Summary
Students experiment with an online virtual laboratory set at a skate park. They make predictions of graphs before they use the simulation to create graphs of energy vs. time under different conditions. This simulation experimentation strengths their comprehension of conservation of energy solely between gravitational potential energy and kinetic energyEngineering Connection
During this activity, student predict behavior before they discover the real behavior of the man in a virtual skate park. This application gives them context for learning about potential and kinetic energy. Predicting the behavior of something based on prior knowledge is an important skill for engineers. When engineers are designing, they make predictions about how structures, devices and processes will function before they build them. This activity helps students develop this very important skill.
Learning Objectives
After this activity, students should be able to:
- Apply their background knowledge to begin solving the challenge.
- Relate kinetic energy with gravitational potential energy and heat energy.

| Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system. Alignment agreement: | Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system's total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms. Alignment agreement: At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.Alignment agreement: These relationships are better understood at the microscopic scale, at which all of the different manifestations of energy can be modeled as a combination of energy associated with the motion of particles and energy associated with the configuration (relative position of the particles). In some cases the relative position energy can be thought of as stored in fields (which mediate interactions between particles). This last concept includes radiation, a phenomenon in which energy stored in fields moves across space.Alignment agreement: | Energy cannot be created or destroyed—it only moves between one place and another place, between objects and/or fields, or between systems.

Introduction/Motivation
In today's activity, we first consider our previous knowledge on the subject, which can be applied to solving the challenge. Then, we determine exactly what we need to learn in order to learn about how energy can be transferred. You will be getting a worksheet, on which you first record your own thoughts in the form of a line graph. Afterwards, we will organize into lab groups and work on the virtual lab using an online simulation.
So let's jump start our initial expectations (get the initial screen shot on the screen in front of the class, and draw an energy-time graph on the board). Draw a graph of what you expect potential energy to be doing over three cycles. In another color, draw what you expect kinetic energy to be doing over the same time period. So far this is in the absence of friction. Now lets draw another plot for what we expect to happen with friction present. Where does heat come into play?
Procedure
Background
This activity introduces students to the concept of conservation of energy and the relationship of friction to this interaction.
Before the Activity
Make copies of the Energy Skate Park Worksheet. one per student.
Test student computers to make sure they are able to run the simulation at http://phet.colorado.edu/en/simulation/energy-skate-park.
With the Students
- Describe the prediction portions of the worksheet with students.
- Divide the class into small lab groups and have students share their thoughts with each other.
- Have students perform the simulation for the following situations: A) frictionless on Earth, B) with friction on Earth, C) on Jupiter with and without friction, D) in space without friction.
- Give students time to experiment with the simulation.
- Conclude with a class discussion so students can share and compare their results and conclusions. Ask the Investigating Questions.
Assessment
Assess student comprehension from their group discussion contributions and completeness and accurcy of their worksheet answers.
Investigating Questions
- How does friction affect both kinetic and potential energy? Does this contradict the law of conservation of energy?
- How does the changing of the gravitational field affect the conservation of energy that you observe?
- How does the changing of mass (changing of skater) affect the conservation of energy that you observe?
Activity Scaling
- For lower grades, provide more time for group discussions.
- For upper grades, ask students to relate a mathematical relationship between kinetic energy and gravitation kinetic energy, with and without friction.
