Instructional Ideas
  • Conduct demonstration extractions on processed plant-based foods like corn chips and have learners tell if they think DNA will be present or not
  • Spend extra time on the pre-lab activities if the class is less familiar with cells and organelles
Classroom Considerations
  • Invest in thicker Ziploc bags, as thin bags may rupture when pupils are mashing their fruit samples

  • Teacher's guide includes all printable materials, answer keys, and clear instructions
  • The procedure is simple and easy to understand and execute
  • Pre-lab assignments provide individuals with an understanding of how scientists use both manual and chemical techniques to remove DNA from the cell 
  • None
