This experiment investigates the effect of tonic water on Jello. It includes problem identification, research on tonic water, hypothesis formulation, experimental procedures, variable control, observations recording, conclusion drawing, and the importance of repeating the experiment to ensure accuracy.
E N D
I. Problem: Stating the problem. Written as a question
There’s Always Room for Jello I. Problem: How does tonic water affect Jello?
II. Research: Gathering information on the problem
II. Research: Tonic water is carbonated water flavored with quinine. Quinine is a bitter alkaloid from the bark of the cinchona tree and gives tonic water a bitter taste. Quinine has a property of fluorescence, which means that it glows when exposed to special types of light.
III. Hypothesis: Write what you think will happen during the experiment. It is your educated guess about the outcome of the experiment. Written in an If I test ….. then I think ….. statement
III. Hypothesis: If I make two batches of Jello, one with tap water and one with tonic water, then I think…
IV. Procedures A. Steps to be followed: the steps for conducting the experiment
Procedures A. Steps to be followed: 1. prepare two boxes of Jello according to the package. 2. For one box, make it with regular tap water. For the other make it with tonic water. 3. Chill overnight and observe the next day. 4. Write observations.
B. Materials: a list of all materials needed during the experiment
Materials two boxes of Jello, same color water tonic water two pans hot plate measuring cup spoon
C.Variables: two types of variables being tested. Control variables are all the parts of the experiment that stay the same for both sides of the test. The Independent variable / manipulated variable is the one thing being tested in the experiment.
Variables Control Variables Independent variable
V. Observations Scientists must observe the experiment and write down important information. Sometimes experiments can be recorded in a chart or graph. You need to draw the chart or graph before conducting the experiment.
VI. Conclusion: State if the experiment supported or did not support your hypothesis. Write in complete sentences. You must include data in this discussion.
VI. Conclusions: The jello lab did/did not support my hypothesis…
VII. Repeating the work: Repeat the experiment many times to be sure the data is accurate. An experiment must be conducted by other scientists before it is considered to be accurate and to be valid new scientific research.
VII. Repeating the work: After completing four trials of the above experiment, the data…
