1. August 2008 Using Applied Science and Technology By Howard Henderson Chapter 2 Agriscience/Technology GA Ag Ed Curriculum Office To accompany the Georgia Agriculture Education Curriculum Lesson 02471-2 July 2002 From foukeffa.org

2. August 2008 DEFINITION OF AGRISCIENCE It is the use of science in producing food, fiber and shelter Applied science answers the questions “What should I do?” “What chemical to use?” Basic science answers the question “Why does it do what it does?” ex. Why chemical works

3. August 2008 TECHNOLOGY Practical use of science- usually increases food production Development of BST in dairy to increase the amount of milk one cow will produce *ADVANTAGE – Less cows needed *DISADVANTAGE – Less dairy farmers needed

4. August 2008 LEADERSHIP AND TECHNOLOGY Agriscientists and government officials often make decisions about what will be available Example would be in the US Monsanto developed a soybean that produces sterile seed; they decided NOT to put in on the market

5. August 2008 FOUR AREAS OF SCIENCE Mathematics- weight to buy and sell a product; land surveying Physical science- nonliving matter; earth science/chemistry/phy sics; example accurate weather/fertilizer/loadi ng ramps

6. August 2008 FOUR AREAS CONT. Life science- study of living things includes botany and zoology: ways to make plants and animals grow better Social science- behavioral science: why people respond as they do to food

7. August 2008 AGRONOMY Deals with the study of plants and how they relate to the soil Purpose is to improve crop production and conserve natural resources

8. August 2008 HORTICULTURE Science of growing fruits, nuts, and vegetables Also includes flowers and ornamental shrubs and vines

9. August 2008 FORESTRY Science of growing and using forests Two types of forests: 1. cultured- trees are planted and cared for 2. native- trees that grow wild; usually a mixture of types

10. August 2008 ENTOMOLOGY Branch of zoology that deals with insects and related small animals Includes: -beneficial insects: honeybee -harmful insects: corn borers

11. August 2008 ANIMAL SCIENCE Area of agriscience dealing with the production of animals for food Animals used for meat include cattle, hogs, sheep, goats, bison, emus, and llamas

12. August 2008 POULTRY SCIENCE Area dealing with raising chickens and related fowl (birds) Most important: chickens Others include: turkeys, ducks, geese, pheasants, quail, and guinea

13. August 2008 AQUACULTURE Is the science of water farming Deals with both aquatic plants and animals Examples of plants: water chestnuts and water cress Examples of animals: trout and alligators

14. August 2008 ENVIRONMENTAL SCIENCE Involves ways of wisely using and protecting the things around us Emphasis in environmental science include the air, soil, water, wildlife, native plants and minerals

15. August 2008 MECHANICAL TECHNOLOGY Involves the use of machines and equipment to do work Examples are developing: tractors, greenhouses, ponds, harvesting equipment, etc.

16. August 2008 SCIENTIFIC METHOD Five important steps Step one: Identify the problem -example: too much backfat in local pigs used for slaughter Step two: Get information -example: collect data from slaughter houses in area

17. August 2008 SCIENTIFIC METHOD CONT. Step three: Suggest an answer -example: use a superior boar on area sow herds Step four: Experiment -example: feed out offspring and compare cut out data Step five: Form conclusions -example: need to use new genetics in our area

18. August 2008 RESEARCH Agriscience research is carried out by land- grant universities, agricultural agencies, agribusinesses and other groups A few farms do research

19. August 2008 NEW AREAS OF AGRISCIENCE Biotechnology Genetic engineering Remote sensing Laser technology Computational science Radiation

20. August 2008 BIOTECHNOLOGY Examples of biotechnology: –Developing vaccines –Products that will cause livestock to produce more meat on less food –Developing bacteria that will consume wastes

21. August 2008 GENETIC ENGINEERING Develop crops that are insect resistant Develop a tomato that is rot resistant Develop a crop plant that kills the weeds around them

22. August 2008 REMOTE SENSING Involves gathering and recording data from a great distance Weather information Resource location Crop pests Protecting natural resources

23. August 2008 LASER TECHNOLOGY A device that produces a special kind of light Land forming Monitoring processes Scanning- supermarkets

24. August 2008 COMPUTATIONAL SCIENCE Using computers to solve problems in agriscience Designing facilities Developing products Modeling natural resources

25. August 2008 RADIATION Use of radiation Preventing spoilage of food by killing bacteria that may be on or in food product Keeping insects out of stored food

26. August 2008 ISSUES ASSOCIATED WITH AGRITECHNOLOGY Food safety Pollution Conservation of resources Human rights: Example- food products should not be imported from a nation where pesticides are being used improperly
