World Environment Day!
World Environment Day is marked each year on 5th June. It is a global reminder of the importance of protecting our planet. This year’s theme focuses on restoring land and building resilience against drought – issues that are deeply connected to life on Earth.
Why not use this as a chance to explore what makes our planet so special, and how conditions here compare to those elsewhere in the Universe? Our activities can help you dig deeper into these questions:
- Hot, Cold, or Just Right? – Compare different planets to Earth and explore what conditions make a world habitable.
- Investigate How the Sun Supports Life – Discover how sunlight helps plants make food and produce oxygen.
- Life on Earth – Explore the unique combination of elements that support life here.
- What Does Life Need? – Learn about the key ingredients for life and consider whether we might find them elsewhere.
Eid Al-Adha Mubarak!
To all those celebrating, we wish you a joyful and peaceful Eid al-Adha, which begins this year on the evening of 6th June and lasts until the 10th June.
Did you know that astronomy plays an important role in marking Islamic festivals like Eid?
The Islamic calendar is a lunar calendar, which means months begin with the sighting of the new crescent Moon. Skilled observers look to the evening sky for the first glimpse of the Moon to confirm the start of a new month, blending ancient tradition with modern astronomy.
This is a wonderful opportunity to talk to your students about how different cultures use the skies to guide timekeeping, celebrations, and daily life.
World Oceans Day
Each year on 8th June, World Oceans Day reminds us of the vital role oceans play in supporting life on Earth. Oceans help regulate our climate, provide food and oxygen, and are deeply connected to the Moon through the phenomenon of tides.
Why not dive into this theme with your students and explore the link between astronomy and the sea?
- Why Does Earth Have Tides? – Discover how the gravitational pull of the Moon and Sun creates tides on Earth through an interactive simulation.
- Explore Tides – Build a model to explore the gravitational effects of the Moon and Sun on Earth's tides. Learn about different types of tides.
- Investigate Tides – Use predicted tidal data to explore how tides change over time. Analyse the graph to spot patterns and make predictions.
The June Solstice
The June Solstice falls on 21st June and marks the longest day of the year in the Northern Hemisphere, bringing the start of summer. Meanwhile, in the Southern Hemisphere, it is the shortest day and the beginning of winter. This is a perfect time to explore how Earth's tilt and orbit create the seasons and change the way we experience daylight and shadows.
Discover our top Things To Do resources to help your learners understand the science behind this seasonal event:
- Why Does Earth Have Seasons? – Watch this short animation to discover how Earth's tilt causes the seasons.
- Why Do We Have Seasons? – Use this interactive animation to explore how sunlight changes across the globe.
- Explore Day and Night Around the World – Investigate how Earth's rotation creates day and night in different places.
- Why Do Shadows Change Over Time? – Learn how the position of the Sun in the sky changes the shape and length of shadows.
Women in Engineering Day
23rd June is Women in Engineering Day, a chance to spotlight the amazing women shaping our world through creativity, innovation, and science.
Explore the journeys of some of our inspiring career heroes:
- Mary Jackson – NASA’s first Black female engineer, who also supported young people in STEM through community science clubs.
- Mimi Aung – An engineer behind the first Mars helicopter flight, named one of the BBC’s top 100 women in 2019.
Don't miss our famous activity, Design a Telescope? –– Discover what engineers and astronomers must consider when building new telescopes.
International Asteroid Day
On 30th June, we turn our eyes to space for International Asteroid Day — a global event to raise awareness about asteroids and the role they play in our Solar System. These space rocks hold clues to the formation of our Solar System and can even pose a risk to life on Earth.
Explore our asteroid-themed activities:
- What are Asteroids and Comets? – Learn about these rocky visitors from space and how they formed.
- What are the Risks from Asteroids? – Discover how likely it is that an asteroid could impact Earth and what scientists are doing to prepare.
- Hunt for Asteroids – Use real telescope images to search for moving objects in space!
- Make Your Own Asteroid Impact – A hands-on experiment to explore what happens when asteroids hit planetary surfaces.
Celebrating Pride Month!
June is Pride Month, a time to celebrate the contributions, courage, and visibility of LGBTQ+ individuals across all fields — including science, astronomy, and engineering.
Let us shine a light on just a few of the inspiring LGBTQ+ scientists who have shaped our understanding of the Universe:
- Jan Eldridge – Astrophysicist and passionate advocate for diversity and inclusion in science.
- Alan Turing – Groundbreaking mathematician and codebreaker, whose ideas laid the foundation for modern computing.
- Lisa Harvey-Smith – Astrophysicist and author, championing gender equity in STEM.
- Nergis Mavalvala – Physicist whose work was crucial in detecting gravitational waves.
- Sally Ride – The first American woman in space and a powerful advocate for science education and LGBTQ+ representation.
Their achievements remind us that science is for everyone — and that diversity fuels discovery!
