Measurement

Exploring the concept of speed. Students will realise that speed is made up of two measurements, one of distance travelled, and one of time taken. These two measurements can be used to calculate speed, which can be converted to different units.

L.I. Students will be able to 1. Use appropriate scales, devices & metric units for length, area, volume & capacity, weight (mass), temperature, angle and time.  2. Convert between metric units, using whole numbers and commonly used decimals.  3. Use a range of multiplicative strategies when operating on whole numbers.

S.C. We will
 * Calculate speed from measured distance and time
 * Solve multiplication problems using doubling and halving strategies
 * Use know multiplication facts to solve multiplication problems

My Estimation for running km per hour 7km per hour

After the test I have Discoverd that I can run 8 km per hour

media type="custom" key="8887466"

__30.03.2011__

media type="custom" key="8887480" today I ran 100 meters my time was 21 seconds. So if i devided that by 21 it equles 3:33. so if I ran 1,000 meters it would problery take me 3:33. And I would be running 3 meters per second --- __31.03.2011__

1. What speed can a student travel by bike estimation estimation 7mph Actaul

2. How many meters per second can a student travel by bike? estimation 4m Actual

Refletion I still need help with how to convert the time into seconds and minutes. Because I am not sure to use times or devotion --- 1/4/2011
