Praise and Worship, what is the difference?

What does "praise" look like? How does it differ from "worship"? We are urged/called to/commanded to praise God (psalms 146:1 and others), but what is it and what does it look like? Romans 12:1-2 states: I appeal to you therefore, brothers,by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.(ESV)
