Super Giants

Red giants

Bright and cool red giants

Some red giants are very bright but are cool this is because they have a lot of surface area.

Massive stars

Intermediate mass stars(our sun)

low mass stars (red Dwarfs)

Red dwarfs are much smaller than our sun and make up three-quarters of the stars in the milky way.

White dwarfs

A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter. It is also very dense and is as big as the earth.

Intermediate stars like our star will have a lifetimes that range between 50 million and 20 billion years. Nuclear reactions in these stars make most of the carbon and nitrogen in the universe. When intermediate-mass stars die, they blow off their atmospheres, dispersing such elements across space.

Massive stars are stars that are are 100-200 times bigger that our sun and is also 100-200 times more luminosity.

Red giants are 100 to 1,000 times the size of the sun today. And has 1,000-10,000 times the luminosity of the Sun.

Super giants are 60 times bigger than our star. This star has 30 000 more luminosity than earth.

Sun

The sun sun has 7 layers, The Sun has seven inner and outer layers. The inner layers are the core, radiative zone, and convection zone, while outer layers are the photosphere, the chromosphere, the transition region, and the corona.

Travel in space

Traveling in space takes a long time. And it also gets boring because you eat the same food everyday and you are stuck with the same people everyday. And you also must worry about wearing the same clothes.

Ecosystem

Living things/non living things

Air

Sand

Sea

Land

Land is what we humans live on and which we build our homes, cities, attractions and moany more.

The sea is what provides sea creatures or living things that live in the ocean a home. And is also used for sea transportation.

Sand is a very important factor in life we it in Building buildings, aquariums, artificial reefs and many more things.

Air is what we breathe and its what provides living things like plants and animals respiration which gives out carbon dioxide. This process gives animals and plants the energy to eat, grow, and live life.

Animals

Plants

Micro organisms

Micro organisms are organisms that exist in a cell form.

Plants are living they give us air that we breathe plants also eat carbon dioxide.

Animals are living things they are natures wanderers and they provide meat.

Abiotic factors

Soil

Nature

Sunlight

Temperature

Temperature is how we measure how hot or how cold the environment your in.

Sunlight is what the sun reflects on the earth which plants and animals live on.

Nature is the physical world plants, animals, the landscape, and other features and products of the earth, as opposed to humans or human creations.

Soil lets plants grow, allows gas exchanges to happen between the land and air, provides habitat for most of the organisms on Earth, holds and cleans water, recycles nutrients, and is used for constructing structures like buildings.

Chemistry

Matter

Physical and chemical properties

Atoms

Periodic table

molecules

A molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

The periodic table is also known as the table of element which contains as

Structure

An atom has a structure and all atoms have different structure if they are a different compound it will have a different structure.

Physical and chemical structures are is a way to describe a how a substance changes into a completely different substance are called chemical properties.

Matter is any substance that has mass and takes up space by having volume.

Electricity

circuit

Series

Voltage is shared

Current is the same everywhere.

If one bulb goes out, so does the other.

parallel

Voltage is the same for all branches

Current is shared.

If one bulb goes out, the other/s will stay on.

current

Measured in amps (amperes)

Is a flow of charged particles.

Conductors let current flow.

Insulators stop current from flowing.

Static

Electrons rubbed from one thing to another.

Charges can't move so charge builds up.

Charges move when circuit completed-shocks, sparks.

Resistance

Makes if hard for particles to move.

The more resistance the smaller the current.

Charges

positive

negative

Like (same) charges repel (push away).

Unlike (different) charges attract.
