WEEK 10: SEPERATION OF MIXTURES
PAPER CHROMATOGRAPHY
The EcoSTEM programme seeks to enhance practical STEM and environmental sustainability education across the EduSpots network communities and beyond.
All our programmes are created by our local team, using resources that can be found in rural communities low-cost or recycled, with ideas relating to local Ghanaian environments and lives, also linking to the national curriculum.
Each month, we launch a monthly challenge with our network of EcoSTEM clubs which engages students in JHS to work as a team to conduct some form of scientific experiment or activity.
Check the sections below to see some of our amazing EcoSTEM challenges!

Student attendance at community EcoSTEM clubs can be erratic so ongoing project work is difficult and as a volunteer (or teacher), you need to think of a new activity for each session, which can be really draining. But that is exactly what it means to belong to a network of daring volunteers: To get out of your comfort zone and make things happen!
The EduSTEM Club guide seeks to alleviate some of the difficulties associated with maintaining a STEM Club. Here’s what we suggest:
