Space – The Planets 05 July 2018 Starter: Match the definitions of the thinking, the braking and stopping distance. Then underline the key words in each definition The thinking distance is…. The braking distance is…. The stopping distance is…. the total distance the car travels from when the driver sees a need to stop to when the car actually stops. the distance the car travels whilst the driver is reacting and putting their foot on the brake pedal. the distance the car travels from when the driver puts their foot on the brake to when the car actually stops.

Space – The Planets 05 July 2018 What is good and what is wrong about these definitions? The thinking distance is the distance the car travels whilst the driver is focussing on the danger in the road. The thinking distance is the speed it takes the driver to put their foot on the brake The braking distance is the time between when the driver see the child step in the road and when they stop. The stopping distance is the time taken from when seeing a need to stop to actually stopping. The braking distance is the time the car takes to stop from when the brakes are applied to when it actually stops.

Space – The Planets 05 July 2018 Today we are learning about the Planets By the end of the lesson we will have been successful when we: Have used our understanding of key words in the explanation of thinking and braking distance Learnt about the order of the planets in the solar system and used our knowledge of their position and characteristics to explain some of their physical data.

Planet data Planets can be classed different ways…

Position

Composition ROCKY PLANETS (Mercury - Venus - Earth - Mars - Pluto) The rocky planets are mostly made up of rock and metal. These planets are very heavy and move slowly. They also do not have rings and very few moons. GAS PLANETS (Jupiter - Saturn - Uranus - Neptune) The gas planets are mostly made up of gases (hydrogen and helium). These planets are light for their sizes (just like a big air balloon) and move quickly. They have rings and lots of moons.

Size SMALL PLANETS (Mercury - Venus - Earth - Mars - Pluto) The small planets have diameters less than 13000 km across. Mercury and Pluto are sometimes referred to as lesser planets because they are so tiny. GIANT PLANETS (Jupiter - Saturn - Uranus - Neptune) The giant planets have diameters greater than 48000 km. The giant planets are sometimes also referred to as gas giants.

Which planets can we see from the Earth? What do you think effects if we can see a Planet from the earth? The size of a planet How far away it is The planets surface Mercury, Venus, Mars, Jupiter and Saturn

Questions Please answer the following questions in FULL sentences in your book In your books write down A-K and say what they are. What makes up what can be found at F? Which planets have rings? Which planet has a longer day than its year? Even though planet B is closer to the Sun, C is hotter, can you explain why?

You have won a free holiday to a planet of you choice. Find out about the planet you will visit using Planetary Data from the lesson as well as any information you can find on the internet or in books.   Produce a postcard on the attached card, draw a picture and write about your planet. You might want to consider the following in addition to other things: How long did it take you to get there What temperature it is? What is the planet made of? How often do you get a birthday if you were born on this planet? How big is the planet? What might the gravity be like on that planet (the bigger the mass of the planet te greater the gravity) What would it be like trying to walk on this planet?
