Make a CLOUD! Fun science activity for kids. For younger children, this will have to be a demo (aerosol hairspray or blown out lit match is needed in a glass jar), but the children can still observe and record their Scientific method steps and can 'touch cloud' afterwards! :)
This "I'm done..." board is a great way to remind students of their choices once they have completed the current activity. By having this posted as a bulletin board or poster within the room, students would have a visual reminder of the acceptable options they have while awaiting transition to the next activity. This procedure would help maintain order as well as keep faster students busy.
