2: Understand relationships of the properties of objects and materials, position and motion of objects, and transfer of energy to explain the physical world.

2.a: Determine how the properties of an object affect how it acts and interacts.

Free Fall Tower

2.c: Investigate the motion of an object in terms of its position, direction of motion, and speed.

2.c.2: Force required to move an object using appropriate devices (e.g., spring scale)

2.c.3: Variables that affect speed (e.g., ramp height/length/surface, mass of object)

Measuring Motion

2.c.4: Effects of an unbalanced force on an object?s motion in terms of speed and direction

2.d: Categorize examples of potential energy as gravitational (e.g., boulder on a hill, child on a slide), elastic (e.g., compressed spring, slingshot, rubber band), or chemical (e.g., unlit match, food).

Energy Conversions

2.e: Differentiate between the properties of light as reflection, refraction, and absorption.

2.e.1: Image reflected by a plane mirror and a curved-surfaced mirror

Heat Absorption

2.f: Describe physical properties of matter (e.g., mass, density, boiling point, freezing point) including mixtures and solutions.

2.f.1: Filtration, sifting, magnetism, evaporation, and flotation

Magnetism

2.g: Categorize materials as conductors or insulators and discuss their real life applications (e.g., building construction, clothing, animal covering).

Conduction and Convection

3: Predict characteristics, structures, life cycles, environments, evolution, and diversity of organisms.

3.b: Research and classify the organization of living things.

3.b.2: Function of the major parts of body systems (nervous, circulatory, respiratory, digestive, skeletal, muscular) and the ways they support one another

Circulatory System

3.d: Distinguish between asexual and sexual reproduction.

3.d.3: Sexual reproduction (e.g., eggs, seeds, fruit)

Flower Pollination

3.e: Give examples of how consumers and producers (carnivores, herbivores, omnivores, and decomposers) are related in food chains and food webs.

Forest Ecosystem
Prairie Ecosystem

4: Develop an understanding of the properties of Earth materials, objects in the sky, and changes in Earth and sky.

4.d: Describe changes caused by humans on the environment and natural resources and cite evidence from research of ways to conserve natural resources in the United States, including (but not limited to) Mississippi. Examples of Mississippi efforts include the following:

4.d.2: The Natural Resource Enterprises (NRE) Program of the Department of Wildlife and Fisheries and the Cooperative Extension Service at MSU educate landowners in the Southeast about sustainable natural resource enterprises and compatible habitat management practices.

4.e: Predict the movement patterns of the sun, moon, and Earth over a specified time period.

Solar System

4.f: Compare and contrast the physical characteristics of the planets (e.g., mass, surface gravity, distance from the sun, surface characteristics, moons).
