The pictures below show the temperatures recorded by two lab groups from the same thermometer at 3:00 p.m. on the same day.

Why did the groups get different results?

• One of the groups did not use the correct language to record its measurement.

• The groups did not use the same thermometer to make their measurements.

• One of the groups measured the temperature at a different time of day.

• The groups decided to use a different unit to record the temperature.

Kim knows that most things that create light also create heat. She wants to know how much heat is given off by the bulb on her desk lamp while she is doing her homework. Which of the following would be the best way for Kim to measure how much heat the bulb puts out?

• Place a glass of ice under the lamp to see whether it will melt.

• Place a black shirt under the lamp and feel how hot it gets.

• Place her hand under the lamp to see if her hand gets warm.

• Place a thermometer under the lamp and measure the temperature.

The table shows the temperatures taken with a thermometer of a bucket of water during different times of the day.
