Electricity and Magnetism

BIGidea: Magnetism & electricity each have their own unique properties & operate by specific rules for many practical uses.

3.01 Observe and investigate the pull of magnets on all materials made of iron and the pushes or pulls on other magnets.

3.06 Describe and identify materials that are conductors and nonconductors of electricity

3.03 Design and test an electric circuit as a closed pathway including an energy source, energy conductor and an energy receiver.

3.05 Describe and explain parts of a bulb.

3.08 Observe and investigate the ability of electric circuits to produce light, heat, sound and magnetic effects.

3.07 Observe and investigate that parallel and series circuits have different characteristics.

 

Electricity: A form of energy that can produce light, heat, and

magnetism.

Electricity receiver: A component that uses the electricity from a

source to make something happen.

Electricity source: Something that provides electric energy to make

something happen.

Magnet: An object that sticks to iron.

Magnetism: A property of certain kinds of materials that causes

them to attract iron or steel.

Circuit: A pathway for the flow of electricity.

Closed circuit: A complete circuit through which electricity flows.

Conductor: A substance, commonly a metal such as copper or

aluminum, through which electricity will flow.

Current: The flow of electricity through a conductor.

Rocks and Minerals


What are minerals?

Minerals are natural. Each mineral has its own crystal and chemical makeup and physical qualities such as hardness and color.

 

What are rocks?

Rocks are made up of minerals. 

 

Identifying Minerals

Geologists try to find out what types of minerals are in rocks. They use properties to help them! Below are the mineral properties they use.

1. Hardness: hardness is determined by trying to scratch a mineral with different materials.   Minerals with large hardness numbers like 8, 9, or 10, can't be scratched.   Minerals with small hardness numbers like 1, 2, or 3 can be scratched easily with materials like a fingernail.

2. Color

3. Light properties ( transparent, translucent, opaque)

4. Magnetism

5. Streak: If you rub a mineral on unglazed white tile it can leave a streak.

                   3 types of rocks: Igneous, Sedimentary, and Metamorphic 

Igneous Rocks- forms when melted rock is cooled and hardened. Examples: granite, basalt, tuff, pumice, obsidian

Sedimentary Rocks- forms in layers from bits of older rocks, parts of animals, and/or plants. These collect in low areas or under water and harden into rocks. Examples: Limestone, sandstone, shale, conglomerate, breccia

Metamorphic Rocks- forms when either sedimentary, igneous, or earlier formed metamorphic rocks were put under pressure and heat deep in the earth's crust. Examples: marble, slate, gneiss, schist
