Wind Racer (Science)

 Aim: To make the most efficient wind racer which would either go the furthest or looks the most creative.

Equipment: Newspaper, plastic bag, tape, trolley, bamboo/metal rod, skewers.

Method:

• Gather all your equipment

• Set up your trolley and your bamboo stick, by placing the stick in the hole. 

• Cut a plastic bag into a partially large rectangle a size that would suit the stick. 

• Repeat with newspaper or paper. 

• Tape your first rectangle to the rod.

• Repeat with your other material. 

• After use sticks to create a structure for the sail, we used skewers but you can use another material. - Since we used a whole newspaper page, we stuck 2 skewers together from the ends. Making it longer. 

• Stick one pair at the top and another one at the bottom

• Depending on the size of your sail and rod place one or two pairs in the middle too. 

• After, make sure everything is secure by using tape in places that are weak. 

• Finally, decorate to make the appearance look more appealing.

Discussion:  

After building the wind racer, we then went outside for the distance test. We used the leaf blower to move our wind racer. Our wind racer stop at a certain point where the wind of the leaf blower can't reach anymore. We put plastic in front of the cardboard so that it can catch the wind to push it. If we have used the metal stick then probably it could take more air since it's stronger. I forgot to take a picture of our wind racer so I just got a picture from the internet.

Conclusion:

The wind racer that we made turned good, it went pretty far but it stopped because the air of the leaf blower can't reach anymore. We raced with my classmate and I think our wind racer got 3rd/ 2nd place. In design, I think my group and I could still make it look better and make the sail more creative. Anyway, we had fun building our Wind Racer. I hope that if we do it again we will come 1st, and also we might change ours in a different position since our one got stuck in the grass after reaching the capacity of the air from the leaf blower.
