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 into calculating the surface area of cylinders. We also began to find the volume of right prisms and cylinders. Our buddy Rob with Math Antics helped introduce to topic visually.
This worksheet finding the volume of mixed shapes is due for a homework check tomorrow. Those looking for extra practice can work on this additional worksheet. These will set us up well as we look into beginning our 3D Shape Sculpture math project this week, where students will be creating physical combinations of multiple 3D shapes. A digital copy of the project description can be found here.
