The document describes a procedure to test how different types of string affect the rate of fall of a toy firefighter parachute. Materials like a trash bag, string, and toys are used to create parachutes with different strings and dropped from a meter stick ladder. The time taken for each parachute to fall is recorded, and the results show that thicker strings like pipe cleaners allow for faster fall times than thinner strings like ribbon or yarn.

2. Cut a 10-inch diameter circle out of a trash bag; poke 4 holes in it, equal width apart. Cut 4 12-inch segments of the yarn, and tie them each to the trash bag, using the holes that you poked in it. Then tie the ends of the 4 strings to a firefighter.

3. Fold the circle in half and cut a hole, the shape of a heart, in the middle of the trash bag. Set the ladder up, get 3 meter sticks, taped together, and get the stopwatch prepared.

4. Climb the ladder, 3 meters sticks high, and drop the parachute from the top, with the guy equal to the top of the 3rd meter stick. Record how many seconds it is airborne using the stopwatch.

5. Repeat step 4 twice.

6. Repeat steps 2-5 three times with the 3 different types of string.CONCLUSION:)<br />C: We can claim that the thicker the string (IV) the faster the parachute falls (DV.)<br />E: The pipe-cleaners (the thickest string) average was 1.6 Seconds compared to the ribbon (the thinnest string) average (2.82 seconds) and the yarns (in the middle) average (2.69).<br />R: The thicker the string, the less time it takes for the parachute to fall because the weight is pulling the parachute down faster.<br />
