Science Review4th and 5th Grade Standards

4th Grade Standards

Life Sciences All organisms need energy & matter to live and

grow. Living organisms depend on one another for

survival. Physical Sciences - Electricity and Magnetism

Earth SciencesWaves, wind, water, and ice shape and reshape

the Earth’s land surface.

4th Grade Life Science: All organisms need energy and matter to live and grow.

Plants are the primary source of matter and energy. Plants take energy from the sun, water,

and carbon dioxide, and by the process of photosynthesis, they make food, oxygen and energy.


Primary consumers eat plants Herbivores (first level consumers) are

animals that eat plants

Second and third level consumers are animals that eat other animals Carnivores

Decomposers recycle matter from dead plants and animals Break down dead plants and animals

(example: termites)

Most microorganisms, including bacteria, are harmless

to humans.


Competition Organisms may compete for food,

water, sunlight, and shelter. Sharing Resources

Many different organisms can use the same resource at the same time.

Symbiosis A mutually beneficial relationship

between different kinds of organisms.


Adaptations How are desert organisms adapted to a

dry climate? Desert plants and animals have special

adaptations that allow them to survive in a harsh environment.


4th Grade Physical Science: Electricity and Magnetism

Electricity How to design and build a series and

parallel circuit A series circuit only has one path for moving

charges; when the path is broken, the energy can’t flow.

A parallel circuit has two or more paths for moving charges.

Electricity Electrical energy can be converted to

heat, light, and motion The heat given off when something is

plugged in Flashlights Fans


Electricity Electrically charged objects

attract or repel each other

2 balloons rubbed with a piece of wool will have the same (like) electrical charge.

The balloons will move away from each other because like charges repel each other


Magnetism The space near a

magnet where magnetic forces act is called the magnetic field

Magnets have opposite poles at each end, and unlike poles attract; like poles repel


Magnetism: How to create a simple compass

and how to use it. A needle or some other wire-

like piece of steel (a straight paper clip, for example)

Something small that floats (a

piece of cork, the bottom of a Styrofoam coffee cup, a piece of plastic or a milk jug cap)

A dish, like a pie plate, 9 to 12” in diameter, with about an inch of water in it


The first step is to turn the needle into a magnet. The easiestway to do this is with another magnet -- stroke the magnet along the needle 10 or 20 times.

Magnetism:Place your float in the middle of your dish of water as shown below.The "float on water" technique is an easy way to create a nearly frictionless bearing. Center your magnetic needle on the float. It very slowly will point toward north. You have created a compass!


Magnetism: Electromagnetism

Wires carrying an electric current become magnets.

An electromagnet is a core wrapped with wires that carry current.

The ends of the electromagnet are magnetic only when there is current in the wire.

Generators use electromagnets to produce current (electricity) from motion.

Motors use electromagnets to convert electricity to motion.


Earth Science:Rocks and Minerals

Mohs’ hardness scale 1 is the softest (talc) 10 is the hardest

(diamond) Everything else is in

between them. Seashells can be found

within sedimentary rock.

Scientists only use hardness, luster, and streak when classifying minerals.

Earth Science:Waves, wind, water, and ice shape and

reshape Earth’s land surface

Erosion is the process that picks up sediment and moves it around. Moving water erodes

landforms, reshaping the land

Deposition is the process that leaves sediment in a different place.

Remains or traces of past life found in the crust are called fossils.

5th Life Science

Plants and animals have structures for respiration, digestion, waste disposal, and transport of materials. Plants use carbon dioxide (CO2) and

energy from sunlight to build molecules of sugar and release oxygen

cells break down sugar to obtain energy, a process resulting in carbon dioxide (CO2) and water (respiration).

5th Life Science Plants and animals have structures

for respiration, digestion, waste disposal, and transport of materials.

There are two ways in which materials can get in and out of the cells.

Passive transport: doesn’t require energy, water can go in and out of the cells by osmosis.

Water diffuses in and out of the cell Diffusion is when molecules move from an

area of high concentration to an area of less concentration. (example: egg and vinegar)

5th Life Science

Animals have structures for respiration, digestion, waste disposal, and transport of materials. Respiration: Is the

process in which organism get the oxygen they need and release carbon dioxide.

Organisms break down sugars to obtain energy they need.

5th Life Science

Animals have structures for respiration, digestion, waste disposal, and transport of materials.

Circulatory system: Blood circulates through the

heart, lungs and body Oxygenated blood is taken to

the heart from the lungs by the pulmonary vein

The heart pumps the blood to the body. Arteries take blood to all the cells in your body.

Vein bring back blood to the heart. Blood has waste material (carbon dioxide)

The pulmonary arteries take blood back to the lungs.

5th Life Science

Animals have structures for respiration, digestion, waste disposal, and transport of materials. The excretory system

is in charge of the liquid waste disposal

The kidney is the organ that is in charge of removing cellular waste from the blood.

5th Life Science

Animals have structures for respiration, digestion, waste disposal, and transport of materials.

In the digestive system food is broken down and digested to be used as energy

The process starts in the mouth where food is broken down by saliva, then it transported to the stomach by the esophagus.

In the stomach food continues to brake down by digestive juices.

In the small intestine the nutrients are absorbed.

The remains are then sent to the large intestine where waste is disposed and water is absorbed.

5th Grade Physical Science

Elements and their combinations account for all the varied types of matter in the world Matter has three states: Solid, liquid and gas

gaseous substances can change both shape and volume

water changes from a solid to a liquid when ice is freezing

water changes from a liquid to a gas when it is boiling

All matter is made out atoms


Elements and their combinations account for all the varied types of matter in the world All matter is made out atoms

Atoms can NOT be reduced chemically into anything smaller

Atoms can be rearranged in a chemical reaction

Atoms can NOT “go away” or “just appear”


Elements and their combinations account for all the varied types of matter in the world

Salt can be dissolved in water combining an acid and a base forms water and a salt

Mixtures Combination of 2 or more substances that do NOT chemically

bond with each other

Compounds two or more elements together (think compound word or

rearranging letters in the alphabet) the variety of compounds in the human body are formed as

the 6 elements that are used as the “building blocks” / the atoms are organized to form different molecules


Elements and their combinations account for all the varied types of matter in the world Elements

Are made of just one kind of atoms The Periodic Table contain elements with

similar chemical properties single elements are listed on the table steel is a mixture of two elements on the

table/aka alloy

5th Grade Earth Science

Water on Earth moves between the oceans and land through the processes of evaporation and condensation.

Water vapor must cool and condense around dust particles for clouds to form

Rain falls when water droplets grow large enough to fall to the ground

Most of the water on Earth is in the oceans and, therefore, is saltwater

Water condenses in clouds. The condensed water then forms raindrops, which fall back to Earth as precipitation.

Drinking water can be stored in reservoirs for year-round As water evaporates, the salt is left behind. Because the lake

is smaller than the ocean, similar evaporation rates would leave significantly less water in the lake, making it saltier.

Earth Science: The Water Cycle

Earth Science: Weather/Air Pressure

Air pressure decreases as the distance from Earth’s surface increases

Uneven heating of Earth causes winds

Weather maps are used to make predictions over a short time period

Heat from the warm water provides energy for a hurricane to develop and moist air conditions are also necessary

Atmospheric pressure decreases as an object moves away from the surface of Earth. (example: a weather balloon released rises into the air & gets bigger, as the gas inside expands
