Properties of Water Test - Tuesday February 18

We have been learning about the properties of water in order to help us understand how solutes are dissolved in solvents and how that, in turn, contributes to water contamination on Earth.

We have identified 4 properties of water that we are using to help us explain real-life situations. In the example opposite, we discussed how 2 of the properties of water explain why there is so little "fresh" water on Earth. On the test on Tuesday, these are the kinds of real-life questions we will need to answer.

Here are some more possible questions to practice:

use your understanding of the properties of water to explain why water drops join together on windshields
use your understanding of the properties of water to explain why a closed, full water bottle will expand when frozen
use your understanding of the properties of water to explain why water drops are shaped the way they are
use your understanding of the properties of water to explain why some stains wash out of clothes and other stains do not

Gator Gardens Aquaponics System Design

Today we were fortunate to be joined by Mr. Tyler Graham who is working with us to design our aquaponics system. Mr. Graham is currently VP at E.L. Crossley but over the past 6 years, he worked to design and build a first class aquaponics program at Westlane S.S.

We learned that we need to create the right bacterial culture in our fish tank before we can start growing our plants, and that nitrates in the fish poo need to be converted to nitrites the plants will use as nutrients.

Our next steps are to:

provide measurements and drawings for the frame for our aquaponics system to the construction class at E.L. Crossley so they can build our design.
buy goldfish for our fish tank to get the bacterial culture going
prepare for a pitch presentation to investors now that we know exactly what our costs and products are going to be
