These 2 simple machines are variations of an incline plane.
What are screws and wedges?
This is needed to calculate density.
What is mass and volume?
This is the first step when using a compound microscope.
What is secure the slide using stage clips?
This is the approximate speed of light in space.
What is 300 000 km/s?
This can change salt into freshwater, using a solar still or reverse osmosis, but has some environmental concerns and can be expensive

This mirror converges light and creates a real image.
What is concave mirror?
This determines the direction water will flow in a watershed.
What is elevation and landforms?
This law states that a pressure change at any point in a confined incompressible fluid is transmitted equally on all parts throughout the fluid.
What is Pascal's Law?
If air pressure at sea level is greater than the pressure at the top of a mountain, this happens to a bag of chips when taken to the top of a mountain.
This is responsible for carrying oxygen in the circulatory system.
What are red blood cells?
This lens diverges light and creates a virtual image.

Valley Glaciers are in the mountains and these ones are typically found in the Plains region.
What are Continental Glaciers?
This is the primary advantage of using reducing gears in a machine.
What is to increase force?
This force acts perpendicular to a certain surface area.
What is pressure?
These tiny air sacs in the lungs are where gas exchange occurs.
What are alveoli?
Who had the theory that light rays leave our eyes and sense the surroundings?
Who is Pythagoras?
Melted glacial ice flowing into cracks in rocks is one way for this to happen.
What is glacial erosion?
