Vertebrate Skeletons
In this biology activity, students examine the human skeleton and then classify animal bones according to their similar function.
Curated OER
Hominoid Cranium Comparison
Students describe, measure and compare cranial casts from contemporary apes (chimpanzees and gorillas, typically), modern humans and fossil "hominids" (erect and bipedal forms evolutionarily separated from apes).
Curated OER
Differences
Students observe and compare a variety of living things and pictures of living things to note their similarities and differences.
Curated OER
Classification
Students investigate how to classify items based on similar characteristics. They study the scientific system of classification.

Classifying Living Organisms into Kingdoms
Learners create a flip book that describes the basic characteristics of the five main animal kingdoms. They research the animal kingdoms, include examples of organisms for each kingdom and illustrate the finished text.
Curated OER
Dichotomous Key
Eighth graders use a dichotomous key to identify unknown fictitious organisms. They work individually during this exercise. The task is designed to take students approximately 15-25 minutes to complete.

Understanding Evolution: Homology and Analogy
In this understanding evolution worksheet, 9th graders define homology and analogy. Students compare and contrast similar structures in several given species.
Curated OER
Chromosome Fusion
Students see how patterns can reveal events of the past, thereby merging elements of both experimental and historical science.
Curated OER
Evolution Explorations
Students compare characteristics of animals and human beings. In this biology instructional activity, students observe an animal and record their observations. They infer whether the evolution theory is true or not.
Curated OER
Homology: Where Does The Evidence Lead
Learners are introduced to the topic of homology. In groups, they read a case study and compare different drawings of early vertebrate emryos. They work together to answer discussion questions and label the various parts of each embryo.

Why Do We Need Vitamin C in Our Diet?
Students compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of an...
Curated OER
Classifying Organisms within Kingdoms
Learners examine animal kingdom classifications. They discuss how animals are placed into kingdom classifications and compare similarities and differences of animals within a kingdom.
