I really like the idea of the classroom experiment of darkening the room to mimic a dark sky. My 6th class would really enjoy that!

Create an observing plan for autumn that shows which planets are visible in the evening sky.

I created a plan using timeanddate.com for September which will show which planets are visible in the evening sky.

On September 1st Mercury, Venus and Neptune will be slightly difficult to see. Mars and Uranus will have average visibility, Jupiter will have fairly good visibility and Saturn will have perfect visibility.

 

I will introduce this plan to my 6th class by introducing the solar system to them focusing on the planets we will be observing. I will engage them by creating a model of the solar system using clay/Styrofoam balls.

The pupils will then be split into groups and research a planet each and create a poster with interesting facts about each planet. We will then use the stellarium software to take a virtual sky tour. This will allow the pupils to have a chance to see what the sky will look like during their observation session.

For the observation night the location will be well chosen with the correct equipment. I will provide simple star maps showing the positions of the planets for the date. I will create a planet spotting checklist for the pupils to allow them to mark off the planets they spot and write any notes they have.

I hope that the above would really engage my pupils.

Construct a sundial in your immediate area or plan for your school grounds to see where a sundial could be placed

6th class

This lesson would generate great excitement in my classroom. There are so many teaching points in relation to sundials that it would integrate across a variety of subjects such as history, maths and geography.

I would begin by discussing the history of timekeeping and how ancient civilisations used sundials. Then I would explain the science behind sundials: the Earth’s rotation, the concept of shadows, and how they relate to time. I would show them images of different types of sundials and bring in one that I have at home.

We would discuss where would be the best location for the sundial. I would hope that they would select a large area in our school field which has no obstructions near it and has exposure to the sun. I would highlight the importance of finding true north using a compass for the sundial.

The pupils would then work in groups to discuss what materials we would need for the sundial. They need to be strong enough for the Irish weather. Once decided we would set to work constructing it and then positioning it. The pupils would mark the time at each hour using stones. It would be a great activity for the entire school to enjoy.
