Mississippi Grade 3 science standards

L.3.1.1 Examine evidence to communicate information that the internal and external structures of animals (e.g., heart, stomach, bone, lung, brain, skin, ears, appendages) function to support survival, growth, and behavior.

Lessons: How Your Body Works (Why does your heart beat faster when you run?, What happens to your lunch?, How does your arm bend?) · Keep It Cool: Ice, Insulation and Staying Comfortable (How do animals stay warm in the sea and cool in the desert?) · Your Senses: How Does Your Body Know? (How do animals sense what we can't?) · Winter Science: Ice, Snow and Staying Warm (How do animals stay warm in winter?)

Practice: How Your Body Works workbook · Keep It Cool: Ice, Insulation and Staying Comfortable workbook · 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 · Groundhog Day Shadow Science

L.3.1.2 Examine evidence to communicate information that the internal and external structures of plant (e.g., thorns, leaves, stems, roots, or colored petals) function to support survival, growth, behavior, and reproduction.

Lessons: Flowers, Fruit and Seeds: How Plants Make More Plants (What is a flower really for?, Is a tomato a fruit?, How can a seed travel without legs?) (partly)

L.3.2.4 Obtain and communicate data to provide evidence that plants and animals have traits inherited from both parent organisms and that variations of these traits exist in groups of similar organisms (e.g., flower colors in pea plants or fur color and pattern in animal offspring).

Lessons: Like Parent, Like Baby? Traits and Families (Why don't puppies from the same parents look the same?)

Practice: Like Parent, Like Baby? Traits and Families workbook

L.3.4.3 Analyze and interpret data to explain how variations in characteristics among organisms of the same species may provide advantages in surviving, finding mates, and reproducing (e.g., plants with larger thorns being less likely to be eaten by predators or animals with better camouflage colorations being more likely to survive and bear offspring).

Lessons: Survival Clues: Fossils, Groups and Changing Habitats (Why do some animals in a family survive better?)

Practice: Survival Clues: Fossils, Groups and Changing Habitats workbook

P.3.5.2 Develop and use models to communicate the concept that matter is made of particles too small to be seen that move freely around in space (e.g., inflation and shape of a balloon, wind blowing leaves, or dust suspended in the air).

Lessons: Earth and Sky at Home (How do crystals grow?, How does a cloud form?) (partly) · Kitchen Chemistry for Families (Why do the blobs in a lava lamp go up and down?, What makes a volcano erupt?) (partly) · Winter Science at Home (Can you make frost in a can?) (partly) · Living with Water: Salt, Rice and the Mekong (How do salt farmers turn the sea into salt?, How do rice terraces stop a mountain washing away?, How can a house stay dry when the Mekong floods?)

P.3.6.1 Compare and contrast the effects of different strengths and directions of forces on the motion of an object (e.g., gravity, polarity, attraction, repulsion, or strength).

Lessons: Build It, Launch It (How does a rocket push itself into space?) (partly) · Pushes, Pulls and Magnets (Why does a ball stop rolling?) (partly) · Forces at Work: Gravity, Resistance, Levers and Pulleys (Do heavy things really fall faster?, How can a small push lift a big load?) (partly)

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

P.3.6.4 Define and solve a simple design problem by applying scientific ideas about magnets (e.g., can opener, door latches, paperclip holders, finding studs in walls, magnetized paint). Use an engineering design process to define the problem, design, construct, evaluate, and improve the magnet.

Lessons: Pushes, Pulls and Magnets (How far will a paper clip jump?)

Practice: Pushes, Pulls and Magnets workbook
