Question

name: _____________________________ date: ___________
virtual explore: energy transformation systems
energy is found in many forms all around you; chemical energy in food, electrical energy in appliances,
light energy in lamps, and radiant energy from the sun are all examples. energy is constantly being
transformed from one type to another in systems. a system is a group of interacting elements that
work together to perform a task. as these types of energy are transformed, energy is not created or
destroyed. it is conserved and changes from one form to another. in todays activity, you will explore
two different systems and learn how energy is conserved and transformed.
procedure
part i: electric circuit system

1. open the simulation, and click the \start\ button. you will first explore how energy is transformed

within an electric circuit.

1. complete the chart as you explore this part of the simulation.

location	battery	wire	bulb

part ii: food web system

1. a food web shows the energy flow from one organism to another in an ecosystem. as you explore

the energy transformations in the food web system simulation, complete the chart below, showing
how energy moves from the sun all the way to the ringtail.

energy is converted from radiant energy to chemical energy.

leftover chemical energy is converted to heat energy energy that is ne for b processes.

sun → oak tree → squi

Explanation:

To solve the energy transformation questions in the "Virtual Explore: Energy Transformation Systems" activity, we analyze each part:

Part I: Electric Circuit System

For an electric circuit:

• Battery: Stores chemical energy (from the chemicals inside it) which is converted to electrical energy to power the circuit.
• Wire: Transmits electrical energy (electrons flow through the wire).
• Bulb: Converts electrical energy into light energy (and some heat energy, though light is the primary useful output here).

Part II: Food Web System

In a food web, energy flows from the Sun:

• Sun to Oak Tree: The oak tree (a producer) uses photosynthesis to convert radiant energy (from sunlight) into chemical energy (stored in glucose/sugars).
• Leftover Chemical Energy: When organisms use chemical energy for life processes, unused (leftover) chemical energy is often released as heat energy (due to metabolic processes like respiration).

Filling the Charts:

Part I Chart:

Location	Type of Energy Found at Each Location
Wire	Electrical Energy
Bulb	Light Energy (and Heat Energy)

Part II (Food Web) Blanks:

• "Energy is converted from \(\boldsymbol{\text{radiant}}\) energy to \(\boldsymbol{\text{chemical}}\) energy." (Sun to oak tree: photosynthesis).
• "Leftover chemical energy is converted to \(\boldsymbol{\text{heat}}\) energy..." (metabolic waste energy is released as heat).

These answers align with the principles of energy transformation: energy is conserved and changes form (e.g., chemical → electrical → light; radiant → chemical → heat), following the law of conservation of energy.
