comuucing LIIC LAPITICIIL
In this task, you will carry out a controlled experiment to investigate how different materials-sand and water-
cool over time. You'll also consider the effect of mass on heat transfer. Then you will analyze and explain your
results.
Note: This task requires a mass scale and three thermometers. It may need to be carried out in a school lab.
Review & how to use scales and thermometers.
Question 1: Hypothesis and Data Collection
Begin this task by forming a hypothesis about the outcome of the experiment. Then conduct the
experiment and document the results.
Estimated time to complete: 2 hours
You will need these materials e.
A Stay safe! Make sure you wear your goggles. Handle hot water with care to avoid burns from water
splashing or from steam. Use care when inserting glass thermometers into the sand. Adult supervision is
required.
Part A
In the experiment, you will heat up 50 grams of cold sand and 50 grams of cold water by adding hot water.
Will the kind of material-sand or water-affect the temperature change? State your hypothesis.
