This presentation explores the use of 360° videos as an immersive, pedagogically structured tool to support pre-service teachers in planning and enacting laboratory-based science activities. A 360° video was developed around an ocean acidification experiment to model fair testing, capturing the full laboratory process. The setting for this project was a science laboratory room that is equipped for physics, chemistry, biology, and environmental science instruction in a teacher education program at a Canadian university. The 360° video allows pre-service teachers to experience the lab procedure, enhancing procedural competence and instructional readiness before conducting experiments with their future students. This pilot also demonstrates the potential for 360° videos to support student science laboratory preparedness, laboratory safety awareness, science learning motivation, and engagement. Future research will examine pre-service teachers’ experiences using the video as a pre-laboratory intervention and extend its use to in-service teacher professional development. This study highlights 360° videos as a scalable, immersive strategy to strengthen teacher preparation and enhance experiential hands-on science learning.

Share the knowledge on the ocean
The ocean is the foundation of life on Earth. But its health is at grave risk as ecosystems and habitats approach or surpass critical tipping points. In the search for solutions, ocean science is indispensable. The third World Ocean Assessment offers the most comprehensive evaluation to date, providing Governments, institutions and the public with the evidence needed to shape coordinated, effective action.
Five years ago, the previous Assessment found persistent degradation of marine ecosystems. This third Assessment documents a deepening crisis, as climate change, pollution, overfishing and biodiversity loss put ocean systems under severe strain. Its findings demand urgent action, through stronger multilateral cooperation, greater ambition and decisions grounded in the best available science.
This Assessment comes midway through the United Nations Decade of Ocean Science for Sustainable Development and the United Nations Decade on Ecosystem Restoration. It takes stock of what we have learned, how far we have come and what more is needed to secure a healthy, resilient ocean for current and future generations.
The entry into force of the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction in January 2026 marks a historic milestone for ocean stewardship and multilateral cooperation. Now we must translate that momentum, and the latest science, into decisive action for a healthy and resilient ocean.
May this Assessment strengthen our resolve to protect the ocean and, in doing so, help safeguard our climate, our food systems, our prosperity and our future.
António Guterres, Secretary-General of the United Nations

Today, the U.S. Global Change Research Program (USGCRP) released the third edition of the nation’s climate literacy guide: Climate Literacy: Essential Principles for Understanding and Addressing Climate Change. The guide presents information that is important for individuals and communities to know and understand about Earth’s climate, the impacts of climate change and solutions. A team of federal scientists, communicators, educators and program leaders worked collaboratively to update the guide.
“The climate literacy guide is a major investment in education and workforce development that will help build America’s climate-ready workforce and communities,” said U.S. Secretary of Commerce Gina Raimondo. “The rising threats of climate change are accelerating, and we need a new generation of climate-literate and specially skilled workers who can help communities address a wide range of climate impacts – from sea level rise, flooding, and water quality issues – so that we can tackle the climate crisis.”
“The climate literacy guide is a rich educational resource drawing from the latest scientific consensus on a broad spectrum of topics in climate science,” said NOAA Administrator Richard Spinrad, Ph.D. “It will help bring climate literacy to every community in America and around the world.”
…
This resource arrives as the U.S. suffers more frequent, intense, climate-driven extreme events that impact public health, the economy and historical and cultural resources. This summer was Earth’s warmest on record, with August global temperatures extending the streak of record-high monthly global temperatures to 15 successive months.
“The updated guide is a useful entry point for anyone who wants to understand why climate change is happening, how it affects us and our communities and what we can do about it,” said Jane Lubchenco, Ph.D., Deputy Director for Climate and Environment, White House Office of Science and Technology Policy.
While the first edition of the guide provided a physical and natural science definition of climate literacy tailored for all forms of education, this new edition expands this standard to embrace physical science as well as local and Indigenous Knowledge, social sciences, climate solutions and climate justice. The skills and knowledge in this guide can help everyone build resilience to climate change.
According to the guide, a climate-literate person:
- Understands the essential principles of Earth’s climate system and the options to address human-caused climate change. (These principles and options are summarized in the guide).
- Recognizes credible information about climate change and knows where to find it.
- Communicates about climate change in accurate and effective ways.
- Is able to make informed decisions related to climate change.
Research in the journal Ambiooffsite link shows a climate-literate society is better able to develop and implement climate solutions that benefit all. Incorporating scientific concepts as well as Indigenous and local knowledge in communication and education can improve climate literacy and make climate actions more effective.
…
The climate literacy guide was first published in 2008 by the USGCRP and updated in 2009. This third edition of the guide is built on the latest climate assessments: The United States’ Fifth National Climate Assessment (November 2023) and the Intergovernmental Panel on Climate Change Sixth Assessment Reportoffsite link (2021-2023).
The guide is available in interactive web and downloadable PDF formats that will connect with learners from all walks of life. It contains photos, artwork and other compelling visuals to facilitate learning.
To access the guide, visit USGCRP or Climate.gov.

