Hi Vann
ReplyDeleteIt's great to see your enthusiasm for science and I'm happy that you asked Axle when you weren't sure about a question.
In your blog introduction, it would be good if you told us one fact about the pH scale that you've learnt.
Keep working hard and making sure that you understand everything that you are learning in science.
