Intro:
We put ice water into glass beakers and plastic beakers. The ice water was about 40 degrees F. We also put hot water in glass and plastic beakers. The hot water was about 140 degrees F. We collected temperature data with a temperature sensor for five minutes straight.
Claim:
Ice water does not change temperature very much after five minutes of just sitting there while hot water changes temperature a lot more in five minutes of just sitting there.
Evidence:
Using glass and plastic beakers ice water only changed about five degrees F in five minutes. While hot water in both glass and plastic beakers dropped about 45 degrees F in five minutes!
Reasoning:
We noticed that the ice water still had ice in it after five minutes of data collection. That means that the water still had to be cold, which explains why the ice water did NOT increase in temperature very much. The hot water lost over 45 degrees F in five minutes because it transferred more heat to the classroom.
Our data supports my claim because the ice water, whether in a glass beaker or a plastic beaker barely changed temperature in five minutes, five degrees F on average, while the hot water, whether in a glass beaker or plastic beaker, lost about 45 degrees F in five minutes.
