LESSON 5: ALTERNATIVES TO USING FOOD ADDITIVES FACTORS OF SCIENTIFIC LITERACY AND FOUNDATIONAL OBJECTIVES, LEARNING OBJECTIVES, SCIENCE 10 BIBLIOGRAPHY
NEXT LESSON

DO WE HAVE A CHOICE?

FOOD ADDITIVES ARE USED FOR A VARIETY OF REASONS, SOME OF WHICH INCLUDE:

  • FOOD PRESERVATION
  • MOISTURE CONTENT CONTROL
  • FAVORABLE COLORING
  • FAVORABLE FLAVOR
  • ACIDIC CONTROL
  • ANTIMETABOLICAGENTS OR RIPENERS
  • NUTRITIONAL SUPPLEMENTS

IS THERE AN ALTERNATE WAY TO ACHIEVE THESE RESULTS WITHOUT USING FOOD ADDITIVES?

HERE YOU WILL READ VARIOUS SOURCES FROM THE INTERNET TRYING TO FIND OUT JUST THAT.

ACTIVITY

READ SOURCES ON THE INTERNET TO TRY TO FIND WAYS OF ACHIEVING SIMILAR RESULTS WITHOUT THE USE OF FOOD ADDITIVES. FEEL FREE TO DO YOUR OWN SEARCH. IF YOUR TIME IS LIMITED, YOU MAY WANT TO BEGIN YOUR SEARCH BY CHECKING OUT THESE SITES:

WHEN YOU FIND AN ALTERNATIVE, MAKE A RECORD OF IT AND THE WEB ADDRESS WHERE YOU FOUND THIS ALTERNATIVE.

GATHER YOUR INFORMATION IN A TABLE FORMAT.

AFTER YOU HAVE GATHERED A CONSIDERABLE LIST, CONTACT ANOTHER CLASSMATE WHO HAS ALSO BEEN SEARCHING FOR THIS INFORMATION. COMPARE YOUR LISTS. WHOSE LIST IS LONGER? HOW MANY ENTRIES ARE THE SAME ON BOTH YOUR LISTS? HOW MANY ITEMS DID YOU GET FROM YOUR CLASSMATE THAT CAN BE ADDED TO YOUR LIST? ADD THESE TO YOUR LIST SO THAT BOTH OF YOUR LISTS CONTAIN THE SAME INFORMATION.

YOUR TEACHER MAY ASK YOU FOR A COPY OF THIS INFORMATION.

ASSIGNMENT

WRITE A PARAGRAPH THAT SUMMARIZES THE ALTERNATIVES TO USING FOOD ADDITIVES.

ATTACH YOUR LIST OF ALTERNATIVES FROM YOUR LESSON ACTIVITY.

ASSESSMENT

YOUR PARAGRAPH AND LIST OF ALTERNATIVES FROM YOUR LESSON ACTIVITY WILL BE GRADED. YOUR SCORE WILL BE OUT OF 20 POINTS. 10 MARKS WILL BE GIVEN FOR A FAIRLY COMPREHENSIVE LIST OF ALTERNATIVES; THE OTHER 10 MARKS WILL BE GIVEN ON YOUR PARAGRAPH SUMMARY. YOUR LIST OF ALTERNATIVES WILL HAVE A SCORE BASED ON ITS COMPLETENESS AND CORRECTNESS. YOUR PARAGRAPH SUMMARY MARK WILL BE BASED ON YOUR ABILITY TO SUMMARIZE FACTUAL DATA IN A PLEASING AND GENERAL WAY: CONSIDER SENTENCE STRUCTURE, PARAGRAPH STRUCTURE, ACCURATE REFLECTION OF THE FACTS, AND OVERALL PRESENTATION.
