Question: What is the density of an orange? Is an orange more dense with the peel on or off? 1. Background: What do we know about oranges? Tell me everything you know about oranges

that may be important to consider with relation to density of oranges. How must we find the density?

2. Hypothesis: Which is more dense? Will either of them float?

3. Procedures: Write procedures below

4. Experiment: Perform the experiment you wrote and record the data on the chart. 5. Represent the Data: Take the data from the chart and graph the average

density of peeled and unpeeled oranges6. Analysis and Conclusions: Answer the questions

Conclusion Questions1. Were you right with your prediction? Did any of them sink? Float?.

2. Do you think all fruits with peels will have similar results to an orange? Give two reasons to support your answer.

3. How do you think the density of a fruit like this effects the cost of the fruit? Explain.

4. Graph the results of the density of the average peeled and the unpeeled oranges. Don’t forgetto give your graph a title, label the X & Y axis’, make a key and label it! Your graph should be neat!
