Support DONAT STEM

DONAT STEM is made by one science teacher in Rwanda, BIZIYAREMYE Donat, for learners and teachers who have a phone but no laboratory. Quizzes, simulations, virtual labs and lesson plans stay free. Your support pays for new labs, free Lab Packs for rural schools, and the costs of hosting and the AI helpers.

🏫 Sponsor a school

Choose a rural school (or let us choose one) and pay for its Lab Packs, teacher papers or worksheets. The school receives the resources free, and you receive a thank-you with what was given.

Write on WhatsApp +250 788 804 242 to agree the school and the resources.

🤝 For organisations: sponsor a lab

Educational organisations, foundations and companies can support a lab, a themed collection (Renewable Energy, Water and Climate, Agricultural Science), a new engineering challenge, or free Lab Packs for rural schools.
