Tennessee Academic Standards for Science (2022). Every lesson comes with a printable teacher guide and student sheet.
Life Sciences
8.LS4.1 Using evidence from the geologic timescale, 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.
Lessons: Natural Selection: How Living Things Change Over Time (How do fossils show life has changed?) (partly)
Practice: Natural Selection: How Living Things Change Over Time workbook
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.
Lessons: Natural Selection: How Living Things Change Over Time (How do fossils show life has changed?)
Practice: Natural Selection: How Living Things Change Over Time workbook
8.LS4.3 Construct an explanation based on evidence that explains how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing.
Lessons: Natural Selection: How Living Things Change Over Time (Why do some animals survive and others don't?, What did the Grants find on the Galápagos?)
Practice: Natural Selection: How Living Things Change Over Time workbook
8.LS4.5 Obtain, evaluate, and communicate information about the technologies that have changed the way humans use artificial selection to influence the inheritance of desired traits in other organisms.
Lessons: Natural Selection: How Living Things Change Over Time (How fast can people change a species?) (partly)
Practice: Natural Selection: How Living Things Change Over Time workbook
Physical Sciences
8.PS2.5 Plan and conduct an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
Lessons: Forces and Motion: Crash, Push and Stop (Why do you lurch forward when a bus stops?, Why does a heavier cart hit harder?)
