Objective: Children will use a thermometer to understand hot and cold temperatures.‹ Return to Theme
Thermometers measure temperature by using a liquid material, either mercury or ethyl alcohol, that is sensitive to changes in temperature. Most thermometers for domestic use contain ethyl alcohol that is colored with red dye. The part of the thermometer containing the red liquid is in a narrow tube with a bulb at the bottom. The red line on the thermometer changes when it is heated or cooled. When a thermometer is heated, the red liquid inside the narrow tube expands, causing the liquid to rise, or go up, in the tube. When the thermometer is cooled, the red liquid inside the tube contracts, causing the liquid to go down inside the tube.
Temperature is typically measured by degrees Fahrenheit or degrees Celsius. A Fahrenheit temperature is based on the temperature of water freezing being at 32 degrees. Temperatures measured in degrees Celsius are based on the water freezing mark being 0 degrees. We feel temperature through our sense of touch. Most people feel comfortable around 70 degrees Fahrenheit.
Take caution to make the water very warm, but not so hot as to scald fingers.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
