There are so many you could do! It always depends on whether you are looking for theme specific or just general (to keep them busy). Open-ended art activities are by far the best. Giving them materials they can use alone, such as, scissors, glue, tape, paint, markers,etc to create their own project gives them a sense of pride and also is how they learn! Keeping (free) materials for them to explore with is also important. Items straight from your recycle box! Egg cartons, paper tubes, cd's, water bottles, bottle caps, newspaper, boxes, etc. You would be amazed at what they can come up with on there own.
