In this activity, students will work in groups of four to complete a thermometer investigation using the Scientific Method. Throughout this detailed inquiry, students will learn the components that make up a thermometer, along with the units of measurement (Fahrenheit and Celsius). In the first part of the activity, students will use the thermometer to measure three different temperatures of water (room temperature, warm, and cold). The goal of this portion of the activity is for students to see the thermal energy of the water expand or contract the mercury within the thermometer. The second part of the activity will lead students to determine whether food coloring travels faster through warm or cold water. The teacher will put one drop of food coloring in both the warm and cold cups, and students will observe which cup the food coloring disperses/dissolves the fastest. This section is included to explain how molecules move faster in warm water and slower in cold water.
This learning activity was created as a result of the Girls Engaged in Math and Science (GEMS) Resource Development Project, in partnership with Dothan City Schools.
