Virginia Grade 3 science standards

3.1 Scientific and engineering practices: define a simple design problem, design and build a device, and analyze data from tests of an object to determine whether it works as intended.

Lessons: Build It, Launch It (Can you drop an egg without breaking it?, What makes a paper plane fly farthest?, How does a rocket push itself into space?)

Practice: Build It, Launch It workbook · Your Senses: How Does Your Body Know? workbook · Simple Circuits: Make It Light Up workbook · Earth Day Investigations: Make Your School Better workbook · Monsoon Science: Rain, Sun and the Nón Lá workbook · Evidence Lab workbook · How Your Body Works workbook · Keep It Cool: Ice, Insulation and Staying Comfortable workbook · Winter Science: Ice, Snow and Staying Warm workbook · Think Like a Scientist: The Scientific Method workbook · Test the Claim: Science Facts, Myths and AI Answers workbook · Steppe Science: Staying Warm on the Kazakh Steppe workbook

3.2 Investigate and understand that the direction and size of force affects the motion of an object, including that the net force determines how an object moves. The balloon rocket and paper plane tests.

Lessons: Build It, Launch It (Can you drop an egg without breaking it?, What makes a paper plane fly farthest?, How does a rocket push itself into space?) · Pushes, Pulls and Magnets (Why does a ball stop rolling?, Can a magnet work through a table?, How far will a paper clip jump?)

Practice: Build It, Launch It workbook · Pushes, Pulls and Magnets workbook · Forces at Work: Gravity, Resistance, Levers and Pulleys workbook

3.3 Solids dissolve more easily in hot water than in cold water (a partial match: salt and sugar solutions for the crystal lesson).

Lessons: Earth and Sky at Home (Where do rainbows come from?, How do crystals grow?, How does a cloud form?) · Kitchen Chemistry for Families · Winter Science at Home (Can you make frost in a can?, Why does salt melt ice?, What's inside a snowflake?)

Practice: Kitchen Chemistry for Families workbook · Clean Water Challenge: Mixtures, Dissolving and Separating workbook · Solids, Liquids and Gases workbook · Grade 4 Rocks and Minerals

3.4 Adaptations may be behavioral or physical (a partial, lower-grade match: whiskers, echolocation and owl ears).

Lessons: Your Senses: How Does Your Body Know? · Winter Science: Ice, Snow and Staying Warm

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

3.5 Aquatic and terrestrial ecosystems support a diversity of organisms; relationships exist among organisms in an ecosystem (a lower-grade match: the schoolyard count).

Lessons: Our Living Planet (Can a jar keep itself alive?, Where does rain come from?) · Food Webs: Who Eats Whom?

Practice: Our Living Planet workbook · Food Webs: Who Eats Whom? workbook

3.7 There is a water cycle: the energy from the sun drives the water cycle and it involves specific processes. The cloud-in-a-jar lesson shows condensation (partial).

Lessons: Earth and Sky at Home (Where do rainbows come from?, How do crystals grow?, How does a cloud form?) · Our Living Planet (Can a jar keep itself alive?, Where does rain come from?) · Solids, Liquids and Gases (Where does a puddle go?, Why does ice float?)

Practice: Our Living Planet workbook · The Water Cycle, Start to Finish workbook · Weather Detectives workbook

3.8 Natural events and humans influence ecosystems: human activity affects air, water and habitats, and water is limited and needs conserving (a lower-grade match).

Lessons: Rocks and Erosion: How Land Changes Shape · Earth Day Investigations: Make Your School Better

Practice: Earth Day Investigations: Make Your School Better workbook · Our Changing Planet: Resources and Human Impact workbook
