GRADE SEVEN SCIENCE - NEXT GENERATION SCIENCE STANDARDS
The Science Curriculum taught at Daniel Wright School reflects the recommendations of the Next Generation Science Standards.
The Daniel Wright Junior High School Science teachers rewrote the science curriculum during the 2014-2015 school year using the Next Generation Science Standards. This is the first year (2015-2016) the new units are being taught. There may be some variation between the intended curriculum, what is described here, and the implemented curriculum. Revisions may be made to the curriculum units as the unit is being taught.
To better understand the structure of the Science curriculum for the middle school (6-8) students, an explanation of four major disciplines within the field of science can be found by accessing the links below.
Science Units taught in Grade Seven include:
In this unit, students will 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. They will 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. 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. They will construct a scientific explanation on evidence for how environmental and genetic factors influence the growth of organisms.
In this unit, students will develop an understanding of the structure and function of cells. Students will conduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and types of cells. Students will develop and use a model to describe the function of a cell as a whole and ways the parts of the cell contribute to the function. They will develop an argument supported by evidence for how the body is a system of interacting subsystems composed of a group of cells. They will construct a scientific explanation on evidence for how environmental and genetic factors influence the growth of organisms.
In this unit, students will develop an understanding of matter and energy cycles between living and non-living factors. Students will understand how photosynthesis and respiration within organisms cycle materials through an ecosystem. Students will develop models that show how food is rearranged into different molecules that support growth and release energy. Students will collect data and interpret this data to understand the relationships within living and nonliving components of an ecosystem.
Earth Within the Universe
In this unit, students will develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. Students will use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave. Students will integrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information. Students will develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons They will also develop and use a model to describe the role of gravity in the motion within galaxies and the solar system Students will be able to construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interaction.
Scientific Inquiry Method is integrated throughout the Science Curriculum.
The Science Performance Expectations for Grade Seven have been recommended by the Next Generation Science Standards, a collaborative group of over 20 states, including Illinois.
