From the website: "Bring your family and enjoy 5 glorious days of free admission from July 21 through July 25, loads of special programming and fun for the whole family. Throughout the Best Days, The Bakken will show off its best programs (science theater, creative take-aways, innovative workshops, and more), while also partnering with community businesses and organizations for activities and treats."

Each day has a different theme, and with each theme, all kinds of different activities!
