Measurement

__ Tuesday 29 2011 __

Exploring the concept of speed. Students will realize 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.

What speed can a student travel by bike. The time taken was 3 minutes and five seconds. (03.05)

Estimation: 14km Actual: 19.67km

I worked this out by going 60 ÷ 3.05 = 19.672

How many metres per second can a student travel by bike?

Estimation: 6.2 Actual: 5.4

I now know that to do how many metres per second that you don't enter the minutes in the calculator, you convert it into seconds.

I found that the activity we did in the figure it out book years 7 - 8 was quite tricky and required a calculator.

The most that i would need help on is converting the numbers.
