A free YouTube video and downloadable PDF file based on a substance called ambergris, produced by sperm whales and used in the making of perfumes. References to the use of ambergris during the Black Death, as part of the King of England’s breakfast, and use by the ancient Egyptians. A fun introductory topic to themes such as chemistry, World Oceans Day, environment, conservation, whales, oceans, and the seaside. But equally of use for lessons on history, geography, smoking, laws, synthetic chemicals, and smell as one of our senses.

A how to video on YouTube, and a free PDF download with instructions on how to make your own ocean slime. A fun activity for World Oceans Day, to run alongside an ocean theme, or as part of a science lesson about mixtures and compounds. The ingredients for the slime are basically water, liquid glue, liquid starch, glitter, and food colouring.

A free video and PDF poster based on the Alderney Lighthouse on the British Channel Islands. The lighthouse was built after a ship called the SS Liverpool wrecked in bad weather.

A resource I created for students who want to understand more about the world. A PDF file, that covers: - THE SCIENTIFIC EXPLANATION of why the sea is salty (references to Isaac Newton, Christopher Wren, King of England, and Edmond Halley’s ‘continental weathering’ theory. We then look at how the question was finally answered in 1979 during an expedition to the black smokers and hydrothermal vents on the Pacific Ocean floor). - THE FOLKLORE EXPLANATION of why the sea is salty (references to the Vikings, Norse Mythology, Grotti’s Song, the Orkney Islands of Scotland and North Atlantic Ocean, and the story of the ants and the friendly giant from the Philippines). - Suggestions for follow up activities The file could be broken into sections as a longer topic or workbook, or given as a stand alone project or introduction to a new topic. There are multiple elements that cross over for topics on Vikings, oceans, exploration, biology, geography, slavery, storytelling , folklore, cultural diversity, and as inspiration and scientists who overcame adversity. May be suitable for gifted younger learners, or for secondary school students, STEM clubs, or students with English as a foreign language.

How many oceans are there on planet Earth? There are five oceans in the world, from biggest to smallest they are: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern (Antarctic) Ocean, and the Arctic Ocean. The waters of the oceans mix together thanks to the movement of currents which create the World (global) ocean. About 71% of the planet’s surface is covered with our oceans. What is the difference between an ocean and a sea? An ocean is larger than the sea, and is not surrounded by land in the same way as a sea is, for example, the Baltic Sea or the Black Sea.
