Measurement


 * __Tuesday 29 March 2011__**

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.

Estimation My estimation for running km per hour 11kph

After test I have discovered that I can run 12kph

time taken 100m=18 seconds

18 secs times 10 = 180÷12=3... 60÷3 3mins 60 ÷3 = 20

1. What speed can a student travel by bike? Estimation: 18kph. Actual: 20kph.√

2. How many meters per second can a tudent travel by bike Estimation: 8 meters per second. Actual: 5.6 meters per second.√

I know that I can calculate the speed that someone is going by measuring how far the distance is and how long it took them. I am still unsure about calculating untidy distances and time because it starts to get hard like in the coast to coast book where you had to answer lots of hard questions and I only got to question 3 in half an hour. The running testing was fun because I worked out that over a kilometer I was running at 12 Kph and over 100m I was running at 20kph and running 5.5meters per second.
