Students examine how a rate is calculated from two points. Using battery operated cars, pairs of students measure time and distance. Afterward, they use this data to calculate the rate. Students then plot four ordered pairs and discover...

Students determine how to find North using a watch and their shadow. For this finding North lesson, students go outside on a sunny day and work with their shadow and a wrist watch to find out which direction that North is. They examine...

Students discover time pieces and complete telling time activities. In this time lesson, students complete a worksheet about what make a clock keep time. Students watch a video about time and clocks as well as a video about an Egyptian...

Students answer questions about the clock.  In this time lesson plan, students answer questions using intervals of five minutes. Students solve problems about how long to the next activity, how much longer, and whether or not we...

Fourth graders discover time keeping by analyzing technological advances in history.  In this time lesson, 4th graders create and complete a KWL chart based on their research of a famous timekeeping invention, such as a sundial....

Math was easier before it got mixed up with the alphabet. A 10-page test covers material from multiple years of high school math. Scholars demonstrate knowledge across domains with a mixture of short answer and applied problems.

Students estimate what they can accomplish in a minute. In this estimation lesson, students guess how many jumping jacks or stars they can draw in a minute. They get timed and see how close they are to their prediction. 

Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an...

Students participate in a variety of center activities to reinforce the concept of days of the week and their succession. The concept of time can also be taught at the same time to introduce timekeeping.

Students become aware of the effects of tides on the Earth's rotation. In this tides lesson, students calculate the number of seconds lost over various periods of time.

In this tower building and budgeting instructional activity, students attempt to meet the goal of building the tallest free standing structure on the smallest budget. They build the structures with straw, paper clips, and masking tape...

Learners demonstrate basic construction skills by building a free standing structure. They compute the cost of the structure.

Students predict, then measure how far a bug can travel on a "course" over a specified amount of time, then construct graphs based on the data they acquire.

Students investigate how to create a free standing structure. In this mathematics lesson, small groups of students demonstate how to build the tallest structure while spending the least amount of money on materials.

Students demonstrate basic construction skills by building a free standing structure, using predetermined materials. They compute cost of structure by using multiplication skills or calculator.

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which...

Get the official U.S. time from the official U.S. timekeepers, the National Institute of Standards and Technology (NIST), and its military counterpart, the U.S. Naval Observatory. Java needs to be enabled to see the timeclocks. There are...

The concept of a year in time and the various kinds of year used in human timekeeping are discussed.
