Hello, I'm Ruth Tsui, creator of STEM Explorers.

I've worked in schools since 2009, across the pre-school and primary age phase, with children aged 2 to 11 years old, both as a classroom teacher and as a STEM enrichment provider, running clubs and workshops in schools and the local community.

Using over 10 years of experience I share tried and tested practical STEM enrichment activities that develop conceptual understanding and key life skills in your children.

Perfect for home educating families, primary school teachers, early years practitioners and those with a dream to run their own STEM clubs in their local community.

All the planning, videos, background information and explanations are ready to go, at their level so there's no need to be an expert and it saves you time trawling the internet trying to find the perfect activities to engage and excite your children.

Why did you create STEM Explorers?

I love STEM, making it fun, bringing it to life...my aim is to empower you to do it yourself, to run your own STEM Clubs with ease and confidence.  Being a STEM Explorers member means you:

don’t need to be an expert

don’t need lots of time

don’t need lots of specialist kit

don’t need to worry it won’t work

STEM is for everyone, it doesn’t need to be complicated, it’s not a big secret.
