Compete with thousands of other students from around the world by taking part in this epic crystal-growing experiment aimed at students aged 7-16, hosted by the Royal Society of Chemistry (RSC).
The aim of the Global Experiemnt is to find the exact conditions that allow you to grow the biggest, most impressive crystals of alum, epsom salts, potassium nitrate, table salt and sucrose. Students do the entire process themselves, then post their pictures and data onto the RSC’s global, interactive results map. Here’s their instructional video:
Through getting your students involved in this year’s Global Experiment, you’ll be teaching them about dissolving, saturation and crystal growth. You’ll be engaging them in a fun, interactive science project they can easily continue at home. The RSC has even provided instruction packs, lesson plans and an instructional video to make the planning process as easy as possible for teachers.
It’s free to take part, and no specialist equipment is required. It can be done entirely using a few cheap things purchased from a local store. It can be done at home, at school or at an after-school science club.
The RSC’s Global Experiment has been a great success in recent years. It follows the 2013 Global Experiment: measuring the quantity of vitamin C in fruits and vegetables, and the 2012 Global Experiment: Chemistry in the Olympics.
