Family friendly attractions?

Hey people, I’m visiting grandparents in Springfield for a few days during spring break next week.

I saw the other post about some stuff to do, but do you have any other suggestions for family-friendly attractions? I got a 12yo sister and a 8yo brother in tow. All I am seeing so far is lots of Abraham Lincoln related museums and I’m not sure that will hold their attention for multiple days 😅

Thanks!
