Can 8-Year-Olds understand concepts of Einsteinian physics?

This paper reports the first study on the ability of Year 3 students (ages 7 to 8) to conceptualize Einsteinian concepts. This paper reports that children aged 7-8 are not too young to learn key Einsteinian concepts, and the benefits of reinforcement indicate that longer programs are needed for ideas to be consolidated.
