Explore the laws of motion using a simple fan cart. Use the buttons to select the speed of the fan and the surface, and press Play to begin. You can drag up to three objects onto the fan cart. The speed of the cart is displayed with a speedometer and recorded in a table and a graph. 5 Minute Preview
Free-Fall Laboratory
Investigate the motion of an object as it falls to the ground. A variety of objects can be compared, and their motion can be observed in a vacuum, in normal air, and in denser air. The position, velocity, and acceleration are measured over time, and the forces on the object can be displayed. Using the manual settings, the mass, radius, height, and initial velocity of the object can be adjusted, as can the air density and wind. 5 Minute Preview
PS3.1.S.PS3.6.1.3: : Describe the relationship between the strength of a force on an object and the resulting effect, such as the greater the force, the greater the change in motion.

PS3.2: : Motion
PS3.2.S.PS3.6.2.2: : Explain that an object's motion can be tracked and measured over time and that the data can be used to describe its position.
Distance-Time Graphs
Create a graph of a runner's position versus time and watch the runner complete a 40-yard dash based on the graph you made. Notice the connection between the slope of the line and the speed of the runner. What will the runner do if the slope of the line is zero? What if the slope is negative? Add a second runner (a second graph) and connect real-world meaning to the intersection of two graphs. 5 Minute Preview

Free Fall Tower
Recreate Galileo's famous experiment by dropping objects off the Tower of Pisa. You can drop ping pong balls, golf balls, soccer balls or watermelons. Objects can be dropped in air or no air, with or without a parachute. The speed of each object is shown on a speedometer and a graph. 5 Minute Preview

PS4: : The growth of scientific knowledge in Physical Science has been advanced through the development of technology and is used (alone or in combination with other sciences) to identify, understand and solve local and global issues.
PS4.1: : Design Technology
PS4.1.S.PS4.6.1.1: : Understand that scientific principles are used in the design of technology.
Pendulum Clock
Find the effect of length, mass, and angle on the period of a pendulum. The pendulum is attached to a clock that can be adjusted to tell time accurately. The clock can be located on Earth or Jupiter to determine the effect of gravity. 5 Minute Preview
PS4.3: : Social Issues (Local and Global), Energy, Power, and Transportation, Manufacturing
PS4.3.A.S.PS4.6.3.1: : Explain how a battery changes chemical energy into electrical energy.
Energy Conversions
Where does energy come from? How does energy get from one place to another? Find out how electrical current is generated and how living things get energy to move and grow. Trace the path of energy and see how energy is converted from one form to another. 5 Minute 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.
