Placement SAE is A Supervised Agricultural Experience that requires the student to work for someone else in an agriculture related job. The work may or may not be paid. (working on a farm or a ranch, in a farm supply store or a food testing laboratory or in an agriculturally related non-profit organization.) Exploratory SAE is A Supervised Agricultural Experience designed to increase student agricultural career awareness through exploration activities. Exploration activities may include observing, interviewing, or assisting an individual in an agriculture related profession, participating in a field day or event, or giving a classroom demonstration. Research SAE is A Supervised Agricultural Experience designed for students to use the scientific method to analyze a research question or test a hypothesis. Research SAEs may be experimental projects (comparing plant growth using different growing methods), as well as non-experimental ones (developing a marketing plan or ad campaign for an agriculture commodity). (raising and selling animals or crops, building and selling agricultural equipment, and buying and reselling feed, seed or fertilizer,)
Ag Education includes three parts: Classroom instruction, SAE, and FFA
Soil is made up of air, water, minerals, and organic matter. The air and water keep the roots healthy and they provide water to the plant. The organic matter breaks down to provide nutrients to the growing plant. The minerals are just broken up pieces of rock that give the roots a place to live and grow. These minerals are different sizes and called Sand, Silt, and Clay. Draw a picture of the different sizes of these particles.
