I hope nobody minds me posting when I am not involved in home education. I am a teacher and was looking at the Silverstone museum for a school trip and came across their home education days.
https://www.silverstonemuseum.co.uk/learn/education-groups/
It is £10 per child with one free adult per child and there are STEM workshops (exactly the same as they do for the school visits) and then access to the museum.
Next one is 12th September, so I thought I would share it here in case it is of interest to anyone.
