Understanding Temperature and Safety

In this science lesson, students learn about the properties of matter, focusing on temperature. The lesson covers how to describe and measure temperature using thermometers, both analog and digital. Students are taught to observe temperature through touch while being cautious of hot objects. A class activity involves using thermometers to measure the temperature of different liquids. The lesson concludes with safety tips for handling hot objects.
