Wind Racers

 Aim: To make a wind racer

Research: 

Equipment: 

Trolley, 

Bamboo/metal rod, 

Cardboard, 

Newspaper, 

Tape, 

String, 

+ Plastic bag

+ popsicle stick

Method:

Step 1:

Get the metal rod or bamboo stick and put it into your trolly this is your mask.

step 2:

Put down 3 pieces of cardboard into a triangle shape. Fill in the centre of the triangle with paper to make your sail.

step 3:

Connect your sail to your mask using tape.

Step 4:

Add more paper to add extra support.

Step 5:

Using two popsicle sticks make a smaller mask.

Step 6:

repeat step 2 and 3 to a smaller scale but use a plastic bag and connect the two mask using string.

I'll send photo LATER

Discussion: 

Thrust, drag, lift and weight was demonstrated in making our wind racers. When we were making out wind racers we had to make sure the wind can get picked up by the sails so that it could thrust forward, and we had to make sure that there's not too much weight so that it could thrust more. Lift and weight were mostly not shown on this because of this being on the ground.

Conclusion:

Our wind racer did actually work, it picked up the wind very well the only thing I would change is to add another sail so that it could be better and move.
