emember seeing this on an old ( very old) English TV show called Why Don’t You, when i was a kid and running off to my mum sewing kit to try to take her needles. I tried to explain it to her that if ever we were lost i was learning how to save us. Luckily she let me go.
Useful, simple, easy and fun. This Chromatography experiement is suitable for all ages. I have run it with 7 year old ESL students and it is a great way to spend a lesson. Free resources included!
