8.PS2: Motion and Stability: Forces and Interactions

8.PS2.1: Design and conduct investigations depicting the relationship between magnetism and electricity in electromagnets, generators, and electrical motors, emphasizing the factors that increase or diminish the electric current and the magnetic field strength.

Electromagnetic Induction

8.PS2.2: Conduct an investigation to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

8.LS4: Biological Change: Unity and Diversity

8.LS4.1: Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change in life forms throughout Earth’s history.

Human Evolution - Skull Analysis

8.LS4.2: Construct an explanation addressing similarities and differences of the anatomical structures and genetic information between extinct and extant organisms using evidence of common ancestry and patterns between taxa.

Human Evolution - Skull Analysis

8.LS4.3: Analyze evidence from geology, paleontology, and comparative anatomy to support that specific phenotypes within a population can increase the probability of survival of that species and lead to adaptation.

Natural Selection

8.LS4.4: Develop a scientific explanation of how natural selection plays a role in determining the survival of a species in a changing environment.
