How long do Usborne Fact Force lesson activities typically take in schools?

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.
