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.

__31.3.2011__ Time taken 1000m= 3.20minuts 1. What speed can a student travel by bike Estimation: 20km per hour Actual: 60min divide 3.20= 18.75 kmph 2. How many meters per second can a student travel by bike? Estimation: 8 meters per second Actual: 1000 divide 192=5.2 mps Reflection: I know now that I really should work on my measurement skills. I am still unsure of the procedure that you have to do on your calculator. I still need help with getting it sussed. The Fio activity was really quite hard and I would like to go over it again to clarify some things.
