Competencies and Learning Targets for Grade 7 in 2017-2018


Science

FORCES AND INTERACTIONS

▪ Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

MATTER AND ENERGY IN ORGANISMS AND ECOSYSTEMS

▪ Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

▪ Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

GROWTH, DEVELOPMENT, AND REPRODUCTION OF ORGANISMS

▪ Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

▪ Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

▪ Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

▪ Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms.

▪ Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

NATURAL SELECTION AND ADAPTATIONS

▪ Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.

▪ Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.

▪ Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships.

▪ Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.

▪ Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

EARTH'S SYSTEMS

▪ Construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes.

▪ Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity.

WEATHER AND CLIMATE

▪ Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

▪ Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.

▪ Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

HUMAN IMPACTS

▪ Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.
