In this STEM activity, students were challenged to design a thermometer that shows changes in temperature. The goal was to make the liquid inside move when placed in hot or cold water. Students looked at real thermometers to see how they are built and thought about how science, engineering, and math are used in the design. They brainstormed and sketched different ideas, then used materials like clear straws, water, food coloring, rubbing alcohol, tape, clay, rulers, and spoons to build their thermometers. By testing and observing their models, students learned how liquids can expand or contract with temperature changes and saw STEM principles in action.
