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

Students study what matter is made of and how it changes. They learn why substances behave differently when mixed, heated, or broken apart at the atomic level.

Students study how energy moves and changes form, from heat and light to motion and stored energy in objects. They explain why a moving ball, a warm cup, or a stretched rubber band each holds energy in a different way.

Students study how living things are built and how they work, from the molecules inside cells all the way up to organs and body systems.

Students study how living things in an ecosystem depend on each other and on their environment. They trace how energy moves through food webs and explore what happens when ecosystems are disrupted by natural events or human activity.

Students study how traits pass from parents to offspring and why siblings can look different from each other. They learn how genes and reproduction explain both family resemblance and variation.

Students learn to spot a real-world problem, brainstorm solutions, build a rough model, and test whether it works. The goal is to improve the design based on what the tests show.

Matter is made of tiny building blocks called atoms, and those atoms combine in different ways to form every substance around us. Students study how the type and arrangement of atoms determines what a material actually is.

Students test the physical properties of a mixture's parts, like color, texture, or melting point, before and after a chemical reaction to see whether those parts have changed into something new.

Students use diagrams or models to show how heating, cooling, or squeezing a substance changes how its particles move and how close together they are. That explains why matter changes state or behaves differently under pressure.

In a chemical reaction, no atoms appear or disappear. Students use numbers and arithmetic to show that every atom on the starting side of a reaction is still there on the finished side.

Students mix substances together and observe whether a chemical reaction happens. The experiment shows whether that reaction gives off energy (like heat or light) or absorbs it.

Students model how the body breaks down food through chemical reactions to build new molecules for growth and release energy. It explains what happens inside cells after a meal.

Students learn the parts of a cell and what each one does. They build a model showing how structures like the nucleus, mitochondria, and cell membrane work together to keep the cell alive.

Students compare how single-celled organisms like bacteria and multi-celled organisms like plants or animals are built differently inside, and explain how those structures help each organism get food, take in water, and get rid of waste.

Students map out how the human body is organized, from cells to tissues to organs to organ systems, and explain how those systems work together to keep the body running.

Students look at data to figure out what shapes how living things grow, comparing inherited traits like breed or species against outside conditions like food supply and space.

Sensory receptors pick up signals from the world around us, and the body uses those signals to trigger a response. Students explain how a smell, sound, or touch can cause an instant reaction or shape behavior over time.

Students use Punnett squares and diagrams to show why two parents produce offspring with a mix of traits, while a single parent reproducing on its own passes down an exact genetic copy.

Students learn how living things turn sunlight, food, and air into usable energy. They build a model showing where that energy comes from, where it goes, and how the same atoms cycle through plants and animals again and again.

Students draw or diagram how carbon and oxygen move through living things, soil, water, and air, and how energy flows from the sun through plants, animals, and back into the environment.

Chromosomes carry thousands of genes, and each gene acts as a set of instructions for making a protein. Those proteins shape the traits a person actually has, from eye color to how the body grows.

A mutation is a change in a gene that can shake up how the body works. Students explain how some mutations cause serious problems, others give an advantage, and some make no noticeable difference at all.

Students use a Punnett square to predict the chances a child inherits a dominant or recessive trait from each parent. They show the results as ratios, like 3 to 1, to describe how often a trait is likely to appear.

Students pick a real medical problem, like a missing limb or a failing organ, then sketch a solution that fits the rules, the budget, and the science that applies.
