Spring SAVY 2019, Day 2 – The Water-Energy Nexus (5th/6th)

Posted by on Monday, February 4, 2019 in Grade 5, Grade 6, SAVY blog.

Today was a great second class.

·     We first reviewed some of the material from last week, including the pros and cons of various hydropower systems and the scientific method.

·     Then, we continued working on our hydropower experiment (determining the influence of potential energy on turbine output voltage).

·     Then we went through some of the equations and vocabulary related to buoyancy to show how forces associated with water may change with salinity.

·     Then we constructed our floating rafts and tested the amount of mass that could be held by the rafts in both pure water and salty water.

·     Then we closed out the day with a discussion on the ethics associated with polluting rivers and the legal decisions that may protect rivers.

·     Then we wrote journal entry summaries of the day and the class was dismissed.

Looking forward to next week!
