1.1.1.B.SP.1: Conduct an investigation to demonstrate changes of state.
1.1.1.B.SP.1: Conduct an investigation to demonstrate changes of state.
Phases of Water
Heat or cool a container of water and observe the phase changes that take place. Use a magnifying glass to observe water molecules as a solid, liquid, or gas. Compare the volumes of the three phases of water. 5 Minute Preview
1.1.1.C.SP.1: Describe solid, liquid, and gas states of matter in terms of the properties of shape and volume.

1.1.1.E.SP.1: Describe and diagram the changes of state of water using the water cycle.
1.1.1.E.SP.1: Describe and diagram the changes of state of water using the water cycle.
Water Cycle
Control the path of a drop of water as it travels through the water cycle. Many alternatives are presented at each stage. Determine how the water moves from one location to another, and learn how water resources are distributed in these locations. 5 Minute Preview
2: Energy: Understandings of the physical world are deepened by investigating matter and energy.
2.1: How can forces relate to changes in movement?
2.1.1: Students investigate and explain how forces affect the movement of objects.
3: Earth Systems: Understandings of the living world, Earth, and space are deepened by investigating natural systems and their interactions.
3.1.1.B.SP.1: Represent how the movement of water and wind changes Earth’s surface over time.
Rock Cycle
Play the role of a piece of rock moving through the rock cycle. Select a starting location and follow many possible paths throughout the cycle. Learn how rocks are formed, weathered, eroded, and reformed as they move from Earth's surface to locations deep within the crust. 5 Minute Preview
Weathering
Weathering is the breakdown of rock at Earth's surface through physical or chemical means. Students will learn about the different types of mechanical and chemical weathering, then use a simulation to model the effects of weathering on different types of rocks in varying climate conditions. 5 Minute Preview
River Erosion
Explore how river erosion affects landscapes in the short term and over long periods of time. Describe the features of mountain streams and meandering rivers, and use a floating barrel to estimate current speed. Witness the changes that occur as mountain streams erode downward and meandering rivers erode from side to side. 5 Minute Preview
Erosion Rates
Explore erosion in a simulated 3D environment. Observe how the landscape evolves over time as it is shaped by the forces of flowing water. Vary the initial landscape, rock type, precipitation amount, average temperature, and vegetation and measure how each variable affects the rate of erosion and resulting landscape features. 5 Minute Preview
3.1: What visible changes can be identified by examining Earth’s surface?
3.1.1: Students analyze changes in Earth’s surface and explain how its layers hold stories of the past.
3.1.1.B.SP.1: Represent how the movement of water and wind changes Earth’s surface over time.

4: Living Systems: Understandings of the living world, Earth, and space are deepened by investigating natural systems and their interactions.
4.1: How do plants and animals interact?
4.1.1: Students analyze and describe how plants and animals interact with each other and within environments.
6: Scientific Methods: Investigation of the physical world is enhanced through the use of scientific methods that attempt to remove human biases and increase objectivity.
6.1: How can investigation help to deepen understanding in science?
6.1.1: Students relate investigation to building knowledge.

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.
How Free Gizmos Work
Start teaching with 20-40 Free Gizmos. See the full list.
Access lesson materials for Free Gizmos including teacher guides, lesson plans, and more.
All other Gizmos are limited to a 5 Minute Preview and can only be used for 5 minutes a day.
Free Gizmos change each semester. The new collection will be available January 1 and July 1.
