There is a lot of competition in a science fair, making it difficult to win or even place in the fair. One way to help ensure science fair success is to include visual models that demonstrate the theory of your experiment. For example, if your experiment uses a small car model to support the hypothesis, you can make a small model car from wood to use in your science fair display.
Apply glue to one side of a 1-inch wooden cube.
Press the glued side of the cube onto a wooden rectangle measuring 1-inch high by 4-inches long. Arrange the cube near one end of the rectangle. Allow the glue to dry.
Bend four small paper clips into circles with needle-nosed pliers.
Staple a paper clip circle to the underside of each corner on the wood rectangle using a staple gun. Angle the circles so that the holes face each other. This will create a set of holes on either end of the rectangle.
Cut a 3-inch long piece of 1/8-inch thick wooden dowel in half.
Insert a 1 1/2-inch long piece of wooden dowel through each set of holes.
Place a wooden wheel onto the end of each dowel, and place a dollop of modelling clay onto the end to secure it.
Paint the car with acrylic paint to customise it. Allow the car to dry completely before using it in your project.
