Leeanne,
Curious Mind has offered whole school CPD for a number of years, has your school availed of it?
You can sign up for 3 by 2 hour sessions, with a face to face facilitator (if one is available in your area) or online.
Schools have reported these to have a significant impact on teacher confidence and children’s Science learning.
