Tuesday 19 th May 2020 LO Exploring planet

Tuesday 19 th May 2020 LO: Exploring planet years. Write this in your book. You should be able to complete your work independently. If you have any questions, write them down and we can discuss them during our weekly phone call.

Think How long does it take the Earth to rotate once on its axis? Axis

It takes the Earth 24 hours or one day to rotate once on its axis. Well done if you remembered this from our last lesson! Axis

We have learnt that as well as spinning on its own axis, Earth also orbits the Sun. How long do you think it takes for the Earth to travel once around the Sun?

Can you remember the names of the other planets in our solar system? The mnemonic My Very Excited Mother Serves Us Noodles we learned last week might help.

Neptune Uranus Mars How many could you name? Venus Mercury Jupiter Saturn

This diagram shows how far each planet in our solar system is from the Sun in kilometres (km).

Do you think there is a relationship between the distance a planet is from the Sun and how long it takes to travel around it? Predict which planet you think takes the shortest time to orbit the Sun and which planet you think takes the longest time to orbit the sun. Write your predictions in your book. I predict _____ takes the shortest time to orbit the sun. I predict _____ takes the longest time to orbit the sun.

Use the internet to research the orbit time of each planet. You can record this in days, years or both. Record the data in a table like the one below. Try to find this information on your own but you can use this website if you get really stuck: https: //spaceplace. nasa. gov/years-on-other-planets/en/ Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Orbit time (in days) Orbit time (in years) 365. 26 1

Which planet has the shortest orbit time around the Sun and which planet has the longest orbit time around the Sun? Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Orbit time (in days) 87. 97 224. 70 365. 26 686. 98 4, 332. 82 10, 755. 70 30, 687. 15 60, 190. 03 Orbit time (in years) 0. 2 0. 6 1 1. 9 11. 9 29. 5 84 164. 8

Was your prediction correct? Mercury has the shortest orbit time around the Sun. Neptune has the longest orbit time around the Sun.

Draw a diagram showing the planets and their order from the Sun. As an extra challenge you could draw the orbit path of each planet and include the time it takes for each planet to travel once around the Sun from your table. 84 years

Well done Year 5! I hope you enjoyed learning more about the planets in our solar system.
