Sample Learning Goals

[text]

For Teachers

Introduction:

The LOL Energy Diagram Master Template is versatile, allowing educators to tailor simulations to their specific teaching goals and adapt them to various classroom environments. Its intuitive interface makes it easy for teachers to create customized learning experiences that resonate with their students. Here's how the simulation aligns with this teaching methodology: 

L: Initial State
The left "L" Diagram prompts students to focus on the initial state of the system. This visualization provides a starting point for students to analyze and understand the energy distribution within the system. By examining the energy stores depicted in the initial state diagram, students gain insights into the starting conditions and the potential energy transformations that may occur.

O: Observation of Closed system
The middle diagram, represented by the letter "O," illustrates the energy transfers within the system. Through dynamic simulations and interactive features, students can observe how energy moves and transforms throughout the system. This hands-on approach allows students to actively engage with the concept of energy transfer, enhancing their understanding of physics principles through real-time observation and experimentation.

L: Final State
Finally, the right "L" diagram displays the final state of the system. This visualization offers a conclusion to the energy dynamics observed throughout the simulation. By analyzing the energy stores depicted in the final state diagram, students can assess the overall outcome of the energy transfers and transformations within the system. This step allows students to consolidate their learning and draw conclusions about the changes that occurred.

One of the key features of the LOL Energy Diagram Master Template is its adherence to the principle of energy conservation. This ensures that energy is accurately tracked and accounted for in each scenario, providing students with a comprehensive view of how energy behaves in different situations.

Another key feature of the LOL Energy Diagram Master Template is its flexibility. Teachers have the ability to edit the answer key at the bottom of the page, making it easy to tailor simulations to different scenarios and learning outcomes. This empowers educators to create personalized learning experiences that cater to the unique needs of their students.

  • You may want to use the interactive below to help in the thinking process.
    1. Drag the "Internal Energy" store into the initial "L" state if appriopriate. This represents the thermal energy in the ingredients.
    2. Drag the "Internal Energy" store into the final "L" state for the ingredients. This represents the thermal energy gained by the ingredients as they are heated during the baking process.
    3. Drag the "Chemical Energy" store into the final "L" state for the ingredients. This represents the chemcial energy gained by the ingredients as they are heated during the baking process.
    4. Select the Energy Transfer In Combo box:
      • The energy is transferred by heating from the oven to the ingredients, increasing their thermal energy as they absorb heat from the hot air inside the oven.
    5. Adjust the Energy Stores and Transfers to suitable values where Conservation of Energy (COE) is observed. The thermal energy transferred from the oven is stored in the ingredients, raising their temperature and facilitating the baking process.
    6. When the word "Balanced" appears, it means COE is observed! This indicates that the energy transferred from the oven has been fully converted into the thermal energy store of the ingredients, with no energy lost to other processes.

    you may want to use the interactive below to help in the thinking process.
    1. Drag the "Internal Energy" store into the initial L state. This represents the internal energy stored in the hot tea initially.
    2. Drag the "Thermal Energy" store into the final L state. This represents the energy stored in the hot tea finally.

  • You may want to use the interactive below to help in the thinking process.
  • Drag the "Kinetic Energy" store into the initial "L" state. Is there KE initial? if no, keep it at 0 J.
  • Drag the "Gravitational Potential Energy" store into the final "L" state. This represents the gravitational potential energy stored in the system of the girl on the swing and Earth when she reaches her highest point.
  • Select the Energy Transfer In:The energy is transferred into the girl is it a mechanical force, which causes the swing to move?
    Adjust the Energy stores and transfer until to suitable values where Conservation of Energy (COE) is observed. The push provides energy that is stored first as kinetic energy and then as gravitational potential energy at the highest point.
  • When the word "Balanced" appears, it means COE is observed! This indicates that the energy transferred into the system has been fully converted to gravitational potential energy stores, with no energy lost to the surroundings.
  • exportG3LampHeatUpwithHeatandLightOut.zip exportG3LampHeatUpwithHeatandLightOut/ You may want to use the interactive below to help in the thinking process.

    2. Drag the "Internal Energy" store in the final "L" state. These represent the internal energy in the lamp.
    3. Select the Energy Transfer In:
      • The energy is transferred electrically from the battery to the lamp.
    4. Adjust the Energy Stores and Transfers adjust to suitable values where Conservation of Energy (COE) is observed. 
    5. When the word "Balanced" appears, it means COE is observed! This indicates that the energy transferred into the lamp has been fully converted into the internal store, with light and heat transfer out of the system.
