Title:
Synthetic vs. Natural: What's the Best Choice?
Digital Tool/Resource:
One-Third of Cancer Patients Use Alternative Medicine
Web Address – URL:
Overview:

In this activity, students will investigate the effectiveness of a pharmaceutical medicine and its natural counterpart.  They will evaluate the pros and cons of each and make a recommendation about the best choice for the consumer.  Students present their research to the class and evaluate the research of their peers.

This activity was created as a result of the Alex Resource Development Summit.

NAEP Framework
NAEP Statement::
P8.4a: Elements are a class of substances composed of a single kind of atom.

NAEP Statement::
P8.4b: Compounds are composed of two or more different elements.

NAEP Statement::
P8.4c: Each element and compound has physical and chemical properties, such as boiling point, density, color, and conductivity, which are independent of the amount of the sample.

  • Synthetic
  • Natural resources
  • Society
Knowledge:
Students know:
  • A molecule is formed when two or more atoms join together chemically.
  • A compound is a molecule that contains at least two different elements.
  • All compounds are molecules but not all molecules are compounds.
  • A mixture consists of two or more different elements and/or compounds physically intermingled.
  • A mixture can be separated into its components by physical means, and often retains many of the properties of its components.
  • A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.
  • A solution consists of a solute and a solvent. The solute is the substance that is dissolved in the solvent.
  • Synthetic materials are made by humans.
  • Synthetic materials can be derived from natural resources through chemical processes.
  • The effects of the production and use of synthetic materials have impacts on society.
Skills:
Students are able to:
  • Articulate a statement that relates a given phenomenon to a scientific idea, including the differences among compounds, mixtures, and solutions.
  • Identify and use multiple valid and reliable sources of evidence to construct an explanation differentiating among compounds, mixtures, and solutions.
  • Use reasoning to connect the evidence and support an explanation of differences among compounds, mixtures, and solutions.
  • Identify and describe the phenomenon under investigation, which includes the differences among compounds, mixtures, and solutions.
  • Identify and describe the purpose of the investigation, which includes providing evidence of differences among compounds, mixtures, and solutions.
  • Collect and record data, according to the given investigation plan.
  • Evaluate the data to determine the differences between compounds, mixtures, and solutions.
  • Obtain information about synthetic materials from published, grade-level appropriate material from multiple sources.
  • Determine and describe whether the gathered information is relevant.
  • Use information to illustrate how synthetic materials are derived from natural resources.
  • Use information to illustrate how synthetic materials impact society.
Understanding:
Students understand that:
  • Compounds, mixtures, and solutions can be differentiated from one another based on characteristics.
  • Synthetic materials come from natural resources.
  • Synthetic materials have an impact on society.

Alabama Alternate Achievement Standards
AAS Standard:
SCI.AAS.8.3- Differentiate between compounds and mixtures.
SCI.AAS.8.3a- Recognize that synthetic materials are made from natural resources; identify a synthetic material and the natural resource from which it is derived.


Learning Objectives:

1.  Students will be able to explain how synthetic products are made from natural resources.

2.  Students will be able to evaluate the effects of synthetic and natural products with similar functions to determine the best consumer choice.

3.  Students will create and present a poster to express their evidence-based opinion.

4.  Students will write reviews of their classmates' opinions.

  Strategies, Preparations and Variations  
Phase:
During/Explore/Explain
Activity:

1.  Students will watch the video clip "One-Third of Cancer Patients Use Complementary or Alternative Medicine."

2.  Student groups draw cards for assigned synthetic/natural product pairs using the Product Cards.

3.  Using digital devices with internet access, students work in groups to research their product pairs by referring to their Research Guide.

4.  Student groups make a poster which shows the pros and cons of the natural and synthetic medicines in their assigned product pair and makes a recommendation about which remedy is the best choice.

5.  Student groups present their posters to the class.

6.  Students engage in a gallery walk with other groups' posters and write reviews using the Project Review Form.

Assessment Strategies:

Student posters and presentations are evaluated using a rubric.

The rubric assesses student posters, presentations, and written reviews of other projects.


Advanced Preparation:

Project cards will need to be printed and cut out ahead of time. The project cards can be laminated for longevity.

Student Project Review Forms will need to be printed out ahead of time.  An alternate method is to write the sentence stem on the board or chart paper and students can copy it onto their own paper as many times as needed.

Rubrics need to be printed and cut apart.

Students will need access to digital devices with internet access.
