Science 8 Unit 5: Relationships among Forms of Energy

Student Learning Objectives: Michigan K-12 Science Standards for Middle School
MS-PS3-1 Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
MS-PS3-2 Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. 
MS-PS3-5 Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.​

Gizmo: Heat Transfer by Conduction​
​​Thoughtful Classroom Self Reflection: Effort Tracker
​
Post Lab Summary in your science notebook
Explain how the energy from a container of hot water transfers through a metal rod into a container of cooler water.   Key Words to use in paragraph: collision and conduction
Conduction is like a relay race where particles "hand off" something (energy, electrons, vibrations, etc.) from one to another.

Gizmo: ​Conduction and Convection
​​Self Reflection: Effort Tracker

Post Lab Summary in your science notebook:
Explain why energy is transferred more quickly in the process of convection than by the process of conduction .  ​

​Key Ideas to use in paragraph: distance over which a  process occurs,  conduction is on micro scale , transport is macro or global scale
convection is the movement of molecules in a fluid in a circular pattern, rapidly transporting both the energy and matter of the fluid

Gizmo: Energy Conversion in a System

  • Gizmo A: Calculating Joules of Potential Energy applied to system, observing relationship between temperature change and energy added.

  • Gizmo B: Changing the Mass of the Cylinder changes the Joules of Energy, observing pattern between amount of energy and amount of temperature change.
    • Gizmo B Post Lab Analysis: Graphing Data helps us see Relationships​
    • Gizmo B "Energy Conversion in a System" Lab Summary
      ​​​​Write a paragraph responding to the following three prompts:
      Describe the relationship between the change in mass of the cylinder and the gravitational potential energy being provided by the cylinder.​
      Describe the relationship between the amount of energy supplied by the cylinder and the temperature change of the water.
      Think about and make a Prediction about what would happen to the relationship between temperature change of water and amount of energy. If we supplied the same amount of energy in another form would the change in temperature be affected?

  • Gizmo C: Observing effect of energy on temperature change compared to starting temperature of system and amount of water in the device.
    • Challenge (Optional): Calculating Specific Heat of Water and Considering "Specific Heat" as an intrinsic property of materials
