Gummy Bear Lab The purpose of this lab is to learn how to set up a lab report and properly use the Scientific Method. Question/Purpose: What will happen to a gummy bear when you put it in water over night?Hypothesis: (use IF, THEN format; give rationale for hypothesis)________________________________________________________________________________________________________________________________________________________________________________________________________________Materials (create a bulleted list of ALL materials used, include quantities)* Plastic Cup* Gummy Bear* RulerProcedure (written as step-by-step directions)Make qualitative observations and record on separate sheet. Use the data table to show your qualitative observations (for day 1 and day 2).Make quantitative observations (length, width, thickness, volume, mass and density) and record on a separate sheet. Use the data table to show your quantitative observations (for day 1 and day 2).Label plastic cup with your name and class hour. Add 50 ml of water to the cup. Place the gummy bear in the cup.Leave cup to sit for 24 hours.The following day redo all observations and record in tables.Data: (include both qualitative and quantitative, show both in table format)Qualitative Data - OBSERVATIONSHeadings include: day, looks like, smells like, feels like, otherTitle: _______________________________________Day Looks LikeSmells LikeFeels LikeOther, Color, markings, etc12Quantitative Data- MEASUREMENTSHeadings include: day, length (cm), width (cm), thickness (cm), volume (cm?), mass (g) density (g/cm?)Title: ________________________________________DAYLength (cm)Width (cm)Height (cm)Volume (L x W x H)Mass(g)Density(D = m/v)12Create a GraphCreate a graph that visually represents your data. Your graph must include the following: a title (dependent and independent variables), x and y axis labeled with units, key (if needed), use of color.Title: _______________________________________________________________ Conclusion: (restate your hypothesis and explain if you were correct or not)The hypothesis was ______________________________________________________________________________________________________________________________________________________________Analysis: (this explains what your data means, it MUST include the actual data from your experiment, ANYTHING you say MUST be backed up with supporting data)Some questions you may want to answer in this section would include:Which change is greater, volume or mass? What explains this? Was there a change in density? Why? How do your results compare to other results? What do the results tell you about Gummy Bears and water? REMEMBER include all data to back up your “opinions”.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Possible errors (list at least three things that may have skewed your results)***Suggestions for further study (what ideas did this experiment open up for further study or investigation?) ................
