CHEMISTRY & AGRICULTURE LECTURE

CHEMISTRY & AGRICULTURE

Essential Question:  In what ways does chemistry contribute to agriculture?

Learning Objective:  Chemists have developed different ways to help agriculture develop better crops, improve soil quality and fight pests.

SWBAT:

• Investigate the requirements of crops for good growth.
• Understand how pesticides, fungicides and herbicides work and the controversies surrounding their use. 
• Compare and contrast  "organic" products to what consumers consider "GMO" 

 CK-12: AGRICULTURE ASSIGNMENT

HMMM... BE READY TO PARTICIPATE

• Of the two tomatoes that I am holding, which one is "organic"? How can you tell?
• What do you know about "organic food"?
• What does GMO stands for? Who makes GMO food? 
  • How? Is GMO food good for you?
• What chemical process  is the basis for all the oxygen in the atmosphere and the food we eat? What organism is responsible  for that process?
• WHY should we care about all of this? 

PHOTOSYNTHESIS: http://www.biology4kids.com/files/plants_photosynthesis.html (Links to an external site.)

• Can you write down the chemical reaction for PHOTOSYNTHESIS? Go ahead... Give it a try!
• If there is ONE chemical reaction you need to remember is the PHOTOSYNTHESIS REACTION. (Links to an external site.) WHY, YOU ASK?!?! Do you remember your Bio class? Remember ECOLOGY?
  • • • Which organism is at the bottom of the energy pyramid (Links to an external site.)? Why is that?
• Without the chemical process of PHOTOSYNTHESIS (Links to an external site.)  LIFE, as we understand it, will not exits
• Some anaerobic  bacteria (Links to an external site.) will continue to thrive but aerobic organisms will cease.
  • You, your cat, your dog, the cow that provides your yummy hamburger are all aerobic organisms. 
• So, again, WHY should we care about all of this? 
• How can chemistry help our plant friends and the people who provide veggies for us? Can you think of a way chemistry has helped agriculture?

ANSWER THIS:

• WHAT IS THE TERM FOR THE AREA BEFORE THE ARROW?
• WHAT IS THE TERM FOR THE AREA AFTER THE ARROW?
• WHAT DOES THE ARROW MEAN?
• COMPARE AND CONTRAST THE AREA BEFORE THE ARROW TO THE AREA AFTER THE ARROW

GMO's

• Genetic Modified Organisms (GMO's) or Genetic Modified  (GM) or Genetic Engineered (GE) have been a subject of debate for decades. Are they good for you? Are they bad? 
• The debate continues and it is up to the individual consumer to educate themselves and  to make the right choice when going to the grocery.
• Being informed about the pros and cons give you the power to choose what it is best for you and your family.

IS ORGANIC BETTER FOR YOU?

WHAT'S THE DIFFERENCE BETWEEN PESTICIDES, HERBICIDES AND FUNGICIDES?

• Another hot topic are PESTICIDES, HERBICIDES AND FUNGICIDES. Why do you think that is?
• The common sense response from consumers is: "If they kill bugs, pests, fungi... Would it kill me, too?"
• The answer to that will depend on who's paper you are reading. 
• Being informed of the pros and cons, again, gives you power to make the right choice for you and your family.
