First Activity Working in teams based on last weeks homework each group share with the class the information that they researched have on the planets. The groups have 5 minutes to collate their information . Then each group presents to the class no more than 3 minutes each and everyone fill in the data in the space booklet Planet Description Atmosphere Surface Temp (oC) Size Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune

Activity 2 Kepler was a famous astronomer . When he investigated the motion of planets he made an important discovery based on hundreds of observation of the motion of planets

Mercury 0.241 0.39 Venus 0.615 0.72 Earth 1 Mars 1.88 1.52 Jupiter Here is data of the solar system. Copy this table out Plot two graphs A The time it takes for a year (period) on the Y axis against the distance ( on the X axis Then calculate the period squared and also the distance cubed and plot a new graph. Two have already been done What do you notice ? Planet Time for year Average Distance (AU) Period 2 Distance 3 Mercury 0.241 0.39 Venus 0.615 0.72 0.378 Earth 1 Mars 1.88 1.52 Jupiter 11.8 5.2 141 Saturn 29.5 9.54 Uranus 84 19.18 Neptune 165 30.06 Pluto 248 39.44

The Solar System… a quick quiz What planet are we on? Which planet(s) are between us and the sun? Which is the smallest planet? Which is the largest planet? Which planets have moons? Which planets have rings? Where is the asteroid belt? What is the nearest star to Earth? Learning Objectives By the end of this lesson you should… Be able to recall and recognise the relative positions of the Earth, Sun and planets Be able to recall the relative nature and sizes of planets, stars, comets, meteors, galaxies and black holes Be able to state the components of the known Universe Be able to explain the term ‘light year’

Where would it be on your scale?
