Best Science Tools: Digital Clocks & Stopwatches for Classroom Experiments, Lab Research & STEM Learning Activities

Science experiments are one of the many situations in which timing can be crucial. This guide teaches students how to use clocks and stop watches. Explanations are provided of how these tools can be used to study things, such as a person’s heart rate and how fast animals learn. Discussion about how to construct an experiment make it easy for readers to do one themselves—and one is provided for them to try. Real-world examples and labeled photographs make the text even more engaging.
