Open System
Imagine doing an experiment to see how light impacts the growth of a plant. One plant is placed in a closet, one is placed in a window sill, and one is placed in a greenhouse. All plants receive the same temperature and amount of water. Identify the independent variable.
Amount of light/Environment of Light
The final step in the scientific method...this tells others what happened in an experiment.
Conclusion

What relationship between heat and bounce height did we discover in the 1.09 Lab?
As heat increases, bounce height increases
