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
