jelly beans experiment

the jellybean experiment we did in class was not scientific. The reason for this is that the experiment was controllable. We had to many variables. This makes it impossible to conclude that the blindfold was the crucial in tasting better. Because in our class the blindfolded people were male and they both smoke. The testpersons that could see were both female and didn't smoke. However we did use the five key steps. We had an observation, hypothesis, experiment. However the last 2 steps of the five were impossible, because of the variables. When we would do this experiment again and take out the gender and smoking variable and maybe age, then it is scientific.
