2. A scientist is investigating how different wavelengths of light affect the rate of photosynthesis in algae. What is the dependent variable in this experiment?
Wavelength of light
Rate of photosynthesis
Type of algae
Temperature
3. The dependent variable is the variable that is or measured in an experiment.
4. In an experiment, the dependent variable's value on the independent variable.
5. Design a simple experiment to investigate the effect of different amounts of sugar on the growth of yeast. Clearly identify the independent variable, dependent variable, and at least two control variables.
6. Explain why it is crucial to measure the dependent variable accurately and precisely in scientific research.
7. The dependent variable is the factor that the experimenter changes or manipulates.
