Have you ever seen someone flick a tablecloth out from under plates that stay in place? The plates stay in place because of a concept called inertia. A slightly easier way to demonstrate inertia is by dropping an Easter egg ( or other object ) into a container. We usually do this science demonstration with…
Butterflies play a vital role in the natural world and are crucial to healthy ecosystems. Caterpillars eat plant matter and are a food source for many animals. Butterflies are important for pollination and also an integral part of the food chain. Butterflies are known to be sensitive to environmental changes, and their population numbers are…
Have you ever wondered how far Jupiter is from Mars or Venus from Earth? Our handy calculator makes it easy to find out! All distances are average and approximate, as it’s difficult to be accurate with such large distances. Planets are also at different distances from each other depending on where they are in orbit…
You’ve probably seen or experienced most of these common science phenomena before, but you may not have thought about why they happen. From sticking a magnet onto your fridge to colourful lights in the sky, we explain ten fascinating phenomena and offer ideas for learning more about each one. Get ready to delve into the…
Einstein Rings are a type of gravitational lensing in which the light from a galaxy or star passes a large object, like another galaxy or black hole, and is bent around it. If the alignment is right, the light appears as a ring around the large object. The galaxy or black hole closest to the…
This activity uses Skittles to demonstrate radioactive decay. The rate of decay depends on the isotope of the element and is referred to as the half-life. Radioactive decay is a random process. To understand the concept of a half-life, we’re going to pretend Skittles are radioactive atoms. Skittles that land with the S upwards are…
The spring equinox marks the astronomical beginning of spring in the Northern Hemisphere. The balance of daylight shifts, marking the start of warmer, longer days. In the Southern Hemisphere, it marks the start of autumn. Equinox means equal night. At the spring equinox, the sun is directly above the equator, and day and night are…
I can’t believe it’s time for British Science Week again. It seems like two minutes since we planned our space-themed experiments last year. If, like me, time has run away from you and you need some easy ideas for British Science Week, we’ve got some suggestions that might help.
