The Nature of: Explain how the science of agriculture helped develop civilization; o Identify and define the various areas of science and agriscience; and o Discuss advancements made through agriscience. o What was the first science? › Agriculture! › Science is knowledge obtained through a systematic study of naturally occurring phenomena The first systematic study by humans was obtaining food, shelter, and clothing How has the science of agriculture helped develop society? › Time was a large factor in developing society How was food obtained in the beginning of human history? › Hunter/Gatherer › People moved with the food Did they have time to build a home? Agriculture began about 10,000 years ago › Where? › Fertile crescent People began growing their own food What did that do to their ‘time’? › No wandering › Build a more permanent shelter › Build villages and communities Science grew as humans worked to develop better ways to produce food › Trial and error If they can produce food more efficiently how does that affect their time? › Surplus food was traded › Building, engineering, literature, and art skills could be developed Science further grew as farming implements needed to be invented and improved Tools made growing and raising food more efficient › Time? › More of it was spent inventing tools and making life easier It is believed that writing and counting developed from agriculture › Surplus, storage bins, trade, sale, and eventually taxation › Containers had to be marked to indicate: Ownership, contents, and the amount This made the way for written language to be developed Two broad areas › Basic Research Why or how processes occur in plants and animals › Applied Research uses discoveries made in basic research to help in practical ways Mathematics Physical Science Life Science Social Science Most areas overlap Arithmetic › Study of numbers and methods of calculating Geometry › Practical area of math › Mathematical relationships (lines, angles, etc. Several other areas › logic, algebra, calculus, probability, statistics Earth Science › Study of the environment in which plants and animals grow Geology › Study of earth’s composition, structure, history (soil science is a big part of this) Meteorology › study of earth’s atmosphere Other areas include: hydrology, oceanography, astronomy Botany › study of plants Zoology › study of animals Deals with human society, sometimes called behavioral science Includes anthropology, psychology, sociology, education Study of the makeup of material (matter) › Matter is anything that takes up spaces or has mass Study of the physical nature of objects › heat, light, electricity, mechanics made up of several areas of science similarities with areas of occupations many of these areas overlap Agronomy Horticulture Forestry Entomology Mechanical Technology Animal Science Poultry Science Aquaculture Environmental Science Study of plants and how they relate to soil Purpose: › Improve crop production and conserve natural resources Growing crops for food, comfort, beauty › Ornamental Horticulture › Olericulture › Pomology Growing and using forests Part of Zoology Study of insects and related small animals Production of animals for food Raising chickens and other related fowl Water Farming Wisely using and protecting the things around us Use of machines and equipment to do work Discoveries have been made throughout our history to improve our lives › Lets list a few of the recent ones Genetically engineered plants We have been doing this for as long as agriculture has been around through selective breeding Tomato Calgene developed a tomato that resists rot Corn BT corn Round-Up Ready Many including: corn, sugar beets, cotton, alfalfa, canola, soybeans and others Alternative Fuels › Ethanol Henry Ford’s Model T ran off of ethanol What is used to produce ethanol? Corn Will that affect our food supply? › Bio-Diesel › Is making your own fuel safe? What could happen? Pest control › Synthetic controls for fire ants in the south Higher ratio of nonproductive drone ants to worker ants › Synthetic controls for fruit tree insects Pheromones released will attract the male insects so they never find a female
