You are a pioneer who needs a device to suspend a cooking pot over a fire at different heights. Your task is to build a model of a wooden support structure with an arm that: - is stable - will extend far enough over the ‘fire’ to safely cook food without burning the support structure. - is adjustable so that food can be moved closer to the fire or further away from fire as needed - is made only out of the materials provided. When you have finished building your model you will be presenting it to your class.
