Dear [insert name],
I came across BrainChild Academy recently and was impressed by their hands-on science and technology program for schools. They use a combination of lego-like electronics (littleBits) and craft in a way that clearly engages the students. The program is linked to the curriculum and they have taught at schools such as Newtown Public School and St Ignatius' College.
I am writing to see if this is something we could introduce at our school.
Julian from BrainChild is happy to come to the next P&C meeting to give a 10min presentation about the program. The cost is $1800 for a 10week term for up to 32 students, however the format and pricing can be flexible. BrainChild brings the electronics and has public liability and WWC covered.
