Cells & organisms
How do cells help living things survive? Explore structures, functions, and the needs of organisms.
Start with an observation →Science begins with curiosity.
Learn how scientists investigate questions about living things, matter, energy, and our planet. Explore one topic at a time, then use evidence to explain what you observe.
Choose a topic that interests you. These learning themes are introductory pathways, not a claim of exact sequence in every New York classroom.
How do cells help living things survive? Explore structures, functions, and the needs of organisms.
Start with an observation →Compare solids, liquids, and gases. Describe measurable properties and recognize how matter can change.
Try a matter question →Notice heating, cooling, light, and motion. Ask where energy moves and what evidence reveals a change.
Practice using evidence →Explore water, weathering, landforms, and the interactions that shape local environments.
Explore a science question →A good investigation starts with a testable question. Clear observations and consistent methods make your results more useful.
What could you change, observe, or measure? Be specific enough to compare outcomes.
Change one factor when possible and keep important conditions consistent.
Describe what happened, connect it to your claim, and note any uncertainties.
A student wants to know whether water temperature affects how quickly sugar dissolves. They use equal amounts of sugar and water, the same cups, and the same stirring procedure.
The student changes the temperature of the water to compare two conditions.
The student records how long the sugar takes to dissolve in each cup.
The sugar amount, water volume, cup type, and stirring procedure stay the same.
What is the variable the student deliberately changes?
Choose an answer to check your thinking.
This is a conceptual investigation. For hands-on activities involving warm water, ask an adult to supervise.
Ask: What changes when sunlight moves across a room? What stays the same?
Encourage students to describe what they observe before explaining why it happens.
Try: What did you notice that supports your explanation?
