The new sample lesson plans, some of which are accompanied by animated videos, are part of a broader, K-12 health and sex education curriculum adopted by the New Jersey Board of Education. The plans, which were first reported by Fox News, are now being reviewed by individual school districts in the state.

In one proposed lesson plan aimed at fifth graders entitled 'It's All about the Hormones,' students are instructed to watch a video containing animation called  'Puberty and Transgender Youth.'

'Whether you identify as male, female, gender queer or something else, you're perfectly normal, and there are lots of ways to manage puberty so that it can be a fun, exciting time rather than a scary or stressful one,' the video states.

'If you feel you want more time to explore how you feel about your gender before your body starts to change, it's important to talk with a parent, counselor, therapist or doctor about the feelings you have regarding your gender,' the video details.
