Science

 


During our look at Rocks and Minerals, we will be looking identifying the difference between the two. We will also be discussing the 3 types of rocks: Sedimentary, Igneous, and Metamorphic. By conductings experiements, we will be determining the characteristics of each type of rock. We will also discuss the uses of rocks and minerals.



 

Vocabulary

metamorphic rocks-rocks formed when heat and pressure change one kind of rock into another.

sedimentary rocks- rocks formed over time by the hardening of layers of sediment like mud, shell particles, pieces of bone, and rock fragments.

igneous rocks- rocks that are formed when melted rock cools and hardens, either under or above the surface.

lava- molten rock found on top of Earth's crust

magma- molten rock underground

minerals- solid, pure substances found in the Earth that combine to form rocks. Minerals are made by a process deep within the Earth.

fossils-prints of plants and animals that lived long ago

gemstones- valuable minerals like diamonds, rubies and opals

rock cycle- the natural process by which rocks are created and changed to form new rocks

opaque- transmits no light

translucent- transmits varying degrees of light

transparent-transmits virtually all the light that is shined at them

hardness-the ability of a mineral to resist being scratched

luster-the shine of a mineral

intrusive- cools slowly, and creates coarse grained rocks

extrusive-cools quickly, and creates fine grained rocks

cleavage-the way a mineral breaks

 

 

 

 

 

and Magnets

Our electricity and magnet unit will show us how the two work together to make a light work. Open and closed circuits will be some of our vocabulary words. We will be working with static electricity as well.

 

Vocabulary

poles- ends of a magent

lodestone- a natural magnet

attract- pull together

repel-push away

magnet- an object that has the property of attracting certain material

electricity- a kind of energy

conductor- a material electricity moves through easily

insulator- a material that does not allow the flow of electricity

electric circuit- a path in which an electric current can move

open circuit- a path is broken, current cannot flow through

closed circuit- a path which current flows through

static electricity- electricity produced through static charges

electric current- a continuous flow of electric charges

 

Our Life Science and Habitats unit will allow us to disect some owl pellets. Students are able to get a hands-on opportunity to see how a food chain actually works. We will also be creating a food chain of our own using  pictures of different animals.

Vocabulary

Ecosystem:  a system formed by the interaction of a community of organisms with their environment

Food Chain:  a series of organisms interrelated in their feeding habits, the smallest being fed upon by a larger one, which in turn feeds a still larger one, etc.

Food Web:  a series of organisms related by predator-prey and consumer-resource interactions

Community:  organisms of interacting populations occupying a given area

Population:  all the individuals of a specific type of organism living in a given area

Biome:  a major regional or global biotic community, such as a grassland or desert, characterized chiefly by the dominant forms of plant life and the prevailing climate

Herbivore:  a living thing that eats only plants

Carnivore:  an animal that eats flesh

Omnivore:  an animal whose normal diet includes both plants and animals

Pollution:  introduction of harmful substances or products into the environment

Predator:  any organism that exists by preying upon other organisms

Prey:  an animal hunted or seized for food by a carnivorous animal

pH:  a measure of the acidity or alkalinity of a solution

Producer:  an organism, such as a plant, that is able to produce its own food from inorganic substances

Consumer:  an organism, usually an animal, that feeds on plants or other animals

Decomposer:  an organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances
