Mixtures of matter can be separated regardless of how they were created; all weight and mass of the mixture are the same as the sum of weight and mass of its parts
Life Science
All organisms have structures and systems with separate functions
Human body systems have basic structures, functions, and needs
Earth Systems Science
Earth and sun provide a diversity of renewable and nonrenewable resources
Earth’s surface changes constantly through a variety of processes and forces
Weather conditions change because of the uneven heating of Earth’s surface by the Sun’s energy. Weather changes are measured by differences in temperature, air pressure, wind and water in the atmosphere and type of precipitation
Fourth Grade
Physical Science
Energy comes in many forms such as light, heat, sound, magnetic, chemical, and electrical
Life Science
All living things share similar characteristics, but they also have differences that can be described and classified
Comparing fossils to each other or to living organisms reveals features of prehistoric environments and provides information about organisms today
There is interaction and interdependence between and among living and nonliving components of systems
Earth Systems Science
Earth is part of the solar system, which includes the Sun, Moon, and other bodies that orbit the Sun in predictable patterns that lead to observable paths of objects in the sky as seen from Earth
Third Grade
Physical Science
Matter exists in different states such as solids, liquids, and gases and can change from one state to another by heating and cooling
Life Science
The duration and timing of life cycle events such as reproduction and longevity vary across organisms and species
Earth Systems Science
Earth’s materials can be broken down and/or combined into different materials such as rocks, minerals, rock cycle, formation of soil, and sand – some of which are usable resources for human activity
Second Grade
Physical Science
Changes in speed or direction of motion are caused by forces such as pushes and pulls.
Life Science
Organisms depend on their habitat’s nonliving parts to satisfy their needs
Each plant or animal has different structures or behaviors that serve different functions
Earth Systems Science
Weather and the changing seasons impact the environment and organisms such as humans, plants, and other animals
First Grade
Physical Science
Solids and liquids have unique properties that distinguish them
Life Science
Offspring have characteristics that are similar to but not exactly like their parents’ characteristics
An organism is a living thing that has physical characteristics to help it survive
Earth Systems Science
Earth’s materials can be compared and classified based on their properties
Kindergarten
Physical Science
Objects can move in a variety of ways that can be described by speed and direction
Objects can be sorted by physical properties, which can be observed and measured
Life Science
Organisms can be described and sorted by their physical characteristics
