California Grade 7 Science Online Center

California tests science in grades 5 and 8, not in grade 7, so seventh grade is the year to build the ideas the California Science Test (CAST) will ask about later. Practice tests, skill quizzes, flashcards, and every California science standard for this grade, free.

LS Life Sciences

  • MS-LS1-6Organism Needs, Structures, and Life CyclesConstruct 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
  • MS-LS1-7Cells, Body Systems, and GeneticsDevelop 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
  • MS-LS2-1Organism Needs, Structures, and Life CyclesAnalyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem
  • MS-LS2-3Ecosystems, Food Webs, and Matter FlowDevelop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem
  • MS-LS2-4Ecosystems, Food Webs, and Matter FlowConstruct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations
  • MS-LS2-2Organism Needs, Structures, and Life CyclesConstruct an explanation that predicts patterns of interactions among organisms across multiple ecosystems
  • MS-LS2-5Competing Solutions Maintaining Biodiversity Ecosystem Services Coral ReefEvaluate competing design solutions for maintaining biodiversity and ecosystem services

  • MS-ESS3-1Natural Resources and Human ImpactsConstruct 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
  • MS-ESS3-2Data Natural Hazards Forecast Future Catastrophic Events InformAnalyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects

PS Physical Sciences

  • MS-PS1-2Material Properties and UsesAnalyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred
  • MS-PS1-5Particles, Atoms, Elements, and CompoundsDevelop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
  • MS-PS1-6Chemical and Physical ChangesUndertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes

ETS Engineering, Technology, and Applications of Science

  • MS-ETS1-1Engineering Design and Solution EvaluationDefine the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions
  • MS-ETS1-2Engineering Design and Solution EvaluationEvaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem
  • MS-ETS1-3Engineering Design and Solution EvaluationAnalyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success
  • MS-ETS1-4Engineering Design and Solution EvaluationDevelop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved

California Grade 7 Science FAQ

Does California test science in grade 7?

No. California gives the California Science Test (CAST) in grades 5 and 8, so grade 7 students do not sit a state science test this year. California also gives once in high school. The standards on this page are still the ones grade 7 teachers teach, and they are what the next science test builds on.

Which standards does grade 7 science in California follow?

California follows the Next Generation Science Standards for California Public Schools, K-12, published by the California Department of Education. All 22 of this grade's standards are listed further down the page with their official codes.

How long are the practice tests?

Each of the six practice tests has 40 questions and a 70-minute timer. The timer auto-submits at zero and you get your score, a breakdown by science area, and a written explanation for every question.

Is any of this free?

Yes, every practice test, quiz, and flashcard set on this page is free and needs no login. Your progress is saved in your own browser and nowhere else.

What is the fastest way to use this page?

Take practice test 1 cold. Look at the topic breakdown, pick the weakest science area, and do that skill quiz. Then read the quick review for that area and come back for practice test 2.
