[ Primary & Secondary Education ] Open Question : how can i make these history standards easier so a kid about 10 years old would understand?

1. understand the history of the constitution after 1787 with emphasis on federal versus state authority and growing democratic. 2. examine the effects of the civil war and reconstruction and the industrial revolution including demographic shifts and the emergence in the late 19th century of the united states as a world power? *THANK YOU SO MUCH!*
