Forces & Gravity
Snowshoes work by distributing this over a larger area
Weight or mass
The scientist who defined the three Laws of Motion
Isaac Newton
With only a cup of water, small magnet, needle, and a cork or piece of Styrofoam, you can make this handy wayfinding tool
Compass
Electricity is a result of charged these
Particles
A solar oven can be made from a car sunshade, or a carboard box and this reflective material
Tinfoil
A force besides gravity
Applied Force
Friction Force
Normal Force
Drag Force
Magnetic Force
Elastic Force
Tension Force
This force is the opposite of friction
Applied Force
Magnets can attract or do this to each other
Repel
The build-up of an electrical charge on the surface of an object
Static Electricity
Black, grays, and white are not colours, but these
Shades
The two objects that an astronaut dropped on the moon to prove Galileo's theory on gravity
Feather & Hammer
Newton's Third Law of Motion states that every action force has an equal and opposite this
Reaction
The northern lights, or Aurora borealis, is the result of solar radiation reacting with this
Earth's Magnetic Field
If electricity can't move through an object then it is an insulator, if it can move through an object then it is this
Conductor
Gamma-ray, x-ray, ultraviolet, infrared, optical, and radio waves are all forms of this type of energy
Light or
Radiant Energy
When we did our gravity experiment outside by dropping objects from a height of three meters, we recorded times they took to fall and calculated this for each object
Air Resistance or K
Newton's First Law of Motion states that an object in motion will stay in motion and an object at rest will stay at rest - unless acted on by this
Unbalanced Force
Outside or External Force
Magnetism is the motion of this
Electrical Charges or
Spinning Electrons
This generates electricity by allowing a controlled amount of water to flow through a dam, using the force of gravity, to turn a turbine and is how almost all electricity is generated in Manitoba
Hydroelectric Dam
The name of the very old tower where Galileo did his gravity experiments by dropping objects with different weights
The Leaning Tower of Pisa
The name of Newton's Second Law of Motion
Law of Acceleration
Earth's magnetic field is a result of this
Movement of liquid iron in Earth's outer core
The form of energy generated from pumping cold water down to deeper and warmer parts of the Earth, then pumping up the heated water to generate electricity at the surface
Geothermal Energy
