Create model roller coasters with glue, cardboard, construction paper, scissors, ribbons and crayons. Glue green construction paper onto cardboard to resemble grass. Make the structural supports of the roller coaster by gluing crayons together and gluing them to the ground (the cardboard). Wrap the ribbon around the crayon bases to make the roller coaster's curves, twists and plunges.
Make character ears to wear at an amusement park. Cut stiff colored felt in the shapes of animal ears. For instance, cut stiff black round ears for mouse ears. Use stiff white felt for bunny ears and stiff brown felt for dog ears. Attach the ears to a headband with a hot glue gun. Tie a ribbon into a bow and attach it to the headband between the ears, if desired.
Build an edible haunted house, a classic feature of many amusement parks. Use graham crackers for the walls of the house. Attach the crackers and support the house with thick frosting or cake paste. Create cobwebs with white cotton candy. Use candy corn to add peaks to the roof. Surround the house with grass made out of coconut shreds died with green food coloring. Add jelly beans, licorice and other treats, as desired.
