In this lesson, we will continue to explore inputs, processes and outputs by integrating an electrical system with a mechanical system. We will build a mechanical system and integrate an electrical system and evaluate this product. We will also explore some other inputs and outputs and explore which ones we could use. Such as, different switch types as inputs and bulbs, buzzers, etc., as outputs. This lesson includes some physical activity and equipment beyond pen, paper or pencil. Please make sure your child is adequately supervised.
