Short Activities
Short activities are brief hands-on experiences lasting less than 15 minutes for small groups of people.
They are often presented at a table, cart, or demonstration space in a variety of settings such as a museum exhibit gallery, classroom, or other public or group setting. Multiple short activities can be combined to form a longer activity.
