The problem: What is the relationship between mass added to a spring and the length of the spring.
Independent Variable: Mass added to the spring.
Dependent Variable: The length of the spring.
Controls: Spring, Position of the spring.
Procedure:
1. Set up spring on the side of the table with the spring hanging down over the edge. The position of the spring should stay the same to increase accuracy.
2. Add various amounts of weight onto the spring in increasing increments. The weights added are the independent variable and are what is being tested for. Weight amounts should range from 10 grams - 1100 grams or whatever the max the spring can hold without touching the floor.
3. Measure the length of the spring in centimeters by placing the meter stick right next to the spring and making sure that 0 is lined up with the top of the spring for more precise measurements.
4. Record the data for every different weight on.
5. Repeat until a satisfactory amount of trials have been performed

Raw data
Amount of weight: Length of spring:
0 grams 10.4 cm
10 grams 10.4 cm
20 grams 10.5 cm
30 grams 11.2 cm
40 grams 11.4 cm
50 grams 11.5 cm
100 grams 14.4 cm
200 grams 24.3 cm
250 grams . 28.5 cm
300 grams 32.7 cm
400 grams 41.4 cm
500 grams 50.6 cm
600 grams 59.3 cm
1000 grams 93.4 cm
1100 grams 102.25 cm
An equation that would equal this is that: Length= 10.86895652 * weight + 0.
Data was collected by measuring the length of the spring based after the mass was added to the end of it using a meter stick. Some sources of error in the collection were:
The bouncing of the spring
Time constraints for only one trial.
Some sources of uncertainty were the parallax of the person measuring the length as well as the spring going down further than a meter once the most weight was put on.
In conclusion the more mass added to the end of the spring, the longer the spring seemed to stretch. This seems to be at an linear growth with the growth steadily increasing in correlation to what the weight did with a 10.86895652 grams/centimeter change. This can show a direct correlation between the amount of mass on the end of the spring and the length of the spring. The most uncertainty in this experiment was trying to find accurate measurements based on the perception of the meter stick as well as the bounciness of the spring making a measurement possibly vary. A way to improve this would be to wait for the spring to stop bouncing and be eye level with the bottom of the spring. In the future with more time and more trials then that would be a more efficient ways to collect data. However, the conclusion would most likely remain the same with the mass added to the spring and the length of the spring being directly proportionate as shown in the graph.
