To make a model of a mountain, use a soda bottle or a tall cardboard cylinder as the center of the mountain. Attach cardboard strips from the high point to a wooden or cardboard base. Cover with paper-mache strips and paint.Know More
Cut a 2-foot square base out of heavy-duty cardboard. Alternatively, use a lightweight piece of wood for easier carrying. Paint your base using a solid color.
Find a 2-liter soda bottle, a thick cardboard tube or any other tall and narrow container. Using a heavy-duty glue, attach it to the center of your base. Allow the glue to dry completely.
Cut long cardboard strips about 2 inches wide. Use masking tape or glue to attach them to the top of the bottle. Angle the strips down to the base. For a steep mountain, use a sharp angle. For a bigger mountain, use longer strips and a more shallow angle. Tape or glue the bottom end of each strip to the base.
Mix a paste that is 1 part flour and 1 part water. Stir it well to get rid of any flour lumps.
Coat long strips of newspaper in the paper-mache paste. Lay them horizontally around your mountain frame, making sure to cover every hole. Add extra layers of paper to form cliffs and crags on the mountain surface. Allow the project to dry completely. If the mountain feels flimsy, add a second layer of strips.
Paint the dried surface of the mountain using brown paint. Simulate grass with green paint, or draw on rocks with gray paint. For a wintry look, paint a white snowcap on the top of the mountain.
One of the easiest ways to build a working model of the solar system is to suspend the sun and planets in their orbits from a circular piece of cardboard. Draw circles on the cardboard to represent the planets' orbits and hang each planet from the cardboard on a piece of fishing line.Full Answer >
Gelatin, fruit and candy can be used to make a 3-D model of an animal cell. The gelatin is used to form the cytoplasm or base of the cell. A light color should be used so that the candies and fruit used to portray the components are easily seen.Full Answer >
A model of a brain can be made using a Styrofoam ball with modeling clay that is molded to form the shapes that make up the brain. Different colors of modeling clay can be used to highlight the different parts of the brain and toothpicks with small pieces of paper can be used to label the different parts.Full Answer >
The Bohr model of the boron atom has a nucleus in the center and two energy levels, also known as shells, or orbitals, around the outside. Two electrons orbit the first energy levels and three orbit the second. Five protons and six neutrons occupy the nucleus.Full Answer >
