Enlarge a picture of a lighthouse for your class. Divide the picture into rectangles using a black marker. Assign one rectangle of the picture to each student in your class. Instruct each student to recreate his section using whatever tools he has at his disposal. These may include markers, crayons or colored pencils. When your students finish, attach the pictures to a large wall in your classroom using double-sided tape. Place the pieces in the correct positions to form completed lighthouses. Allow your students to decorate the wall around their pictures.
Place a large table in your room, lay a large sheet of paper over it and set up a large lighthouse on one side. Instruct your students to go outside and collect small rocks. When they return, show them how to place the rocks around the base of your lighthouse and the area around it. Instruct them to stack some of the rocks on top of each other to create a rocky beach effect. Give your students sheets of blue crepe paper and instruct them to cut them into small squares. Teach them how to wrap the paper around their fingertips, dab them into glue and then stick them on the table, forming a water scene beside the rocky coast.
Give your students some clay to work with. You can use the no bake, air-dry clay, but make sure that your students cover their desks in paper to protect their work spaces. Teach them how to work with the clay to build their own lighthouses. Show them how to carve details into the clay, such as windows and doors. Use a hair dryer to help the clay set up, and then let the lighthouses sit overnight. Instruct your students to paint their lighthouses after they are completely dry.
Give each of your students a Styrofoam cone. Show them how to cut the tips off of the cones, creating a lighthouse-shaped form. Instruct your students to decorate their cones by drawing designs on the sides to represent the doors, windows and paint. Give each student a small light to place in the top of his lighthouse to finish the project.
