Texas Essential Knowledge and Skills (TEKS) for Science. Every lesson comes with a printable teacher guide and student sheet.
Matter and energy
3.6(A) Measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float. The unit measures how far a magnet's pull reaches.
Lessons: Pushes, Pulls and Magnets (Why does a ball stop rolling?, Can a magnet work through a table?, How far will a paper clip jump?)
3.6(B) Describe and classify samples of matter as solids, liquids, and gases. The oobleck lesson tests when the mixture acts like a solid and when like a liquid (partial).
Lessons: Kitchen Chemistry for Families
Practice: Kitchen Chemistry for Families workbook · Test It, Choose It: Materials workbook
3.6(C) Predict, observe, and record changes in the state of matter caused by heating or cooling, such as ice becoming liquid water or condensation forming on the outside of a glass. Covers frost on a can, salt melting ice and snowflake formation.
Lessons: Earth and Sky at Home (Where do rainbows come from?, How do crystals grow?, How does a cloud form?) · Winter Science at Home (Can you make frost in a can?, Why does salt melt ice?, What's inside a snowflake?) · Winter Science: Ice, Snow and Staying Warm · Solids, Liquids and Gases (Where does a puddle go?, Why does ice float?)
Practice: Earth and Sky at Home workbook · Winter Science at Home workbook
Force, motion, and energy
3.7(A) Demonstrate and describe forces acting on an object in contact or at a distance, including magnetism, gravity, and pushes and pulls.
Lessons: 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: Pushes, Pulls and Magnets workbook
Earth and space
3.10(A) Compare and describe day-to-day weather in different locations, including air temperature, wind direction, and precipitation (an adjacent-grade match: schoolyard temperature survey).
Lessons: Weather Detectives (Why does a chinook feel like spring in January?, Is it hotter by the slide?, Why do farmers care about the last frost?)
Practice: Weather Detectives workbook
3.10(B) Investigate and explain how soils such as sand and clay are formed by weathering of rock (an adjacent-grade match: how rocks become sand).
Lessons: Rocks and Erosion: How Land Changes Shape
Practice: Rocks and Erosion: How Land Changes Shape workbook · Living with Water: Salt, Rice and the Mekong workbook
Organisms and environments
3.12(A) Explain how temperature affects animal growth and behaviour through migration and hibernation. The snow-den lesson looks at animals sheltering under the snow (partial).
Lessons: Winter Science: Ice, Snow and Staying Warm
Practice: 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 · Your Senses: How Does Your Body Know? workbook · Groundhog Day Shadow Science
3.13(A) Explore and explain how external structures and functions of animals enable them to survive in their environment (an adjacent-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
