What does a student learn in StateGeorgia,GradeGrade 7,SubjectScience?

Students learn to research and compare living things, from bacteria to plants to animals, using scientific evidence to explain how organisms are alike and different.

Students sort living things into groups based on shared traits, then explain why each organism belongs where it does. The focus is on building a system that holds up when questioned.

Students learn how scientists sorted living things into groups over time, and why the system eventually split into six kingdoms. The focus is on how new evidence changed older classification models.

Cells group together to form tissues, tissues form organs, and organs work together in systems that keep the body running. Students learn how those layers connect, from the smallest cell structure up to full organ systems like digestion or circulation.

Students draw or diagram a cell and explain what each part does, from the nucleus directing the cell to the mitochondria producing energy, showing how the parts work together to keep the cell fed, growing, and clean.

Cells group together into tissues, tissues form organs, and organs work together as systems that keep a whole organism alive. Students build a model that shows how each level connects to the next.

Students build a case for how body systems work together to keep a person alive. For example, the lungs pull in oxygen while the heart pumps it through the blood, and the kidneys filter out what the body no longer needs.

Students learn how living things pass traits to their offspring, whether through two parents sharing genetic information or one parent copying itself. They look at real examples to explain why offspring end up looking similar to, but not always identical to, their parents.

Genes are sections of DNA stored on chromosomes, and they carry the instructions that determine a specific trait, like eye color or height. Students explain how those instructions pass from parent to offspring using real scientific evidence.

Students use diagrams or models to show why offspring from asexual reproduction are genetic copies of one parent, while offspring from sexual reproduction can look different from either parent.

Selective breeding is when humans choose which plants or animals reproduce together to encourage specific traits. Students explain how farmers, breeders, and scientists have used this practice to shape traits like crop size, disease resistance, or animal behavior over generations.

Students study how living things depend on each other and their surroundings to survive. They look at what happens when one part of an ecosystem changes and how that ripples through the rest.

Students study how living things in an ecosystem depend on each other and on nonliving factors like water, sunlight, and soil. They explain why those relationships follow predictable patterns across different environments.

Students build a diagram or model showing how energy moves through a food web and how matter like water, carbon, or nutrients cycles between living things and their surroundings.

Resource changes, disease, weather shifts, and human activity all affect living things. Students study real data to explain how those pressures change individual animals, whole populations, and the broader ecosystems they live in.

Students compare Earth's major biomes, from tropical rain forests and deserts to tundra and open ocean, by gathering information from multiple sources. The goal is explaining how climate, plants, and animals differ from one place to the next.

Students learn why living things look and behave the way they do by studying how useful traits get passed from parents to offspring across many generations. Over time, those inherited traits can shift a whole species.

Students use graphs or data tables to show how a useful trait, like camouflage or disease resistance, spreads through a population over generations when organisms with that trait survive and reproduce more often.

Genetic variation means individuals in a species differ slightly from one another. Students explain how those differences, combined with environmental pressures like food scarcity or predators, make some individuals more likely to survive and have offspring.

Fossils leave a record of which creatures lived, changed, and died out over time. Students read that record to find patterns and connect ancient organisms to the living things we recognize today.
