I am asked to write a hypothesis and null hypoothesis on an experiment im doing using different color cellophane pieces, solar cells, and a motor fan. Are these considered a hypothesis and null hypothesis? Hypothesis: Placing colored films on the solar cell will have a positive or negative effect on the power output and affect the fan's speed being faster or slower based on the color of the film. Null Hypothesis: Colored films have no effect on the power output of solar cells and fan speeds remain the same.

Lab students placed ten spinach leaf disks in each of three test tubes containing a baking soda solution and a control tube without baking soda. The volume of liquid in each tube and the temperature of the solutions were held constant. All tubes were placed an equal distance from a light source as indicated in the accompanying table. After 10 minutes, the amount of oxygen present in each sample was measured.
