From the Windmill to the Wind turbine

Constructing a wind turbine

Key words: taller, scale, math,  comparisons, analogy , windmill, wind turbine, wind power alternative sources of energy

 Given that a windmill is 6-7m tall and a wind turbine is 100-110m tall,  we constructed a windmill using paper rolls (recycling).
Problem: If we wanted to construct a wind turbine, how much taller than the windmill would it be? (in analogy)
1.brainstorm -estimations- hypothesis......
2. procedure- action...

Fig. 1  let's place 15 paper rolls the one on the top of the other!

Fig. 2  hmmm... our construction is hard to stay put....

fig. 4 the analogy is obvious

Fig.3  let's transform our measuring! We are going to do the same thing on the floor!

fig. 9 In comparison with us...

fig. 10  paper tape is our best friend!

3. Results.....

fig. 13 the results

4. Conclusion...... muchhhhhhhh taller!!!!!!!
