Thanks for the recommendations! I had never heard of johnwalsh, but will definitely give him a look now !
I like the idea of bringing the lesson towards school change. Having light monitors in school can better spread the awareness that is needed, and raises the chances of them bringing the knowledge home.
A KWL chart is a great way to start these kind of lessons. The children would then be more surprised as a result of potentially how little they know about the topic, and would better highlight the need for awareness.
The Stellarium with Junior Infants sounds like a brilliant idea, I can imagine their excitement. It seems to be a great tool, and would wow the children!
I have to agree with Jamie and Rachel, the idea of the year long activity will maintain a general interest in the topic without keeping it the main focus. It better highlights the effects as well.
Consider how many Songs / Poems /Art can you think of to connect us with the Night Sky?
The Starry Night – Vincent van Gogh
Twinkle, Twinkle, Little Star
The Stolen Child by W.B. Yeats
The Skylight by Seamus Heaney
Moonlight Sonata by Beethoven
Clair de Lune by Claude Debussy
The Owl and the Pussy-cat – Edward Lear
Northern Lights by Philip Pullman
Star of the County Down!I would begin a lesson with the students by introducing biodiversity and what it means in our local area, including parks, gardens, and hedgerows. I would take the students outside to observe and record different plants, insects, and birds using a simple checklist. I would then guide them to compare findings and discuss how human activity affects these habitats. I would introduce light pollution by showing how streetlights and buildings change night environments. I would ask students to consider how artificial light impacts nocturnal animals, feeding patterns, and plant growth. I would encourage group discussion and hypothesis building about changes they notice. I would finish the lesson with students suggesting ways to reduce light pollution locally, such as better lighting design and turning off unnecessary lights, helping them connect science learning to real world environmental responsibility. I would also reflect on learning outcomes with students together at the end session.
I would begin with a short comparison between the night sky in Meath, where I work and a darker-sky location such as Sligo., where I am from .Students examine two sets of images and quickly note differences in star visibility and sky brightness. The focus is on identifying light pollution as the cause of reduced visibility in urban areas.
I would then get the students to discuss what they personally observe when looking at the night sky from home and compare this with the rural example. The teacher briefly introduces the idea that artificial lighting affects what we can see above us.
The main activity would be an investigation where students identify where their family members are from and research or gather descriptions of the night sky in those areas. They compare this with Dublin/Meath and record differences in a simple table.
The lesson ends with students sharing one key difference they found and suggesting one possible way to reduce light pollution locally.
I’d introduce the idea that the night sky changes with the seasons and that autumn gives us a different view of the planets than summer or winter. I’d start by asking students what they think they might be able to see in the sky after sunset and whether they’ve ever noticed a bright “star” that was actually a planet.
Using a simple autumn sky map, we’d identify which planets are expected to be visible in the evening sky and talk about why they’re visible at that time of year. We’d discuss how planets don’t make their own light, how they orbit the Sun, and why their positions in our sky change throughout the year.
Students would then work in small groups to create an Autumn Evening Sky Guide. Each group would choose one visible planet and create a small fact sheet.
Once everyone has shared their planet, we’d combine the fact sheets into a class display that students could use as a guide for observing at home.
As an optional homework activity, I’d encourage students to spend 10–15 minutes outside after sunset with a family member and see if they can spot one of the planets from our class guide. They could record the date and time, draw what they saw, and write a few sentences about whether they were able to find it and what they noticed. We’d use these observations in the next lesson to compare results and discuss why some students may have seen different things depending on the weather, time, or where they were observing.
To engage my students in this activity, I would begin with a class discussion about gravity and ask questions such as, “Why do we stay on the ground?” and “Would you weigh the same on every planet?” This would allow students to share their ideas and make predictions before the investigation.
I would then get the students to work in small groups to assemble an Earth tube and one planet tube (such as the Moon or Jupiter). Each tube would be decorated to represent its planet using colours, pictures, and interesting facts about the planet’s environment and gravity. This creative task would encourage teamwork while reinforcing science concepts.
Next, students would compare the two tubes and discuss how gravity differs between Earth and their chosen planet. Using the provided worksheet, students would calculate how much they would weigh on different celestial bodies and explain why their weight changes while their mass stays the same. They would also complete the lifting activity to experience how weaker gravity, such as on the Moon, would make objects feel lighter.
To conclude the lesson, each group would present their planet tube to the class, explaining how gravity affects weight on their chosen planet. Students would discuss on what they learned by writing a short paragraph.
