Snacks are always a winner when it comes to kids, so why not use snack time as an opportunity to make something neat and to learn about the solar system. Any round snacks will work for this project. You can use round fruit, cookies/cupcakes, or even a round cookie cutter to cut sandwiches or whatever other snacks into planet shapes. Arrange the shapes of snacks according to their rightful place in the solar system. You may even want to use frosting or food coloring to add details. This is one instance when it is not only ok to play with your food, but it is actually encouraged. If it is still safe, feel free to eat this craft when you are through.
