Method

Materials required:

• Cotton, paper, cardboard, wool, calico/velvet (need to measure dimensions)
• Sticky tape or glue
• Skewer sticks
• String
• Tape measure

Method:

1. Make a cross with the skewer sticks with the short stick across the longer stick like in the diagram below.
2. Tie a string where the two sticks intersect to secure its shape and so it won't fall apart. You can put some glue so that it is easier to stay together.
3. Cut a little notch at the end of each stick so that a piece of string can fit through. After cutting, loop the string all around the cross so it makes the outline of a kite. See diagram below. The string has to be tight but not tight enough to bend the sticks.
4. Place the material over the kite and leave a margin of around 2-3cm and warp it around. Stick the material down by using tape or glue.
5. Loop another string down the back of the kite but leave a few metres extra hanging off the edge. This excess string is the "tail" of the kite where you hold on while it is in the sky.
6. Repeat steps 1-5 for each kite but with different materials.
7. Fly each kite and record each kite's height while flying.
8. Repeat experiment to verify.
9. Compare results and tabulate and/or create graphs showing similarities and connections between results.
