1: Unit 5.1 Ecosystems & Matter Cycling
1.1: How does a nurse log help other things live and grow?
1.1.3: Lesson 3: How can we measure how much a plant has grown?
Growing Plants
Investigate the growth of three common garden plants: tomatoes, beans, and turnips. You can change the amount of light each plant gets, the amount of water added each day, and the type of soil the seed is planted in. Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. Determine what conditions produce the tallest and healthiest plants. Height and mass data are displayed on tables and graphs. 5 Minute Preview
1.1.4: Lesson 4: How can we figure out what plants need to grow?

Food Chain
In this ecosystem consisting of hawks, snakes, rabbits and grass, the population of each species can be studied as part of a food chain. Disease can be introduced for any species, and the number of animals can be increased or decreased at any time, just like in the real world. 5 Minute Preview

Prairie Ecosystem
Observe the populations of grass, prairie dogs, ferrets and foxes in a prairie ecosystem. Investigate feeding relationships and determine the food chain. Bar graphs and line graphs show changes in populations over time. 5 Minute Preview
2: Unit 5.2 Matter Properties
2.1: How can we make water healthy for all living things?
2.1.1: Lesson 1: How can we tell if water is healthy or unhealthy?
Water Contamination - Elementary School
There has been an outbreak of legionnaires’ disease in a small town. This disease is caused by legionella bacteria that proliferate in contaminated water supplies. Students take on the role of a civil engineer to investigate how the water treatment plant has failed to get rid of all the contaminants in the water and design a new method. Video Preview

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.
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
