Provide a variety of snacks for the children to choose from to create a bag of food for a space trip. Suggestions: raisins, dry cereal, pretzels, goldfish, peanuts(if you have no one allergic), M&M's, etc. Give each child a snack size zipper baggie to put the snacks in. They will have to choose wisely to get the snacks they want into the small baggie. Save the baggies for a pretend space trip at afternoon snack time!
