Earth's History

ES.12. Give examples of how the surface of the earth changes due to slow processes such as erosion and weathering, and rapid processes such as landslides, volcanic eruptions, and earthquakes.

Rocks and Their Properties

ES.1. Give a simple explanation of what a mineral is and some examples, e.g., quartz, mica.
ES.3. Identify the three categories of rocks (metamorphic, igneous, and sedimentary) based on how they are formed, and explain the natural and physical processes that create these rocks.


ES.5. Recognize and discuss the different properties of soil, including color, texture (size of particles), the ability to retain water, and the ability to support the growth of plants.

The Earth in the Solar System

ES.13. Recognize that the earth is part of a system called the 'solar system' that includes the sun (a star), planets, and many moons. The earth is the third planet from the sun in our solar system.
ES.14. Recognize that the earth revolves around (orbits) the sun in a year's time and that the earth rotates on its axis once approximately every 24 hours. Make connections between the rotation of the earth and day/night, and the apparent movement of the sun, moon, and stars across the sky.
ES.15. Describe the changes that occur in the observable shape of the moon over the course of a month.

The Water Cycle

ES.10. Describe how water on earth cycles in different forms and in different locations, including underground and in the atmosphere.
ES.11. Give examples of how the cycling of water, both in and out of the atmosphere, has an effect on climate.


ES.6. Explain how air temperature, moisture, wind speed and direction, and precipitation make up the weather in a particular place and time.
ES.7. Distinguish among the various forms of precipitation (rain, snow, sleet, and hail), making connections to the weather in a particular place and time.
ES.9. Differentiate between weather and climate.


Adaptations of Living Things

LS.7. Give examples of how changes in the environment (drought, cold) have caused some plants and animals to die or move to new locations (migration).
LS.8. Describe how organisms meet some of their needs in an environment by using behaviors (patterns of activities) in response to information (stimuli) received from the environment. Recognize that some animal behaviors are instinctive (e.g., turtles burying their eggs), and others are learned (e.g., humans building fires for warmth, chimpanzees learning how to use tools).
LS.9. Recognize plant behaviors, such as the way seedlings' stems grow toward light and their roots grow downward in response to gravity. Recognize that many plants and animals can survive harsh environments because of seasonal behaviors, e.g., in winter, some trees shed leaves, some animals hibernate, and other animals migrate.

Characteristics of Plants and Animals

LS.1. Classify plants and animals according to the physical characteristics that they share.

Energy and Living Things

LS.11. Describe how energy derived from the sun is used by plants to produce sugars (photosynthesis) and is transferred within a food chain from producers (plants) to consumers to decomposers.

Structures and Functions

LS.2. Identify the structures in plants (leaves, roots, flowers, stem, bark, wood) that are responsible for food production, support, water transport, reproduction, growth, and protection.
LS.3. Recognize that plants and animals go through predictable life cycles that include birth, growth, development, reproduction, and death.
LS.4. Describe the major stages that characterize the life cycle of the frog and butterfly as they go through metamorphosis.


Electrical Energy

PS.6. Recognize that electricity in circuits requires a complete loop through which an electrical current can pass, and that electricity can produce light, heat, and sound.
PS.8. Explain how electromagnets can be made, and give examples of how they can be used.

Forms of Energy

PS.4. Identify the basic forms of energy (light, sound, heat, electrical, and magnetic). Recognize that energy is the ability to cause motion or create change.
PS.5. Give examples of how energy can be transferred from one form to another.

Light Energy

PS.12. Recognize that light travels in a straight line until it strikes an object or travels from one medium to another, and that light can be reflected, refracted, and absorbed.

Magnetic Energy

PS.10. Identify and classify objects and materials that a magnet will attract and objects and materials that a magnet will not attract.
PS.9. Recognize that magnets have poles that repel and attract each other.

Properties of Objects and Materials

PS.1. Differentiate between properties of objects (e.g., size, shape, weight) and properties of materials (e.g., color, texture, hardness).

Sound Energy

PS.11. Recognize that sound is produced by vibrating objects and requires a medium through which to travel. Relate the rate of vibration to the pitch of the sound.

States of Matter

PS.2. Compare and contrast solids, liquids, and gases based on the basic properties of each of these states of matter.
PS.3. Describe how water can be changed from one state to another by adding or taking away heat.


SIS2. Select and use appropriate tools and technology (e.g., calculators, computers, balances, scales, meter sticks, graduated cylinders) in order to extend observations.

SIS4. Conduct multiple trials to test a prediction. Compare the result of an investigation or experiment with the prediction.

SIS5. Recognize simple patterns in data and use data to create a reasonable explanation for the results of an investigation or experiment.

SIS6. Record data and communicate findings to others using graphs, charts, maps, models, and oral and written reports.


T/E.1. Materials and Tools

T/E.1.1. Identify materials used to accomplish a design task based on a specific property, i.e., weight, strength, hardness, and flexibility.
T/E.1.3. Identify and explain the difference between simple and complex machines, e.g., hand can opener that includes multiple gears, wheel, wedge gear, and lever.
