I know we call it STEM education now, or STEAM if the Art department get sniffy about it, but really in the opinion of this long in the tooth teacher most of these activities have been around for years. I teach in English in a Primary school in Hong Kong, and i have used these lessons to both spice up my lessons and to show the value and real world applications of my subject. When students can see a purpose for the subject they are learning their engagement and motivation will skyrocket. (not unlike the balloon rocket experiment on my site!)
It almost pains me to write that title. I make apps to help students, I have about 12 of them on both Google and Apple and they are pretty good. None of them are the one I am talking about here though. Here is is all about Teach Your Monster to Read made, and made really well, by Usborne in the U.K. The links are all at the bottom for the app and website.
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!
