YSA Juniors is an exciting way for children in Key Stages 2 and 3 to help develop their excitement, engagement and interest in the wonderful world of STEMM!

Did you know?
STEMM stands for Science, Technology, Engineering, Maths and Medicine

“Do you think like a scientist? Because if you like to ask questions, listen to others, notice changes or simply let your mind wonder… then you already are! Science isn’t just a classroom subject, it’s a way of exploring and understanding the world you live in and YSA Juniors is your perfect companion on this adventure!

Think of YSA Juniors like a curiosity diary. Go out and discover something new, ask lots of questions, have a go yourself and share your findings with a friend! Soon you’ll have an activity sheet full of stickers to celebrate everything you’ve learnt and a brain bursting with ideas! Have fun and who knows what you’ll discover next!”

What is YSA Juniors?

YSA Juniors is an exciting activity designed to help schools and families shape the STEMM experience that their children receive. We think the sooner the next generation of STEMM professionals get started the better. That’s why we have developed the YSA Juniors scheme, and targeted it at students aged 7 to 13. Spending time encouraging younger children to explore the amazing world of STEMM will develop their curiosity and ignite their passion, turning them into a YSA Junior!

How does YSA Juniors work?

Helping your YSA Junior to complete their journey couldn’t be easier. You decide whether what they do deserves a sticker, so you are in control of how hard they have to work, and what counts. We’ve given you some examples below, but you can also follow us on Twitter (@YouthSTEMM) where we will be sharing lots more ideas.

You can do one experiment or activity across a whole STEMM area, or you can mix and match. The only essential element is fun! We want YSA Juniors to help us all re-engage with the engineers, scientists, mathematicians, techies and medics hiding inside.

Each YSA Junior pack is £5.00 (P&P not included), and includes an A4 booklet to record their findings, a sticker card and sheet and a certificate and badge to award on completion of their journey.

When they have completed their achievement card you can award them their badge and certificate. Make an occasion of it! Present it at school, at home, at a party, in the park. Shout about it, tell their friends and family, make sure they are proud of their achievement and that they celebrate it.

And if they really love it… buy another pack and go again!

We hope you have a great time exploring the world of STEMM with your YSA Junior – there’s a marvellous journey ahead.
