This week's podcast was made to describe how we made chalk. The instructions are in NZ School Journal Pt 02 No. 4 2000. You just need some plaster of paris, some water, a plastic bag and some food colouring. If you want to try it at home we can lend you the school journal. Leave your request in the comments. School Journals are a wonderful resource.
This blog is to share some of our learning. We would love your feedback by making comments. To leave a comment all you have to do is click on Comments at the bottom of each blog post.
