Independant variable: Temperature of the room (three temperatures)
Dependant variable: Length of the candle after it has burned for 30 minutes
Constants (control variables): Type and length of candle, diameter of candle, and time that the candle is allowed to burn.
Need help putting this into graph form...
Never mind, I think I got it.
To represent this experiment in graph form, you would typically use a line graph. The independent variable, temperature of the room, will be plotted on the x-axis, while the dependent variable, length of the candle after burning for 30 minutes, will be plotted on the y-axis.
Here are the steps to create the graph:
Step 1: Choose appropriate scales for the x-axis and y-axis. Ensure that the scales allow you to clearly visualize the data points.
Step 2: Mark and label the temperature values on the x-axis. Since there are three temperatures, you will have three labeled points on the x-axis.
Step 3: Mark and label the length of the candle after burning for 30 minutes on the y-axis. The values on the y-axis will depend on the measurements taken during the experiment.
Step 4: On the graph, plot the data points obtained from the experiment. For each temperature, mark the corresponding length of the candle after 30 minutes on the y-axis.
Step 5: Connect the data points for each temperature using a straight line. This will show the trend or relationship between the room temperature and the length of the candle after burning for 30 minutes.
Step 6: Add a title to the graph, such as "Effect of Room Temperature on Candle Length After 30 Minutes."
Step 7: Label the x-axis as "Room Temperature (°C)" and the y-axis as "Length of Candle after 30 Minutes (cm)."
Remember to clearly display the data points, draw the lines connecting them, and label the axes. This will help convey the relationship between the room temperature and the length of the candle after burning for 30 minutes in a graphical format.
