Objective 1

The student will demonstrate an understanding of the nature of science.

(6.1, 7.1, 8.1)

In this lesson Homemade Soap will be prepared, then tested to determine its pH and to see how well it lathers and cuts through grease. These properties of the homemade soap wil be compared to those of a commericial soap sample to see how well it performs. Students will be required to complete a formal lab report in which they will use as part of the information in their commercial.

Students will then be expected as their culminating task to deveop a commercial to market their soap. Each group will present their commercial to a panel of three persons. The persons will be adults (teachers, administrators, directors etc.)

1. What is Soap?

2. What is the History of Soap?

3. How do Soaps work?

4. How is soap made?

5. What chemicals are used to make soap?

6. What is the most dangerous part of the lab?

7. Why is it critcal to follow safety rules?

8. Do you think Homemade Soap would sell?

9. What are important properties when people buy soap?

10. Can I create a soap product that is marketable and appealing to the general public?

1. Students will be instructed in detail on Safety and Equipment use:

Trustworthyness- Do your own work do not copy from other groups. Do your part of the lab. Be safe when conducting lab, the teachers and lab partner can trust you will use chemicals and equipment  correctly. other groups should be able to trust that you will do the right thing.

Respect-Respect your partners ideas and have good manners. Respect chemicals and equipment. Respect other groups.

Responsibility- Be responsible about lab work and have Commerical ready to turn in on time. Follow all safety rules and use chemcials and equipment correctly.

Fairness- Share lab duties such as clean up.

Caring-Work with your lab partner and help each other in need be. Care about other groups around you.

Citizenship-Follow all safety rules and dispose of chemcials correctly

2. Students will begin formal lab report. The lab report will be written with lab partner: Problem, Rsearch (History of Soap Making), Materials/Equipment &Procdures

3. Students will create soap product.  Data

4. Students will test homemade soap against commercial soap. Data

5. Students will complete lab report- Results and Conclusions

6. Students will write a product description and create a commerical to market thier soap product. Final Activity  (See Rubric For Details)

Knowledge- Students will be able to identify how soaps work and their history.

Comprehension-Students will demonstrate how soap is made through conducting a Soap Making Lab.

Application- Through the formal written  lab report students will be able to communicate their  results.

Annalysis/Synthesis- Students will examine the pH, Lathering Ability, Behavior of Soap in Hard Water, and Ability to cut through Grease of thier homemade soap and commercial soap.

Evaluation-Through the commerical presentation students will be able to tell why their soap is more marketable.

Teacher will modify groups according to learning levels group a weak with a strong student. Teacher will guide as needed.
