Students wrote down four different science project ideas for heat transfer investigations.
Which project idea is an investigation about heat transfer through conduction?
Question 7 options:
Project Idea A
Place a thermometer 10 cm from an identified heat source.
Place a second thermometer 50 cm from the heat source.
Place a third thermometer 100 cm from the heat source.
Record the temperature of each thermometer.
Turn on the heat source.
Record the temperature of each thermometer after 2 minutes, 3 minutes, and 4 minutes.
Project Idea B
Hold a pinwheel 30 cm above a hear source.
Make observations about the movement of the pinwheel.
Hold the pinwheel 60 cm away from the same heat sources.
Make observations about the movement of the pinwheel.
Compare observations.
Project Idea C
Poke a hole into the side of a shoebox.
Insert a thermometer through the hole.
Cover the shoebox with white paper.
Record the temperature.
Turn on light over the shoebox.
Record the temperature after 2 minutes and 5 minutes.
Project Idea D
Record the surface temperature of a strip of aluminum, a thin strip of wood, and a strip of plastic.
Place all three materials in a preheated frying pan.
After two minutes remove each material from the pan.
Record the surface temperature of each material.
