Question

plan your research question

1. what is one relevant dependent variable (dv) that you can measure with a number in the simulation to help answer questions we have about matter changes and energy transfer in a wire? remember, a dependent variable is a variable in an investigation that you can measure.
2. what is one relevant independent variable (iv) that you can choose to change in the sim to help answer questions we have about matter changes and energy transfer in a wire? remember, an independent variable is a variable in an investigation that you change.
3. a research question can often be stated as “what is the effect of (independent variable) on (dependent variable)?” write your research question using two variables below.

what is the effect of __________________________________ on __________________________________?
independent variable (from #7) dependent variable (from #6)
conduct your investigation

1. investigate a relationship between the independent and dependent variables you chose:

a. run the simulation and notice the value of your dependent variable.
b. pause the simulation and increase the independent variable value.
c. run the simulation again and note any change in the dependent variable.
d. repeat steps b and c until you are sure youve identified a pattern. describe the pattern you identified below.
e. controlled variables are factors that we keep constant so we can see how the independent variable affects the dependent variable. list at least 2 or 3 variables that you didnt change while investigating your relationship.

Explanation:

1. One possible dependent variable could be the temperature of the wire, which can be measured numerically and is related to energy transfer.
2. An independent variable could be the current flowing through the wire, which can be changed in the simulation.
3. The research question would be "What is the effect of current (independent variable) on the temperature of the wire (dependent variable)?"

9.
A - D: By following the steps of running, pausing - changing, and re - running the simulation, one may find that as the current increases, the temperature of the wire also increases.
E: Controlled variables could include the length of the wire, the material of the wire, and the ambient temperature around the wire.

Answer:

1. Temperature of the wire
2. Current flowing through the wire
3. What is the effect of current on the temperature of the wire?

9.
A - D: As current increases, wire temperature increases.
E: Length of wire, material of wire, ambient temperature
