Lab Report
Ionic and Covalent Bonds
This lab report is for you to reflect on what you completed and learned in this simulation, and to practice your
written scientific communication skills. Include enough detail to clearly describe the lab experience to someone
who understands the concepts but has not participated in the simulation. Use correct scientific terminology
whenever applicable.
Sections
1.Describe the overall objective and make a hypothesis
2.Introduce relevant background knowledge on this topic
3.Summarize the steps taken in the simulation
4.Explain any obtained results
5.Discuss the conclusions and implications

1.Describe the overall objective and make a hypothesis.
What is the overall purpose of the experiments or activities? Make a hypothesis. Recall that the hypothesis is a
claim that answers a question or makes a prediction about an event that has not yet occurred.
Hint: The purpose is often stated in the welcome message of the simulation (as shown in the example image
below).
For your entry make sure to include the following:
● Include one statement that describes the overall objective in your own words.
● Include one statement that describes the hypothesis.
Objective
Explore the properties of chemical substances that can be used to identify the types of bond in a chemical
substance using a laboratory procedure.
Hypothesis
If a substance is solid at room temperature and has a crystalline structure, dissolves easily in water and conducts
electricity then it possibly has ionic bonds otherwise it possibly has covalent bond.

2. Introduce relevant background knowledge on this topic.
What have you learned in class or researched on your own that would help prepare for this simulation?
Hint: You can review the “THEORY” section in the simulation (as shown in the example image below)
For your entry make sure to include the following:
● Include at least three important details from the lab “Theory” tab, the Lab Manual, or other resources, in
your lab report that support the simulation activity.
Controlled Variables
Water stirring duration, amount of substance.
Dependent Variables
State of matter, texture, appearance, solubility in water, crystalline structure, type of bonds (whether ionic or
covalent)
Independent Variables
Different substances

sodium chloride
1. State and appearance
2. Determine solubility in water
3. Determine conductivity

4. Determine whether the substances are ionic or covalent
4.Describe any obtained results.
Explain all obtained results. Were these results expected or unexpected?
Hint: You can use the “MEDIA” tab in the Lab Pad to revisit relevant images from the simulation (as shown in the
example image below).
For your entry make sure to include the following:
● Document the results from the simulation.
● Document whether the results were expected or unexpected, and briefly explain why.

conductivity in water)

5.Discuss the conclusions and implications.
How do your results relate back to the original purpose and your hypothesis? Were there any systematic sources of
error that could have affected the results? What did you learn?
For your entry make sure to include the following:
●
● Include a statement that briefly summarizes how the results of the simulation relate back to your original
purpose and hypothesis.
Include a statement that details any systematic sources of error you identified that could have affected
the results. If the lab did not have any systematic sources of error, include a statement that
acknowledges the lack of error present in the lab.
● Include a statement about what you learned from the simulation.
Conclusion
You can identify the types of bonds contained in a substance by comparing and contrasting properties common
in Ionic and/or Covalent compounds.
If a substance is solid at room temperature, conducts electricity, has a crystalline structure and dissolves easily in
water, then it most possibly has ionic bonds, if otherwise it most possibly has covalent bonds.
