BIO2.LS4: : Biological Change: Unity and Diversity
BIO2.LS4.1: : Use models of viruses, prokaryotes, and eukaryotes to ask questions about characteristics of living things and analyze theories regarding the origin of life on Earth. Construct an argument from evidence supporting the idea that eukaryotes could not exist on the planet if not for prokaryotes.

Cell Types
Explore a wide variety of cells, from bacteria to human neurons, using a compound light microscope. Select a sample to study, then focus on the sample using the coarse and fine focus controls of the microscope. Compare the structures found in different cells, then perform tests to see if the sample is alive. 5 Minute Preview

Virus Lytic Cycle
Release a lytic virus in a group of cells and observe how cells are infected over time and eventually destroyed. Data related to the number of healthy cells, infected cells, and viruses can be recorded over time to determine the time required for the virus to mature within a cell. 5 Minute Preview
BIO2.LS4.2: : Using information based on the geologic time scale and history of life on Earth, look for patterns in changes in organisms over time and explain how these patterns support the theory of evolution.

Human Evolution - Skull Analysis
Compare the skulls of a variety of significant human ancestors, or hominids. Use available tools to measure lengths, areas, and angles of important features. Each skull can be viewed from the front, side, or from below. Additional information regarding the age, location, and discoverer of each skull can be displayed. 5 Minute Preview
BIO2.LS4.3: : Use molecular data to construct cladograms depicting phylogenetic relationships between major groups of organisms.
![Screenshot of Cladograms](/Assets/img/blank.gif)
Cladograms
Based on the similarities and differences between different organisms, create branching diagrams called cladograms to show how they are related. Use both morphological data (physical traits) and molecular data to create the simplest and most likely cladograms. Five different sets of organisms are available. 5 Minute Preview
BIO2.LS4.13: : Interpret data supporting current plant classification schemes. Use a dichotomous key to identify plants based on variations in characteristics.
![Screenshot of Dichotomous Keys](/Assets/img/blank.gif)
Dichotomous Keys
Use dichotomous keys to identify and classify five types of organisms: California albatrosses, Canadian Rockies buttercups, Texas venomous snakes, Virginia evergreens, and Florida cartilagenous fishes. After you have classified every organism, try making your own dichotomous key! 5 Minute Preview
BIO2.LS4.23: : Design and carry out an investigation examining how major body systems interact to maintain homeostasis of nutrient, energy, water, waste, and/or temperature balance.
![Screenshot of Circulatory System](/Assets/img/blank.gif)
Circulatory System
Trace the path of blood through a beating heart and the network of blood vessels that supplies blood to the body. Take blood samples from different blood vessels to observe blood cells and measure the levels of oxygen, carbon dioxide, sugar, and urea. 5 Minute Preview
![Screenshot of Digestive System](/Assets/img/blank.gif)
Digestive System
Digestion is a complex process, involving a wide variety of organs and chemicals that work together to break down food, absorb nutrients, and eliminate wastes. But have you ever wondered what would happen if some of those organs were eliminated, or if the sequence was changed? Can the digestive system be improved? Find out by designing your own digestive system with the Digestive System Gizmo. 5 Minute Preview
![Screenshot of Homeostasis - High School](/Assets/img/blank.gif)
Homeostasis - High School
In the role of a physician assistant, students help a young man, named Anthony, who has Type II diabetes and high blood pressure. Students must make a diagnosis and then must apply the principles of filtration and homeostasis to help Anthony. Video Preview
BIO2.LS4.24: : Obtain and communicate information on how the nervous and endocrine systems in a model vertebrate organism coordinate body functions such as: growth and development; stimuli response and information transmission; and the maintenance of homeostasis.

About STEM Cases
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.
![Realtime reporting icon](/Assets/img/blank.gif)
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
![Time icon](/Assets/img/blank.gif)
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
![Save icon](/Assets/img/blank.gif)
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
![Grades icon](/Assets/img/blank.gif)
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
![Handbook icon](/Assets/img/blank.gif)
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
