This chart shows the experimental design of four students who are all observing what kind of bird seed birds tend to eat more often.
Student 1 Student 2 Student 3 Student 4
- Performed the experiment once
- Used the same area, same time of day, and same amount of seeds
- Repeated the experiment 5 times
- Used the same area, different time of day, and different amount of seeds
- Repeated the experiment 2 times
- Used the same area, different time of day, and different amount of seeds
- Repeated the experiment 5 times
- Used the same area, same time of day, and same amount of seeds

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
