1. Grade 6
The lesson plans use the terms ‘male’ and ‘female’ when referring to biological sex (sex assigned at birth), such as when discussing reproductive anatomy. A person’s reproductive system can be male, female or intersex (not clearly defined as either male or female).
People are assigned a sex at birth based on their reproductive anatomy. Sex assigned at birth is independent of gender identity. Gender identity is a person’s internal sense of identity as female, male, both or neither, regardless of their biological sex assigned at birth.

2. Reproductive Systems
This is a good introductory slide so that students can understand the relationship of the reproductive organs to the rest of the body. Show this slide and discuss the difference between internal and external. Then introduce the difference between frontal views and side views of the body. The female reproductive organs are shown primarily using the frontal view, while the male reproductive organs are shown primarily using the side view.
