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

Students identify a question or problem that can actually be tested or built, not just looked up. This is the starting point for most science and engineering work in middle school.

Students build or draw models (diagrams, simulations, physical prototypes) to show how a natural event or engineered system works, then use those models to explain patterns or test ideas.

Students design and run experiments to collect real data, then use that data to check whether their ideas hold up.

Students look at data from experiments or investigations and find patterns that explain what happened. The goal is to pull meaning from the numbers or observations, not just report them.

Students use math and calculations to back up their science thinking. That might mean running numbers on data, spotting patterns in a graph, or checking whether a result makes sense.

Students take what they observed or measured and write an explanation that connects the evidence to a scientific idea. The explanation has to hold up, meaning the data must actually support the claim.

Students look at two or more scientific explanations or design solutions, weigh the evidence behind each, and make a case for which one holds up better.

Students read scientific sources, judge whether the information holds up, and explain what they found in writing, discussion, or a presentation.

Students learn what matter is made of at the atomic level and use that knowledge to explain everyday physical events, like why ice melts or why some materials conduct heat better than others.

Students study why things speed up, slow down, or stay still. They learn Newton's laws to explain pushes, pulls, and collisions, and see how energy and momentum stay balanced across a system.

Students track how energy changes form and moves from one object to another, and confirm that the total amount of energy in a system stays the same before and after a transfer.

Students study how waves, like sound and light, carry energy from place to place and how that same movement is used to send signals, pictures, and data across distances.

Students examine how living things are built and how they work, starting with cells and zooming out to tissues, organs, and whole body systems.

Students trace how energy from the sun and matter like water and carbon move through living things in an ecosystem. They also study how organisms compete, cooperate, and depend on each other to survive.

Students explore how traits like eye color or height pass from parents to offspring, and why siblings can look different even when they share the same parents.

Students compare living things across species to spot both shared traits and key differences, then explore how populations change over generations through natural selection and other forces.

Students study where Earth sits in the solar system and how the planets move in predictable patterns. They also look at how Earth itself formed and changed over billions of years.

Students study how Earth's major systems, the land, water, air, and living things, each affect the others. They look at what happens when one system changes and how that change ripples through the rest.

Students examine how things people do, like burning fuel or building cities, change land, water, and air. They also look at how earthquakes, floods, and other natural events affect where and how people live.

Students identify a real problem, brainstorm and test possible fixes, then improve their design based on what the tests reveal.

Engineering and society shape each other in both directions. Students examine how inventions change daily life and how social needs push engineers to solve new problems.
