A guide to the wonders of grade 5
This is almost unheard of! Well, ok, maybe not. But we can use this as an opportunity to learn about Calgary's pilot project to de-ice roads with a beet juice solution rather than a salt based solution. Here are some articles below. 5C Students are organizing their information into google slides and will present some of their answers on Thursday May 23.
After reading the 3 articles, answer these questions: Why is Calgary covering some of its roads with beet juice brine this year? What type of mixture is beet juice brine? What were they using before beet juice brine? What are some environmental benefits from changing the way Calgary ices its roads? How does beet juice brine help to save Calgary’s cars? What is corrosion? Why is it that salt helps to get rid of ice?
