North Carolina Grade 4 science standards

ESS.4.1.1 Use models to explain the cause of day and night based on the rotation of the Earth on its axis.

Lessons: Sun, Earth and Moon (Why do we have day and night?)

Practice: Sun, Earth and Moon workbook · Stars and the Night Sky workbook · The Reason for the Seasons: Tilt, Daylight and the Solstice workbook

ESS.4.1.2 Use models to explain the repeating pattern of the phases of the moon (new, crescent, quarter, gibbous, and full).

Lessons: Sun, Earth and Moon (Why does the Moon change shape?)

Practice: Sun, Earth and Moon workbook · The Reason for the Seasons: Tilt, Daylight and the Solstice workbook

ESS.4.2.1 Carry out investigations to classify minerals using tests for the physical properties of hardness, color, luster, cleavage and streak.

Lessons: Rocks and Erosion: How Land Changes Shape (Are all rocks the same?) (partly)

ESS.4.2.3 Use models to explain changes in Earth's surface over time (to include slow changes of erosion and weathering, and fast changes of earthquakes, landslides, and volcanic activity).

Lessons: Restless Earth: Fossils, Soils, Volcanoes and Plates (Where do volcanoes and earthquakes happen?, What do moving plates do, and can a building survive?) (partly) · Rocks and Erosion: How Land Changes Shape (Can water carve a canyon?, What protects a hillside from washing away?, How do rocks become sand?) (partly) · Living with Water: Salt, Rice and the Mekong (How do rice terraces stop a mountain washing away?) (partly)

Practice: Rocks and Erosion: How Land Changes Shape workbook · Living with Water: Salt, Rice and the Mekong workbook

ESS.4.3.2 Engage in argument from evidence to explain how humans can adapt their behavior to live in changing environments (e.g. recycling wastes, establishing rain gardens, planting native species to prevent flooding and erosion).

Lessons: Earth Day Investigations: Make Your School Better (What's in our garbage?, How much water does a dripping tap waste?) (partly) · Living with Water: Salt, Rice and the Mekong (How do rice terraces stop a mountain washing away?, How can a house stay dry when the Mekong floods?) (partly)

Practice: Living with Water: Salt, Rice and the Mekong workbook · Restless Earth: Fossils, Soils, Volcanoes and Plates workbook · Rocks and Erosion: How Land Changes Shape workbook

LS.4.1.1 Use models to explain that plants and animals have external structures that function to support survival.

Lessons: Flowers, Fruit and Seeds: How Plants Make More Plants (What is a flower really for?, How can a seed travel without legs?) (partly) · Keep It Cool: Ice, Insulation and Staying Comfortable (How do animals stay warm in the sea and cool in the desert?) (partly) · Winter Science: Ice, Snow and Staying Warm (How do animals stay warm in winter?) (partly)

Practice: Flowers, Fruit and Seeds: How Plants Make More Plants workbook · Keep It Cool: Ice, Insulation and Staying Comfortable workbook · Winter Science: Ice, Snow and Staying Warm workbook · How Your Body Works workbook · Your Senses: How Does Your Body Know? workbook · Groundhog Day Shadow Science

LS.4.1.2 Use models to explain that animals receive different types of information through their senses, process the information, and respond to the information in different ways.

Lessons: Your Senses: How Does Your Body Know?

Practice: Your Senses: How Does Your Body Know? workbook

LS.4.2.2 Analyze and interpret data to explain how fossils suggest ideas about Earth's early environment.

Lessons: Restless Earth: Fossils, Soils, Volcanoes and Plates (How do fossils form, and what can they tell us?)

Practice: Restless Earth: Fossils, Soils, Volcanoes and Plates workbook

PS.4.1.1 Ask questions to summarize the relationship of magnetic interactions between two objects not in contact with each other.

Lessons: Pushes, Pulls and Magnets (Can a magnet work through a table?, How far will a paper clip jump?)

Practice: Pushes, Pulls and Magnets workbook

PS.4.2.2 Use models to explain a simple electrical circuit and the necessary components.

Lessons: Simple Circuits: Make It Light Up (Can you light a bulb with one wire?, Why do some string lights all go out at once?)

Practice: Simple Circuits: Make It Light Up workbook · Keep It Cool: Ice, Insulation and Staying Comfortable workbook · Winter Science: Ice, Snow and Staying Warm workbook · Steppe Science: Staying Warm on the Kazakh Steppe workbook

PS.4.2.3 Carry out investigations on common materials to classify them as insulators or conductors of electricity.

Lessons: Simple Circuits: Make It Light Up (What lets electricity through?)

Practice: Simple Circuits: Make It Light Up workbook · Keep It Cool: Ice, Insulation and Staying Comfortable workbook · Winter Science: Ice, Snow and Staying Warm workbook · Steppe Science: Staying Warm on the Kazakh Steppe workbook

PS.4.3.1 Carry out investigations to infer the path light travels from a light source to a mirror and how it is reflected (by the mirror) using different angles.

Lessons: Bouncing Light: Mirrors, Water and Colour (How can a mirror steer a beam of light?)

Practice: Bouncing Light: Mirrors, Water and Colour workbook · Your Senses: How Does Your Body Know? workbook

PS.4.3.2 Carry out investigations to explain how light is refracted and absorbed.

Lessons: Earth and Sky at Home (Where do rainbows come from?) (partly) · Bouncing Light: Mirrors, Water and Colour (Why does a pencil look broken in water?, What colours are hiding in white light?)

Practice: Grade 4 Light and Colour
