SCIENCE

Middle School Standards

The middle school student should understand that information collected from scientific investigations can help explain phenomena and can usually lead them to observe further. They should do more logical reasoning, collecting relevant evidence, and apply imagination in devising hypotheses and explanations to problems. Students will describe human nutritional needs, local food production and distribution technologies and the complex interactions of these technologies with economics, health and nutrition, resource depletion, and environmental impact. They will also describe matter as composed of small particles and identify some of the properties; describe complex events by applying simple laws of motion; and, relate human impact to local and regional environments.
