Grade Level Expectations
8.1.2: Calculate the average speed of an object and distinguish between instantaneous speed and average speed of an object.
8.1.3: Create and interpret distance-time graphs for objects moving at constant and nonconstant speeds.
8.1.5: Investigate and demonstrate how unbalanced forces cause acceleration (change in speed and/or direction of an object’s motion).
8.1.6: Assess in writing the relationship between an object’s mass and its inertia when at rest and in motion.
8.1.7: Express mathematically how the mass of an object and the force acting on it affect its acceleration.
8.1.8: Design and conduct an experiment to determine how gravity and friction (air resistance) affect a falling object.
8.2.1: Relate the continued existence of any species to its successful reproduction and explain in writing the factors that contribute to successful reproduction.
8.2.2: Describe the structure, location and function of chromosomes, genes and DNA and how they relate to each other in the living cell.
8.2.3: Illustrate and chart the purpose, cell type (somatic and germ) and resulting chromosome count during cell division in mitosis and meiosis.
8.2.7: Demonstrate the relationship of corresponding genes on pairs of chromosomes to traits inherited by offspring.
8.3.1: Describe in writing how gravitational attraction and the inertia of objects in the solar system keep them on a predictable elliptical pathway.
8.3.2: Distinguish between rotation of Earth on its axis and its elliptical revolution around the sun.
8.3.3: Use models to explain how Earth’s revolution around the sun affects changes in daylight hours and seasonal temperatures.
8.3.6: Use a model to demonstrate the phases of the moon relative to the position of the sun, Earth and moon.
8.3.7: Develop a model or illustration to show the relative positions of the earth, sun and moon during a lunar and solar eclipse and explain how those positions influence the view from Earth.
8.3.8: Describe factors affecting tidal changes and analyze tidal change data for Long Island Sound.
