This document provides instructions for making a simple wind speed indicator using a pin, pencil, straws, and cups. It explains that the pin is placed in the pencil eraser and the straws are taped together and inserted into cups with holes. This assembly is used to count how many times the pin spins to measure wind speed outside on different days. The document also briefly discusses other methods of measuring wind speed, like the Beaufort scale, and provides some additional wind-related facts.

1. How can the speed of wind be measured? By: Lili & Julia

2. Materials Pin 2 Straws 4 Mini cups A Pencil Scotch Tape

3. Our First Step First we took the pin and stuck it in the eraser of the pencil.

4. Our Second Step Next we used scotch tape and taped two straws together in the center.

5. Our Third Step Then we put holes in the cups and stuck the straws in the holes. Then we put the pin in the center of the straws and in the eraser.

6. Then to test the speed of wind, we went outside and went to the corner of Johnston and Philadelphia street. On the next slide try and count how many times it goes around. But sometimes it can be a little tricky! Our Fourth Step

8. How many times it went around Friday Saturday Sunday 1 2 3 4 5 6 7 8 9 10 11

9. How you can measure the speed of wind Well you can make something like we did or you could do this one:

10. Speed Of Wind

11. One Kind of a Beaufort scale

13. The wind blows because air has weight

14. Cold air weighs more than warm air

15. Wind forms when cold air meets warm air

16. Heat makes air start moving!

17. Wind blows heat away from your body

19. Lili: To me the bible verse means that God is the most amazing person in the world and can do what he wants to do. Julia: To me it means God is ever where we look and go and he can do what ever he feels like doing.
