A material that allows thermal energy to pass through it.
A material that stops or slows the flow of thermal energy.
A series circuit relies on a single path to allow the energy to travel. If any part of the circuit is cut or open none of the lights will work.
A parallel circuit has branches that allow some lights to work even while others do not.
Scholars need to know that electrical energy can be transferred or changed into other types of energy.
Example:
A material that allows electrical energy to pass through it.
Examples:
A material that stops or slows the flow of electrical energy.
Examples:
Water becomes trapped in the crack of a rock, the water then freezes and expands outwards. This causes the rock to crack, this process will be repeated multiple times.
Glaciers are formed of many layers of snow and ice. Glaciers appear to be sitting still, they are actually moving. The weight of a glacier and the pull of gravity will cause it to move slowly down the mountain, sort of like a very slow moving river. As the glacier slowly slides down the mountain side it weathers and erodes the mountain. The glacier takes a lot of rock and sediment with it to be deposited it at the bottom of the mountain.
The movement or force of water is constantly weathering and eroding the Earth's surface. Here are a few examples of the these forces, such as, the waves of an ocean, precipitation, and the constant flow of a river.
The constant force of wind continues to change the Earth's surface through weathering and erosion.
Gravity pulls everything down, including rocks and sediment.
Animals including humans weather and erode our Earth's surface. A few examples are increased farming removes the plant cover leaving the soil open to erosion from water and wind. Over grazing can all so cause erosion when herds eat all the plant cover exposing the soil to wind and water.
Plants can cause weathering by sprouting and growing in soil that has collected in the cracks of a rock. As the plant grows, the roots extend and spread the crack until the rock eventually breaks.
U-shaped valley's are formed when a glacier is pulled down the side of a mountain by gravity. As the glacier slowly moves down the mountainside it weathers and erodes the side of the mountain forming a U-shaped valley.
Formed through the weathering and erosion of a river. The force of the water and the grinding of rocks and stones cut down into the river bed to carve out a valley.
A delta is formed from sediment flowing down a river when the river runs into an ocean or a lake the sediment is deposited. As the water enters the ocean/lake, it slows down and spreads out, and so the particles of sediment build up.

Sand dunes are formed from the movement of wind. There needs to be a large amount of loose sand in an area with hardly any vegetation, enough wind to move grains of sand and some kind of obstacle to make the blowing sand lose its momentum and deposit a new place.
Canyons are formed through many years of weathering and erosion from the constant movement of a river. Canyons have step side called cliffs.
Any materials that people use from the Earth and the atmosphere. The students need to know that everything we have and use comes from some type of natural resources.
Resources that can be replaced in a short period of time.
