What will students learn  Students will learn that sedimentary rocks are formed from layers of sediment, which can contain fossils; that igneous rocks are formed from cooled magma, with minerals arranged in crystals; that metamorphic rocks are formed from existing rocks exposed to heat and pressure over a long time; the three rock layers inside earth are the crust, the mantle and the core; sedimentary, igneous and metamorphic rocks can be inter converted through the rock cycle; that weathering is the weathering down of rock by physical, chemical or biological processes; explore the differences between minerals (which have chemical formulae) and rocks (which are mixtures of minerals, so cannot have a formula); identify  the causes of weathering and erosion and describe how they occur; construct a labelled diagram to identify the processes of the rock cycle; suggest how ceramics might be similar to some types of rock; know that erosion is the movement of rock by water, ice or wind (transportation); know that an orbit is a path taken by a satellite, planet or star moving around a larger body. Earth completes one orbit of the sun a year; predict patterns in day length, the suns intensity or an object's shadow a different latitudes; explain why places on Earth experience different daylight hours and amounts of sunlight during the year; know that the solar system consists of planets rotating on tilted axes while orbiting the sun, moons orbiting planets and sunlight spreading out and being reflected; know that stars are bodies which give out light  and which may have a solar system of planets; know that our solar system is a tiny part of a galaxy, one of many billions in the Universe; know that a galaxy is a collection of stars together by gravity. Our galaxy is called the Milky way; know that an exoplanet is a planet that orbits a star outside our solar system; describe how space exploration and observations of stars are affected by the scale of the universe; explain the choice of particular units for measuring distances; make deductions from observation data of planets, stars and galaxies; describe the appearance of planets or moons from diagrams showing their position in relation to the earth and sun.
Key Knowledge that students should know at the end of 'Topic' This is the knowledge that students will meet for the first time in this topic  The three different types of rocks and how each one is formed. Know that sedimentary rocks may contain fossils. Know that the Earth has three rock layers inside which are called the crust, the mantle and the core. Students should know that rocks can be converted through the rock cycle and should be able to label a diagram explaining this. Students should know what ceramics are and how they might be similar to some types of rock. Also know how weathering and erosion occur. Weathering is the wearing down of rocks by physical, chemical or biological processes and erosion is the movement of rock by water, ice or wind. They will also know how to predict patterns in day length, the suns intensity or an objects shadow ar different latitudes. Know that an orbit is a path taken by a satellite, planet or a star orbiting around a larger body. And the Earth complete one orbit of the sun every year. Know that the sunlight hours change during the year and why. That stars give out light. Know that our galaxy is called the Milky Way galaxy and there are billions of galaxies in the Universe. Units for measuring distances in space. Also will know the appearance of planets or moons from diagrams showing their position in accordance to the earth and sun
This is knowledge that students may have met before but will need to deepen their understanding  Students should have basic knowledge on the movement of Earth and the planets in the solar system. They should also be able to describe the movement of the Moon in accordance to the Earth. Should know the Sun, Earth and Moon are spherical bodies.  And also the Earth rotating would explain day and night. In terms of rocks, students should know the different types of rocks and how fossils may be formed and trapped in a rock.
Key Skills that students should be able to demonstrate at the end of 'Topic' This is the skills  that students will meet for the first time in this topic Using new measuring units for measuring distances in space. Being able to extract information from tables and fill in a table.
This is skills that students may have met before but will need to develop  Using measuring distances for space. Being able to label the rock cycle diagram. Be able to draw planets or moons from diagrams to show their position in accordance to the Sun and and Earth.
Key vocabulary that students should know and understand

sedimentary rocks, metamorphic rocks, igneous rocks, fossils, rocks, minerals, salt, strata, weathering, erosion, rock cycle, orbit, star and ecliptic

The Big Question  What is the Earth made  from and why do we have have day and night, seasons and different weather?