Why are our oceans turning acidic?
See why our oceans are turning acidic due to climate change.
This is an experiment which is hard to do at home and is best suited to laboratory conditions, where appropriate safety measures can be put in place. If you do not have the correct setting and equipment, we have produced a video of the experiment which you can find below.
Equipment
- 2l graduated cylinder
- 2ml potassium hydroxide (1M) or sodium hydroxide (1M)
- 1l water
- 25ml universal indicator
- ~10g dry ice
Method
- Pour the water into the cylinder.
- Add the potassium hydroxide(KOH) or sodium hydroxide. (NaOH) to the cylinder to make a dilute base.
- Add 25ml of universal indicator to the cylinder. You should see the liquid turn blue/purple to reflect the basic pH. You will need to give the solution a stir.
- Now gently add the dry ice into the cylinder. You should see gas bubbles rising through the solution, vapour at the top and the solution change colour to an orange/red colour.
So, what is happening here?
Dry ice is solid CO2.
As the dry ice is dropped in the liquid, it sublimates, going from a solid directly to a gas. This gas bubbles through the liquid, and the vapours you can see at the top.
The CO2 reacts with the water in the solution producing hydrogen, H+, ions.
CO2 (g) + H20(l) → H2CO3 (aq) + 2H+(aq) + CO3 (aq)
The H+ ions produced, react with the hydroxide, OH–, ions in the base, producing water and acting to neutralise the solution.
H+(aq) + OH–(aq) → H2O(l)
However the universal indicator in solution ends up yellow, indicating the solution is a weak acid. This is because eventually there are no OH– ions left, and instead unreacted H+ remain in the solution, turning it acidic.
Optional extra: while the dry ice is still bubbling, you can add more potassium hydroxide or sodium hydroxide to the top of the cylinder, one pipette-full at a time. You should see the liquid temporarily returning to its purple colour, but then changing to yellow again as the carbon dioxide bubbles through.
So how does this relate to climate change?

In this episode, the host discusses the significance of utilizing alternative modes of transportation, such as walking, cycling, or public transport, to decrease carbon emissions from cars. The host emphasizes that these alternative transportation methods not only benefit the environment but also promote personal health.
While the host acknowledges that electric vehicles (EVs) are a viable option for transportation since they don’t consume fossil fuels and therefore don’t contribute to carbon emissions, they also encourage the use of walking, cycling, or public transport. These options are not only environmentally friendly but also promote physical activity and overall well-being.
Furthermore, the host highlights the concept of reducing food miles as a means to minimize transportation-related carbon emissions. They suggest consuming locally grown foods and eating locally, as most meals in the US travel over 1,500 miles to reach consumers. By purchasing and consuming local and seasonal food, individuals can reduce the energy and CO2 emissions associated with food transportation.
Overall, the episode emphasizes the importance of utilizing alternative modes of transportation, such as walking, cycling, or public transport, to reduce carbon emissions from cars. It also promotes the idea of eating locally and consuming locally grown foods to minimize transportation-related carbon emissions.
In this episode, the host emphasizes the significance of eating locally grown foods as a way to reduce the transportation of food and the associated carbon emissions. The host explains that most meals in the US travel over 1,500 miles to reach our plates, and this transportation by road, rail, or air consumes energy and releases CO2, with air freight being the most polluting. By choosing to eat locally, such as shopping at farmer’s markets or local groceries, individuals can significantly reduce the distance that food needs to travel.
