About time : a first look at time and clocks

Teaching clocks, calendars, and how to tell time can be such a fun subject to teach, especially with the following picture books on the subject. Kids are so proud of themselves when they can 'finally' tell time, even if it's just to the hour or half hour. All teachers and parents LOVE seeing that excitement in children! Also, if you are teaching time and some of your students are struggling, try using one or more of the picture books listed below during your reading time. Sometimes it just needs a different angle to help it sink in. This cross-curricular approach is a great way of 'covertly' teaching about what time is, how to tell time, and calendars.

About Time: A First Look at Time and Clocks

An atomic clock is a clock whose timekeeping mechanism is based on the interaction of electromagnetic radiation with the excited states of certain atoms. Specifically, either a hyperfine transition in the microwave , or electron transition in the optical or ultraviolet region of the emission spectrum of an atom is used as a frequency standard for the timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services , to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS. The principle of operation of an atomic clock is based on atomic physics ; it measures the electromagnetic signal that electrons in atoms emit when they change energy levels. Early atomic clocks were based on masers at room temperature. Since , more accurate atomic clocks first cool the atoms to near absolute zero temperature by slowing them with lasers and probing them in atomic fountains in a microwave -filled cavity.
