Science and Our Food Supply: Investigating Food Safety from Farm to Table

36

MIDDLE LEVEL

ACTIVITIES & LABS

Module 3 activities and labs continue the exploration of  

bacteria by investigating how pasteurization and other technology  

are used during processing to improve food safety.

Blue’s the Clue 

— introduces pasteurization and the 

effect temperature has on reducing and controlling the 

growth of bacteria. 

Time to Tune In  

Dr. X takes students into the  

research lab to explore the role  

science plays in food processing.

 

Mystery Juice 

— uses investigation to demonstrate 

how pasteurization reduces the number of  

microorganisms in juice. 

Ultra High Pressure Treatment 

— shows how foods 

are kept safe through processing, including one of the 

newest food preservation technologies.

Time to Tune In  

Students revisit the research lab and 

consider the roles of pasteurization, 

irradiation, and ultra high pressure 

treatment in keeping food safe.
