The parameters of a simple experiment will differ from greenhouse effect on a planetary scale, but the presence of the effect is the same for both the absorption bands specific to the greenhouse gas (and in particular co2) are well established by science.
This activity is a lab where students design an experiment to test the rate of photosynthesis students will analyze data,write a report using the scientific method, and apply results to current environmental issues. Wave-particle duality publicized early in the debate about whether light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well the evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm. A blind experiment attempts to control for bias on the part of the participants and to ensure that a placebo effect will not affect only the treatment group (if the example study was not blind, those not taking zinc may not bother to take their pills or may believe they won't get better because they know they're not taking the good stuff.

Results from numerous experiments show that certain forms of priming occur that are very difficult to occur with visible primes one such example is form-priming, where the prime is similar to, but not identical to the target (eg, nature - mature . Ment can be a test of the effect of different actions carried out by the experimenter or a test comparing differing conditions as some designing an experiment.
