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.

My Estimation for running km per hour 14km per hour After test I have discovered that I can run 15km per hour.

15 seconds 1.15X10=150 divided by 60=2.5 2. 100 divided by 15= 6.6 meters per second

Time Taken:1000m=3.05 1. What speed can a student travel by bike. Estimation: 20km per hour Actual:19.67 km per hour

2. How many metres per second can a student travel by bike Estimation: 5 metres per second Actual: 5.4 metres per second

1.To work out what speed a student can travel on a bike I went 60 divided by the time taken which was 3 minutes and 5 seconds which is 19.67 km per hour.

2.To work out how many metres per second a student can travel by bike I went 1000 divided by 185 seconds= 5.4 metres per second.

I now Know that to work out metres per second when you are riding a bike 1km you first need to go 60 divided by the time taken and then you will get your answer.

The F.I.O activity was hard at first but then when I did a few of the questions it became easier because I knew how to work out the answer and get a speed for kmph.
