200
2 forces acting when an object floats
What is gravity and buoyancy?
200
formula to calculate density
What is mass divided by volume
200
formula to calculate buoyant force
What is weight in air minus weight in water?
200
why some salad dressings must be shaken before using
What is ingredients have different densities, creating layers?
300
flows in eddies versus a streamlined flow
What is the difference between turbulent and laminar flow?
300
confined system with liquid versus with air
What is hydraulics compared to pneumatics?
300

What is 4 g/cubic cm?
300
volume of a liquid with a mass of 180 g and a density of 2 g/mL
What is 90 mL?
300
mass of object with density of 10 g/cubic cm and volume of 2 cubic cm
What is 20 g?
400
displacement method of calculating volume of irregular objects
What is placing object in a liquid and getting before and after volume measurements; then subtract?
400
scuba diver floats where/how with positive, negative and neutral buoyancies
What is on the surface, at the bottom, stays at mid-level?
400
basis and form of qualitative observations
What is on the 5 senses and written notes/sketches?
400
basis and form of quantitative observations
What is measurements and charts/graphs?
400
description of placement of particles in solids, liquids and gases
What is densely, closely packed, more spaced apart and widely spaced apart, by particle theory?
500
Archimedes Principle
What is buoyant force on object immersed in liquid equals weight of the fluid displaced?
500
how particle theory explains which flows faster, water or air
What is air because it is a gas, and the particles are spaced widely apart and flow the most freely?
500
explains why fish don't die in winter in Haliburton lakes
What is water is most dense and a liquid at 4 degrees celcius and therefore sinks to the bottom; ice floats on the top?
500

What is the cause agent, making something happen?
500
dependent variable acts in this manner in an investigation
What is the effect, what is measured to have shown some change?
