Welcome to the lesson-writing section of PEN! This is where you can contribute to our curriculum by writing lessons that will be used by people all over the world.

You might be recording a lesson you've already taught many times, or you might be starting completely from scratch. In either case, we suggest you take a look at:

• lessons we're currently developing - get an idea of what sort of lessons we already have
• background units that exist. These are short explanations of concepts or experiments that could be useful for you.
• our lesson philosophy - see what we're trying to focus on in PEN lessons
• Have a look at some PEN teaching tips to get advice and ideas for activities and structuring lessons.

Our main focus right now is the Solar Photovoltaic Curriculum. You can contribute to this by:

• doing research and/or sharing knowledge or activity ideas for lessons currently in stage 0.
• creating a lesson outline (stage 1) for any stage 0 lesson that has lots of information (think about how long the lesson might be - you might want to split it into two or even more lessons at this point)
• testing activities or experiments listed in stage 1 lessons to make sure they work as expected - share your results!
• write the next stage for any lesson that is at stage 1 or higher and has feedback. Refer to the explanation of stages to see what each stage should focus on.
