with four white powders and we predicted how we thought each substance would react when we added vinegar.

We added the vinegar to each container and discussed each acidic reaction and recorded the results on a table that we had prepared earlier.

The results showed that bicarbonate of soda was the most reactive substance followed by baking powder, cornflour and flour.
