The article "Top 10 Heaviest Spacecraft Ever Launched" from BBC's Science Focus examines the most massive spacecraft to have flown in Earth's orbit and beyond.
In Einstein’s Year of Miracles, narrator Kate Yule discusses the four papers that Einstein wrote in 1905, a year that is known as the Year of Miracles. One of those papers was on the Theory of Special Relativity. Watch how tennis balls being ejected from a moving truck appear stationary from the ground, but appear to move when observed from the truck. This illustrates how moving objects can appear differently when viewed alongside other moving objects. Learn how this theory can be applied to light to redefine the notion of time. This video is excerpted from BBC’s Einstein & Hawking: Masters of Our Universe, a mind-bending documentary that tells the story of how the two most famous scientists of the 20th Century transformed our understanding of the Universe and changed the world.

Happy holidays! With so many celebrations all over the globe during this season, it's the perfect time to teach your Grade 3–5 students about winter holidays around the world. Make copies of this mini-book (simply print on both sides flipped on the short edge, stack, and fold to assemble) for your students and invite them to read about each holiday and complete a simple report page full of questions, coloring, drawing, favorite facts, and more. Here are the eight winter holidays covered:
-
Diwali: A Hindu Festival of Lights celebrating the victory of light over darkness, with lamps, fireworks, and family gatherings.
-
St. Lucia Day: A Scandinavian holiday honoring St. Lucia, featuring processions with candles and special buns to bring light during the dark winter.
-
Las Posadas: A Mexican tradition reenacting Mary and Joseph’s search for shelter, celebrated with processions, songs, and parties.
-
Hanukkah: A Jewish holiday celebrating the miracle of the Temple’s menorah oil lasting eight days, marked with candles, dreidel games, and fried foods.
-
Winter Solstice: The shortest day and longest night of the year, celebrated by many cultures as the return of the sun with feasts and light-themed traditions.
-
Christmas: A Christian holiday celebrating the birth of Jesus, often marked with gift-giving, decorations, and family gatherings.
-
Kwanzaa: A weeklong African American celebration honoring African heritage and the Seven Principles through candles, reflection, and community activities.
-
Lunar New Year: An Asian cultural holiday welcoming the new year on the lunar calendar, celebrated with family reunions, special foods, and traditions for good luck.
In Why Your Voice Sounds Different in the Shower, host Harith Iskander explains why singing in the shower often sounds better than you might think. This happens because bathrooms have special acoustics. The smooth, hard surfaces like tiles and mirrors reflect sound waves back to you, making your voice sound louder and clearer. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
In How Weedy Seadragons Reproduce, narrator Sir David Attenborough dives into the shallow waters of Australia to find the incredible weedy seadragon! With tiny fins that keep it steady against the current, the weedy seadragon is perfectly designed for its underwater world. In spring, males and females perform a graceful mating dance, mirroring each other's movements. But here's the twist: it’s the father who carries the eggs! This video is excerpted from BBC’s Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
