Boys and Girls~ I’m writing to ask your help. You know me as a bear that is squeezable, fruity, and good to eat. I’m looking for more in life though! I want to be fierce and respected like the polar bear. To become a member of the Polar Bear Club I need to get my feet wet. I’ve never been swimming though! Could you help me out? I’m going to test my water skills by getting in water for three hours, twelve hours and for one last test I’ll try twenty-four hours. At the end of each time frame, I will evaluate how well I handled the water. In the end I’d like you to tell me whether you think I could handle life as a polar bear. Thanks for all your help! Gum E.

Bear Going Gummy! Objective: Apply the scientific method and the SI system of measurement to investigate a problem. You will apply the scientific method to determine how a gummy bear’s measurable properties are affected by soaking the bear in water for different amounts of time. Use the correct lab report format to demonstrate the following skills: Identify all the experimental components of this lab Describe the tools and techniques necessary to measure the mass, volume, and density of irregular shaped objects using the SI system of measurement. Use charts to organize your data in a meaningful way. Use graphs to illustrate your data. Write a detailed analysis to explain how mass, volume, and density relate to the gummy investigation. Tips to remember for each portion of your lab report: Problem: Write it in the correct question format. Hypothesis: Use the correct format to express your prediction. Procedure: Identify your parts of the experiment (independent variable, dependent variable, constants, control) and explain how you measured mass, volume and density (include tools & procedures). Data/observations: Show your data in chart and graph form. You should show calculations for volume & density within the appropriate columns of your data table. Analysis: Write a thorough analysis of what happened to your gummies after soaking in water. Describe what happened to the mass, volume, and density of the bears as they sat in water for different time lengths. Support your statements with proof from your data. Conclusion: Write a response to Gum E. Bear explaining whether you think he can live the life of a polar bear. Remember to explain what happened to the gummies’ mass, volume, and density as they soaked in the water. Develop an explanation for why the mass, volume, and density changed the way that they did. Use your data to explain how the composition of the gummies changed over time. In addition, tell Gum E. whether he’ll still have his fruity flavor. Make this determination without actually tasting them. Support your answer with your findings. HAVE FUN!

A separate graph is made for mass, volume, and density. 5 Axes are accurately labeled. Increments are consistent. 5 Mass, volume and density are properly plotted. 5 Analysis accurately describes the change in mass, volume, and density over time. 5 Analysis statements are supported with evidence from your data. 5 Conclusion is written as a letter to Gum E. Bear, and clearly states whether he can live the life of a polar bear based upon your findings. 5 Conclusion provides reasonable explanations to account for the change in mass, volume and density. The fruity flavor is addressed. 5 Conclusion answers the problem and is supported with evidence from data. 5 Student was not sited for safety violations. Total Points 10 100 Teacher Evaluation
