Written by Ammonites were sea creatures that lived before and at the same time as dinosaurs. They were a bit like a modern-day squid or octopus with a shell. Ammonite fossils have been found all over the world. The fossils resemble a curled-up snake, and for a while, people thought they were remains of snakes, earning them […]
Atoms are tiny particles of matter which make up everything in the universe. Everything you see is made up of atoms. Scientists spent many years trying to understand the structure of the atom, with several models and theories being disproved or improved upon along the way. Today we know that atoms consist of a nucleus […]

Use your smartphone for science Make a smartphone speaker Imagine you’re in the park having a picnic and fancy playing some music. What can […]
The Periodic Table is a table of all the elements we know about today. Elements are placed in order of atomic number ( number of protons in the nucleus ). The periodic table is a way of listing and organising elements. The rows of the periodic table are called periods, and the columns are known […]
It’s time to head off on another adventure Around the World in 50 Experiments. Today we’re off to Israel. Israel is a small country in the Middle East on the eastern shores of the Mediterranean.

If you take a look outside, you’ll probably see lots of green. Green grass, green leaves covering trees and green plants, but why are leaves green? Most plant leaves are green as they contain a pigment called chlorophyll which is green. Chlorophyll is needed for plants to absorb sunlight which they need to make glucose […]
The Earth started to form around 4.6 billion years ago! It’s thought that a star far away in space exploded, causing huge amounts of interstellar dust to collapse in on itself. Our Sun formed first, and then the rest of the planets. The Earth formed from rock and dust being pulled together. The heat from […]
Bridges and buildings need to be made from strong materials and cleverly constructed too. Some shapes make more robust structures than others. These simple investigations are all great for learning about strong shapes and stable structures in a fun and hands-on way. A structure is a building made from several different parts. Stable structure and […]
This very simple STEM challenge is a great way to find out why arches are such an important structural shape. Bridges often have arches to make them stronger and more stable. The arch shape allows any load on the bridge to be spread outwards along the curve of the arch. Pont du Gard is a […]
