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

Solve The Mystery 

6. 

Now ask the students to solve the second part of the 

mystery by asking: Which juice is safe to drink …  

and why? 

7. 

Ask each team to design a lab to provide evidence for 

which juice is safe to drink. You may want to review 

pasteurization with the students. Students can use 

materials and equipment on the lab table. 

8. 

Challenge students to develop their experimental  

designs complete with a control (in this case, a  

standard of comparison). 

9. 

If your students come up with a variety of ways to 

determine which juice is safer to drink (pasteurized), 

that’s great. Go for it!
