Common Core/Next Generation Science Standards Addressed WHST.6‐8.1 - Write arguments to support claims with clear reasons and relevant evidence.(MSLS2‐4) WHST.6‐8.2 - Write informative/explanatory texts to examine a topic and convey ideas, concepts and information through the selection, organization, and analysis of relevant content. (MS‐LS1‐6) SL.8.1 -Engage effectively in a range of collaborative discussions (one‐on‐one, in groups, and teacher‐led) with diverse partners on grade 8 topics, texts, and issues, building on others’ ideas and expressing their own clearly. (MS‐LS2‐2) SL.8.4 - Present claims and findings, emphasizing salient points in a focused, coherent manner with relevant evidence, sound valid reasoning, and well‐chosen details; use appropriate eye contact, adequate volume, and clear pronunciation. (MS‐LS2‐2) SL.8.5 - Include multimedia components and visual displays in presentations to clarify claims and findings and emphasize salient points. (MS‐LS3‐1),(MS‐LS3‐2)
Bell Work Activities! • 1. Define “urban” Agriculture, why is it important? • 2. What “Ag.” industries are important here in N.M.? • 3. What is the difference between Production Agriculture and an Agri-business?
Agriculture industry Agriculture Agribusiness Aquaculture Biotechnology Domestication Farming Forestry Inventions Natural Resources Terms
Ornamental Horticulture Suburban Farming Technology Terms (continued)
Student Learning Objectives • Define agriculture and the agriculture industry • Identify important historical developments in agriculture • Explain major technological developments in agriculture
Objective One Define Agriculture and The Agriculture Industry
What is Agriculture? • Agriculture is the science of growing crops and raising animals to meet the needs of humans
What is an Ag Industry? • Involves all activities involved with providing people with food, clothing, and shelter • Includes farm operations, and • Nonfarm operations • Largest industry in America
What are Farming / Ranching Operations? • Uses land and other resources to grow crops and raise animals. • Includes - conventional farming, suburban farming, aquaculture, and forestry.
Conventional Farming • Larger acreage of land growing grain, vegetables, fruit and fiber crops. ( Which category is Chili?) • Producing large numbers of animals like swine, beef, dairy cattle, sheep and poultry.
Suburban Farming • Normally involves smaller areas of land. • Normally found in residential or business locations. • Typical products would include vegetable crops and small animals.
Aquaculture • “Farming the Water” • Involves raising fish or similar aquatic animals • Also includes producing aquatic plants like water cress or water chestnuts
Forestry • Involves the production and use of trees
What are Nonfarm Operations? • Normally referred to as Agribusiness • Agribusiness is nonfarm work in areas such as ag supplies, services, marketing, and product processing
Agriculture Also Makes the Lives of People Better • Ornamental Horticulture produces flowers and plants for their beauty • Natural Resources involve working with things found in nature like soil, water, and air
Objective Two Identify Important Historical Developments in Agriculture
Two Important Groups of People That Affected Early Agriculture • Native Americans • Colonists
Native Americans • Includes Indians, Hawaiians, and Eskimos • Hunting and gathering met their food and fiber needs • Indians first began simple farming • By 1000 AD, corn is being grown in large plots
Colonists • Learned many successful ag practices from Native Americans • Credited with early domestication of animals, which is the taming, confinement, and breeding of animals for human use
Objective Three • Explain major technological developments in agriculture
What is Technology? • Technology is the application of knowledge to practical use • Uses inventions (new devices, products, or ways of doing work) for easier work and better living
