Material for new VEX IQ Club

Hi,
We just started a new VEX IQ club.
What is the most recommended club activity project recommendation to follow?
I saw below contents but it looks not bad but any other recommendation (sites, books, activity ideas, etc)

note
We are not 100% sure compete for competition but more focused on STEM education.
