Field Trips
Farm animals and humans have similar necessities of life to live and grow. Humans and animals both require food, water, and shelter. However, these life necessities are fulfilled in different ways. Humans need clean or purified water. Animals can drink from streams, ponds, and other natural water sources and generally be unaffected by microorganisms that make humans sick. Both animals and humans require healthy food for their diet. Most farm animals thrive on feed that humans cannot digest. For example, cows, goats, and sheep have a multi-compartment stomach which allows them to break down and use the energy and nutrients found in grass and hay. These farm animals then convert their energy into food humans can eat, such as meat and milk. Animal and humans both need shelter from harsh elements—heat during cold weather and cool air during extreme heat. Humans regulate body temperature with their physical environment. We generally live in heated houses to protect ourselves from the cold and use blankets and sweaters to keep warm. Animals have natural defenses. Thick hair or wool on livestock provides insulation from cold temperatures. In some climates, farmers provide enclosed barns or covered areas for warmth in the cold and shade in the heat.
