- Matter
- Matter is anything that has mass and takes up space; it can be solid, liquid, or gas.
- Physical change
- A physical change alters size, shape, or state without making a new substance, such as melting ice or tearing paper.
- Chemical change
- A chemical change forms one or more new substances, often shown by color change, gas, heat, light, or a new smell.
- Force
- A force is a push or pull that can change an object's motion or shape; forces have strength and direction.
- Speed formula
- Speed equals distance divided by time. A car traveling 100 kilometers in 2 hours has a speed of 50 kilometers per hour.
- Friction
- Friction is a force that opposes motion when surfaces touch; it produces heat and can slow or stop moving objects.
- Electrical conductor
- An electrical conductor lets electric current flow easily, while an insulator resists current; metals are usually good conductors.
- Energy transfer
- Energy can move from one object to another or change form, but it is not created or destroyed in ordinary events.
- Cell
- A cell is the smallest living unit of an organism; some organisms have one cell, while others have many.
- Photosynthesis
- Photosynthesis is how green plants use sunlight, water, and carbon dioxide to make sugar and release oxygen.
- Food chain
- A food chain shows the path of energy from producers to consumers and decomposers; arrows point to the organism that gets energy.
- Producer
- A producer makes its own food using sunlight, water, and carbon dioxide; plants and some algae are producers.
- Adaptation
- An adaptation is a body part or behavior that helps an organism survive in its environment, such as thick fur in cold places.
- Ecosystem
- An ecosystem includes living organisms and nonliving parts, such as water, soil, air, and sunlight, interacting in one area.
- Life cycle
- A life cycle is the series of stages an organism passes through from birth or seed to adulthood and reproduction.
- Inherited trait
- An inherited trait is a characteristic passed from parents to offspring through genes, such as eye color or leaf shape.
- Water cycle
- The water cycle moves water through evaporation, condensation, precipitation, and collection, recycling Earth's water.
- Weathering
- Weathering breaks rocks into smaller pieces without moving them; erosion then carries the pieces away.
- Erosion
- Erosion is the movement of weathered rock, soil, or sand by water, wind, ice, or gravity to a new place.
- Deposition
- Deposition happens when eroded materials settle in a new place, forming layers that may become sedimentary rock.
- Rotation
- Earth's rotation is its spin on its axis, taking about 24 hours and causing day and night.
- Revolution
- Earth's revolution is its orbit around the Sun, taking about 365 days and causing the seasons with axial tilt.
- Moon phases
- Moon phases are the changing shapes of the lit part of the Moon we see as it orbits Earth, repeating about monthly.
- Natural resource
- A natural resource is something from Earth that living things use, such as water, minerals, soil, and forests; some are renewable.
- Engineering design process
- The engineering design process is a cycle of defining a problem, planning, building, testing, improving, and sharing a solution.
- Criteria
- Criteria are the requirements a design must meet to be successful, such as size, cost, safety, or speed.
- Constraints
- Constraints are limits on a design, such as available materials, time, budget, space, or safety rules.
- Prototype
- A prototype is a first working model used to test an idea before making the final product.
- Variable
- A variable is a factor that can change in a test; scientists change one variable and keep others the same.
- Fair test
- A fair test changes only one variable at a time and keeps all other conditions the same so results can be compared.
- Trade-off
- A trade-off is giving up one benefit to gain another when a design cannot meet every goal perfectly.
- Model
- A model is a simple representation used to explain or test something that is too big, small, costly, or dangerous to observe directly.
