sun

The Sun is the only star in our solar system. It is the centre of our solar system, and its gravity holds the solar system together. its Temperature: 5,973°C to 15,000,000°C.   
          




 mercury


At a distance of only about 1/3 of Earth's distance to Sun, Mercury is the first planet in our Solar System. With a diameter of only 4880 kilometres (3032 miles) Mercury is the smallest planet in the Solar System. It is barely bigger than our Moon. Not only is Mercury the smallest planet, it is also shrinking!





Venus

  • Venus is the second closest planet to The Sun. It is the hottest planet in the Solar System. There are yellow clouds on Venus. Venus is the only planet in our Solar System that rotates Clockwise. A day on Venus lasts 243 Earth Days.





Earth


    • Earth is not flat, but it's not perfectly round either. The days are getting longer. There weren't always several continents. Earth's icy times. The driest place on Earth. Earth's gravity isn't uniform. In the past, sea levels were very different. Our sun has a voracious appetite.







 Mars


  • Mars is also known as the Red Planet. Mars is named after the Roman god of war. Mars has 2 moons called Deimos and Phobos. Mars is the 4th planet from the sun. Mars is smaller than Earth with a diameter of 4217 miles.

                                                                                                                                                                                                                  





Jupiter


  
  • Jupiter is the 5th planet away from The Sun. It is the biggest planet in our Solar System. Jupiter has rings, but they're too faint to see very well. Jupiter has 80 moons. Jupiter is a Gas Giant. A day on Jupiter is super fast. A year on Jupiter is the same as 11.8 Earth years.






Saturn

  • Saturn is huge. You cannot stand on Saturn. Its beautiful rings are not solid. Some of these bits are as small as grains of sand. The rings are huge but thin. Saturn could float in water because it is mostly made of gas.






 Uranus

  • Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It is surrounded by a set of 13 rings. It is an ice giant (instead of a gas giant). It has a thick atmosphere made of methane, hydrogen, and helium. It is the only planet that spins on its side. Uranus spins the opposite direction as Earth and most other planet




Neptune


Neptune orbits our Sun, a star, and is the eighth planet from the Sun at a distance of about 2.8 billion miles (4.5 billion kilometres). Neptune is the final planet in the Solar System. Neptune is more than 30 times as far from the Sun as Earth. A year on Neptune is equivalent to 164.81 Earth Years. Neptune is an 'Ice Giant' .Neptune has at least 5 rings

Forces

                                                                    Forces What is a force? A force is The push or pull on an object with mass causes it to change its velocity . Force is an external agent capable of changing a body's state of rest or motions It has a magnitude and a directions. They are measured in Newtons.     types of force .. . Gravitational force.-    a force of attraction (attractive force) that attracts all physical forms having mass Non-contact forces- they pull or push on objects without touching them Magnetic force.-  attraction or repulsion that arises between electrically charged particles because of their motion Nuclear force.-  a force that acts between the protons and neutrons of atoms . Frictional force.-  t he force that resists motion when the surface ...

State Of Matter

Image
                                                       State Of Matter What is the 3 state of matter? There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles. Solids ... Solids have a fixed shape and fixed volume, which means they don't move to fill a container when they're placed in it. They hold their own shape and volume. Solids cannot be compressed into a smaller space very easily. There's not much space between the  atoms. Most solids change their shape if they are squeezed or pulled with enough force . The particles in the solid cannot move closer together, but they can often slide around and past each other if they are pushed hard enough. Thin bars and sheets of solids can often be bent or moulded. Liquids ... The atoms in ...
