Title: Density of Hershey Kisses
Title: Density of Hershey Kisses
Purpose: to determine if all types of Hershey kisses have the same density
Hypothesis:
Materials: several types of Hershey kisses, balance, calculator
Procedure:
1. Determine the mass of each kiss
2. Record in data table
3. Calculate the density of each kiss
(density = mass/volume)
4. Determine average density
5. Repeat with other types of kisses (dark chocolate, hugs, almond, etc.)
6. Construct a bar graph of the different types of kisses
Results: See data tables and graph, below
Discussion:
Summarize what you did
Identify independent and dependent variables, constants, and controls
Compare/contrast the density of the different kisses.
Discuss any similarities or differences you note
Describe your graph, being sure to use data from the graph to support your statements
Identify sources of error and provide suggestions for improvement
Conclusion:
Is the density of the Hershey kisses the same? If so, state this. If not so, then rank the kisses in order of increasing density.
Reflection: Personal statement about what you learned from the lab activity
