Chapter 12 The Invertebrates

Welcome to the first weeks of school we are starting the 7th grade with our annual insect collection. There is a section entitled 7th Insects that contains almost everything you need to know about your insect project.

This section of the web site has been created to help you with the academics of Chapter 12. For now we will be concentrating on sections 12A and 12F only. I am posting links to videos and web sites that will help you understand what is being taught in these sections.
