Grade 8 S.A.I.L Science 81-84: Course Overview
Course Number: SCM.SAIL81 - SCM.SAIL84
This is the third year of a standards-based, coordinated, three-year integrated middle school science program. This course emphasizes concept and skill development and contains a balance of physical, biological, earth/space, and environmental science topics. Each unit focuses on applying the Scientific Process in one major scientific concept, which is developed through a thematic approach. The major concepts include: Biochemical Processes; Particles--The Structure of Matter; Machines, Work, and Energy; Oceans and Climates; Sound; Light; and Human Body and Health Topics, including the Nervous and Reproductive Systems, Heredity, Drug Awareness, and Health-related careers. Students construct their own understanding through an inquiry-based approach. Activities include open-ended investigations, small-group discussions, exploratory writing and reflective reading tasks, and long-range projects. Assessment activities are varied and teach as well as evaluate comprehension and performance.

Enduring Understandings - important ideas that students should carry with them years beyond the instruction received this year.
- Scientists investigate the world around them and communicate to others through the scientific process.
- The scientific process is the basis of an integrated approach to understanding our world. (topic/problem, testable question, hypothesis, procedure)
- Scientists use a plan to carry out an investigation (variables, control, data, observations, investigations).
- Scientists select, appropriate tools to collect, organize, and record data using the metric system in tables, charts, and graphs. Scientists analyze data for reliability and validity to form a conclusion. Scientists analyze data to infer past and predict future events.
- Scientists ask questions based on their investigations and these questions can lead to new investigations.
- Scientists communicate the results of their investigations in many formats and appropriate ways.
- All matter exists in specific states (e.g. solid, liquid, gas, plasma) and has characteristic chemical and physical properties. All matter has characteristic chemical and physical properties which can be described, and a variety of quantities can be compared (Conservation of Matter).
- Matter can be separated using procedures based on characteristic properties.
- Chemical reactions are processes in which atoms are rearranged into different combinations of molecules. After a chemical reaction, a new set of chemical properties can be observed.
- Elements are pure substances that can not be broken down by routine laboratory procedures; compounds are pure substances that are formed by the combination of elements in definite proportions. All forms of matter are composed of one or more of the elements
- The Periodic Table of Elements is both a tool and an organized arrangement of the elements that demonstrates the underlying atomic structure of the elements.
- There are measurable properties of kinetic and potential energy. Energy cannot be created nor destroyed.
- Different simple machines produce different mechanical advantages.
- There are measurable changes as energy is transferred or transformed.
- The world population uses both renewable and nonrenewable resources.
- The world is affected by the interrelationship of science and technology.
- New technology continually impacts human activity.
- Experiments must be controlled and have reproducible results.
- Scientists identify, determine, compare, and control variables. Scientists must be objective and bias free when examining their work. Scientists communicate their results using various methods.
- Scientists use models to predict change.
- Safety is a primary concern with all laboratory techniques.
Essential Questions - most important “big picture” questions students should be able to answer after completing learning activities.
What is a testable question that leads to a proposed hypothesis? How is a testable question developed?
How do scientists design a plan for investigating a testable questions? How is an investigation organized?
