How long do the activities in the Usborne Fact Force lessons for schools take?

The schools' resource packs to accompany Usborne Fact Force school events are aimed to be completely open-ended. 

There are quick activities you can print out and share with a whole class, or even year group, which might only take 10 minutes – or there are research projects that might take pupils working in small groups a whole lesson. 

You can do one activity, or you can work through the whole pack. You could theme a whole day, or even a whole week, around an Usborne Fact Force event.
