Hello Grade 8's! Last week in science, we took a look at the particle model of matter, viscosity, density and buoyancy. Slides shown in class can be viewed by clicking here his link . Make sure you know and review these! On Thursday, we looked at the density of different substances in the creation of our density tower. We found that the most dense substance, corn syrup, sank to the bottom, below the other substances. This was followed by dish soap, water, vegetable oil and rubbing alcohol, the least dense substance, resting on top. On Friday, buoyancy was introduced by Bill Nye . This week, we will continue to look into buoyancy and compressibility. Our density tower - Rubbing alcohol (dyed red), Vegetable Oil (yellow/white), Water (dyed blue), Dish Soap (green), Corn Syrup (brown). This is what we should have expected from our Coke density investigation today. Why do you think our regular Coke can floated when we tried it in class? Last week in math, we looked...
