Matter is anything that occupies space and has mass. Everything around us is made of matter. You may have heard the phrase states of matter. Matter can take different forms depending on the conditions. Here on Earth matter is generally in the form of a solid, liquid or a gas. Matter is made up of…
Batteries are used to power toys, torches and other items that need energy to work. Batteries store energy as chemical energy which is converted into electrical energy when the battery is part of a circuit. When a battery is placed inside a circuit it pushes charge around the circuit. This pushing force is called voltage….
Voltage is the force that pushes current around a circuit. Imagine a battery being like a pump, pushing the current around the circuit. A more complicated way of defining it is that voltage is the difference in electrical energy between two points on a circuit. You can buy batteries with different voltages or use multiple…
Next time you boil up some red cabbage, make sure you save the liquid as it can be used for lots of easy science experiments. This red cabbage breath test is a fun twist on the more traditional testing the pH of different substances, although why not do both? Did you know you can even…
Isotopes are different forms of the same element. Isotopes of an element have the same number of protons and electrons but a different number of neutrons. This means they have the same atomic number ( number of protons ) but a different mass number ( number of protons and neutrons ). Paper Plate Isotope Models…
An element is a substance that cannot be broken down into another substance. Each element is made up of its own type of atom! The periodic table lists elements in order of atomic number and is laid out so elements with similar chemical properties form columns ( groups ). Atomic number is the number of…
Everything is made of atoms. Atoms are really, really small and are actually made up of even smaller particles called electrons, protons and neutrons. Atoms are not all the same. They have different numbers of electrons, protons and neutrons. Each different kind of atom makes up an element. An atom consists of a positively charged…
How do we see things? We see things because of light! The simple explanation Light bounces off objects and enters our eyes allowing us to see them. It’s harder to see at night as there’s less light to bounce off objects. Let’s make it a bit more complex Light enters the eye through the cornea…
Friction is one of my favourite science concepts to learn about! It’s easy to investigate in many different ways with fun hands-on experiments and investigations. Friction is created when objects are pulled past each other. Imagine pushing a box of books along a carpet and a wooden floor. It would be much easier to push…
The electromagnetic spectrum is the name for the different forms of light that are given off by objects in the Universe. Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays are all types of light, but with different energies! The different types of light have different wavelengths. What is wavelength? Wavelength…
