MO.2. Properties and Principals of Force and Motion

2.1. The motion of an object is described by its change in position relative to another object or point

2.1.B. An object that is accelerating is speeding up, slowing down, or changing direction
2.1.B.a. Scope and Sequence - Forces and Motion: Describe Earth's gravity as a force that pulls objects on or near the Earth toward the Earth without touching the object

2.2. Forces affect motion

2.2.A. Forces are classified as either contact (pushes, pulls, friction, buoyancy) or non-contact forces (gravity, magnetism), that can be described in terms of direction and magnitude
2.2.A.b. Scope and Sequence - Forces and Motion: Describe magnetism as a force that can push or pull other objects without touching them
2.2.A.c. Scope and Sequence - Forces and Motion: Measure (using non-standard units) and compare the force (i.e., push or pull) required to overcome friction and move an object over different surfaces (i.e., rough, smooth
2.2.B. Every object exerts a gravitational force on every other object
2.2.B.a. Scope and Sequence - Forces and Motion: Describe Earth's gravity as a force that pulls objects on or near the Earth toward the Earth without touching the object
2.2.D. Newton's Laws of Motion explain the interaction of mass and forces, and are used to predict changes in motion
2.2.D.a. Scope and Sequence - Forces and Motion: Describe the direction and amount of force (i.e., direction of push or pull, strong/weak push or pull) needed to change an object's motion (i.e., faster/slower, change in direction)
2.2.F. Work transfers energy into and out of a mechanical system
2.2.F.a. Scope and Sequence - Forces and Motion: Compare and describe the amount of force (i.e., more, less, or same push or pull) needed to raise an object to a given height, with or without using inclined planes (ramps) of different slopes
2.2.F.b. Scope and Sequence - Forces and Motion: Compare and describe the amount of force (i.e., more, less, or same push or pull) needed to raise an object to a given height, with or without using levers
2.2.F.c. Scope and Sequence - Forces and Motion: Apply the use of an inclined plane (ramp) and/or lever to different real life situations in which objects are raised

MO.3. Characteristics and Interactions of Living Organisms

3.1. There is a fundamental unity underlying the diversity of all living organisms

3.1.B. Organisms progress through life cycles unique to different types of organisms
3.1.B.a. Scope and Sequence - Life Cycles of Animals: Identify and sequence life cycles (birth, growth, and development, reproduction and death) of animals (i.e, butterfly, frog, chicken, snake, dog)
3.1.B.b. Scope and Sequence - Life Cycles of Animals: Record observations on the life cycle of different animals (e.g., butterfly, dog, frog, chicken, snake)

MO.5. Processes and Interactions of the Earth's Systems (Geosphere, Atmosphere, and Hydrosphere)

5.1. Earth's systems (Geosphere, atmosphere, and hydrosphere) have common components and unique structures

5.1.A.a. Scope and Sequence - Earth Materials: Rocks and Minerals: Observe and describe the physical properties (e.g., odor, color, appearance, relative grain size, texture, absorption of water) and different components (i.e., sand, clay, humus) of soils
