Algebra 1, Algebra 2 and Physical Science
What would happen to the sea life if the temperature of the ocean were just five degrees different? Have you ever wondered why the ocean temperature is so constant?
Through two experiments, students will see first hand the effect of ambient temperature on a mass (in this case, water). Students will explore the different temperature changes of fresh water and salt water, learning about density along the way. To supplement the experimental data, students will utilize Newton’s Law of Cooling to model the cooling temperature over time. Students will utilize logarithms to find the constant rate of change and then develop a conceptual understanding of logarithms. The lesson concludes with a conversation about homeostasis and the huge effect of such a temperature shift and a conversation about the salinity of the oceans of the world. You’re sure to find tons of great ideas in this new interdisciplinary unit.
NASA News! Here is a great link to further explore salinity in oceans: http://aquarius.gsfc.nasa.gov/overview-mission.html NASA is launching a new initiative to ocean salinity from space! This is a great extension to the ”Cool It” lesson.
