Question

Name: Section: Scientific Methodology Worksheet Activity I. My flashlight doesn't work (a very simple example) It is sometimes difficult to distinguish berween a hypothesis and a prediction. This short exercise will help you understand the difference Flashlight Observation. Suppose you find a Bashlight and you try to turn it on and it does not work. Flashlight Question. An obvious question is, "How come my flashlighe doesnt work?" Or "What is wrong with my Bashlight Flashlight Hypothesis. Remember, a hypochesis is a tentative answer to your question that is testable and falsifiable. So. Add two more possible answers to the question "what is wrong with my flashlight?" 1. The builb is burned ut Pick one ofYOUR hypotheses to test. Put a star #2 or #3). next to the hypothesis you are going to test (either Flashlight Prediction. Based on the hypothesis you have chosen to test, what could you do to test this hypothesis And what would you expect to occur? Phrase your prediction in an IF-THEN" statement. For example, IF the bulb is burned out and I replace the bulb, THEN the flashlight will work Stäte your prediction based on the hypothesis you are testing

Explanation / Answer

Although the question does not pertain specifically to the subject of biology, it is being answered as it is a part of "Scientific Methadology" which can find connections to all branches of science including biology

Solution :-

(Q) Add two more possibilities to "What is wrong with my flashlight" .

Ans. Well, anything which you can imagine happened to the flashlight is correct. Ex - There is no bulb in the flashlight, It does not have batteries inside etc.

(Q 2) Ans. We will be testing the hypothesis that "The Batteries are dead"

If the batteries are dead, Then replacing the batteries with new ones (which have been tested) will make the flashlight work

Activity I Reflection Questions

(1) Prediction - It is can be said that it is a guess that is widely accepted outside of science

Hypothesis - A reasonable guess that is used predominantly in science. A Hypothesis goes further than a prediction. You need observations to hypothesize, consider what might happen and why is it happening and make a testable investigation.

(2) Though replacing the batteries may have made the flashlight to work, that does not mean that the flash light is working just because of the replacement of the batteries. Though it is the highly probable case, there may have been other changes which might have happened while changing the batteries which may have rectified the original fault and led to the working of the flashlight.

(3) Because it is not a reasonable guess and there seems to be no basis of the formulation of such a hypothesis. Also there is no way to test the hypothesis.

(4) If the flash light does not work after conducting the experiment, it implies that the hypothesis is wrong. Then based on this information and also other information from observations, a new hypothesis will be formulated and tested.
