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.

Specific Expectations

Determine if the children can convert from analog to digital, and from descriptive to digital.
See if they can do any arithmetic with time.

Purpose

To investigate the relationship between the height of water in a container and how fast if flows out.

Material

1. Prepared Water bottle with hole
2. Graduated cylinder
3. Ruler
4. Stopwatch or Wall clock with second hand

Instructions

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.

Specific Expectations

Teach the students how to estimate and measure elapsed time using a stopwatch and the wall clock.

Materials

Stopwatches. Worksheet.

Important Terminology

elapsed time, hours, minutes, seconds.

Background Knowledge

Hook

Lesson Sequence

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:

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.
