Mississippi College & Career Readiness Standards
MS.L.2. GRADE TWO: Life Science
Reproduction and Heredity
L.2.2. Students will demonstrate an understanding of how living things change in form as they go through the general stages of a life cycle.
L.2.2.1. Use observations through informational texts and other media to observe the different stages of the life cycle of trees (i.e., pines, oaks) to construct explanations and compare how trees change and grow over time.
MS.P.2. GRADE TWO: Physical Science
Motions, Forces, and Energy
P.2.6. Students will demonstrate an understanding of how the motion of objects is affected by pushes, pulls, and friction on an object.
P.2.6.2. Generate and answer questions about the relationship between (1) friction and the motion of objects and (2) friction and the production of heat.
P.2.6.3. Develop a plan to change the force (push or pull) of friction to solve a human problem (e.g., improve the ride on a playground slide or make a toy car or truck go faster). Use an engineering design process to define the problem, design, construct, evaluate, and improve the plan.
