Learn Alberta
Demonstrate to the Students how to get to the 24 hour clock lesson on the Learn Alberta website. Take them to the computer lab and have them go through the exercise online.
The website also has other lessons applicable to this unit. If time permits, have the students go through those lessons for extra practice.

Remember: 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day.
How to add and subtract time.
Suppose Rilie studies from 3:48 to 7:05, how would you go about calculating how long he studied?
One way is to do addition. He studies 12 minutes to get to 4:00, plus 3 hours to get to 7:00, plus 5 minutes to get to 7:05, for a total of 3:17. This same method can be extended to include seconds, or even days and years.
Determine if the children can convert from analog to digital, and from descriptive to digital.
See if they can do any arithmetic with time.

To investigate the relationship between the height of water in a container and how fast if flows out.
Repeat the following steps with the bottle starting with different water levels in the bottle. For example, nearly full, half full, and nearly empty. Collect additional data for other water levels as time permits. The more data the better.
Teach the students how to estimate and measure elapsed time using a stopwatch and the wall clock.
Stopwatches. Worksheet.
elapsed time, hours, minutes, seconds.
Talk about seconds - how short they are. Ask when you would want to measure time that accurately.
Have students close their eyes and time out 10s. ask if they thought it was longer and shorter
Brainstorm how to estimate time eg 1 mississippi.
Draw a digital clock to show each of the following times:
| a) quarter to 4 | b) 21 minutes after 8 |
| c) 9 minutes to 1 | d) 25 minutes before 4 |
If you have 45 minutes of homework, when is the latest you can start so that you will be finished in time to watch Heros at 8:00 pm. Show your thinking.
If you started this test at 12:15:05 and finished at 12:19:23,
a) how long did it take you? Show your work.

Talk about the history of water clocks. http://en.wikipedia.org/wiki/Water_clock
Relate this to how the Greeks used the water clock to limit debate in public life.
Discuss how the Greeks divided the day into 12 hours, so they changed length as the seasons changed.
Show the Tower of the Winds in the Agora. http://en.wikipedia.org/wiki/Tower_of_the_Winds
10 min - Divide the children into groups. Ensure each group has a heterogenous mix of students. Introduce the experiment. List required information to be gathered for the lab report.
To teach the children to relate the 12 and 24 hour clocks, to measure time intervals to the nearest second, and to determine elapsed time.
elapsed time, millennium, century, decade, year, month, day, hour, minute, second
