When will the next naked-eye supernova event happen? What will it look like? Will we be safe? Astrum Answers!

How can scientists possibly know the age of the universe? Well, through a variety of factors, including redshift, the CMBR and more.

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

At high speeds, wheels may appear to be turning backwards, creating an optical illusion known as the Wagon wheel effect. This happens because our brains fill in gaps between images to create the illusion of continuous movement. As a...

Discover Gornergrat, a hotel, restaurant, and observatory offering stunning stargazing views and a rich history, perched high in the Swiss Alps with breathtaking views of the Milky Way.

Seven established researchers provide real-world examples of the relevance of TOK (Theory of Knowledge) concepts in their research. This interdisciplinary TOK Sampler explores the overlap between theory of knowledge and the...

The discovery by Robert Bunsen which allowed elements to be identified more easily, and even led to the discovery of new ones. Chemistry - Atoms And Bonding - Learning Points. Gustav Kirchoff assembled the first spectroscope - two...

We create a simple electromagnet by coiling wire around a nail and passing current through it. The magnetic field around the electromagnet creates similar patterns in iron fillings to a permanent magnet. Physics - Electricity And...

We use vinegar to remove the shells from eggs without breaking them. Two eggs are placed in a beaker of vinegar, but one is half coated with clear nail polish. The exposed shells dissolve over time and the eggs swell as more water moves...

We compare the properties of three iron mixtures: iron and water, iron and oil and a ferrofluid - a mixture of compounds containing iron and oil. First, we look at how iron filings behave when mixed with water and then oil. We then hold...

We use the enzyme pepsin and hydrochloric acid to simulate the conditions within the stomach in two boiling tubes. Cooked egg whites are ground and added to two boiling tubes of hydrochloric acid, but one is mixed with a crushed antacid...

We test the effects of smoking by drawing first air and then cigarette smoke through apparatus that contains mineral wool and universal indicator. The air has no effect, but the smoke discolours the wool and changes the colour of the...

We use two magnets and a set of scales to examine magnetic field and strength. One magnet is attached to the scales and a second is lowered towards it. When opposite poles are facing each other, the weight on the scales decreases as the...

We use a microscope to examine the blood flow in the open circulatory system of asellus aquaticus. We are able to see the haemolymph moving through its limbs in different directions. Biology - Human Body - Learning Points. Large...

This video explores cause and effect relationships of magnetism, as well as electric interactions. The program explains how students can conduct an activity that illustrates how magnets exhibit forces on specific types of matter, and...

Learn about Leonardo da Vinci, the artist and engineering genius of the Italian Renaissance who painted the Mona Lisa and sketched inventions ahead of his time.

By the end of this learning object, the student will be able to: Explain the concept of heat transfer by convection.43379

Surprisingly, despite the sun's heat, lakes don't visibly evaporate like a glass of water. There are two main reasons for this: first, the amount of water present in lakes and large water bodies is huge (at least compared to what you...

Jump into 'How Do You Observe A Hypothesis?' to see how scientists turn their ideas into experiments! A quick, exciting peek into scientific discovery, great for budding experimenters.

Mercury, the closest planet to the sun, poses challenges for observation and exploration. NASA's Messenger probe has provided valuable images and data. Messenger utilizes gravitational assistance from Venus and Earth to approach Mercury....
