Where does rain come from? Most rain comes from the sea! Water on land, in lakes and seawater evaporates when it’s heated by the sun to form a gas called water vapour. Water vapour rises and cools back into water droplets forming clouds. When the droplets of water are big enough they fall as rain…
If you’re thinking of trying a science activity at home for the first time, or are a more seasoned kitchen scientist, red cabbage indicator is perfect! The humble red cabbage is great for making colour changing potions, testing the pH of different things around the kitchen and generally a great introduction to science at home,…
The kitchen is a great place to try some science! Kitchen chemistry experiments are some of the easiest and most fascinating activities you can try at home. They also use products you probably already have and sometimes you can even eat the result! Kitchen Chemistry Experiments Chill with Salt Use the ice and salt to…
Chemistry is the study of matter. Matter is basically anything that occupies space and has mass! We use chemistry everyday and everywhere. When you bake a cake the ingredients are chosen, measured and then cooked so they react together to create something tasty (or not, depending on how you combine ingredients and cook them )….
Several years ago, we started creating Easter egg hunts with codes as clues to make searching for the eggs take a bit longer. The codes started out very simple ( letters replaced with numbers ) but have become increasingly complex over the years. I’ve created some free printable easter egg codes to make this year’s…
An acid is a substance with a PH of less than 7. The pH scale measures how acidic or alkaline a substance is. A neutral substance such as pure water has a pH of 7! Acids form H+ ions in water. The higher the concentration of H+ ions, the more acidic the solution is. Examples…
This mini wave machine is a great way to demonstrate the concept of a wave! It’s easy to make, looks great and can be used over and over again! If you enjoy this activity, don’t forget to take a look at my other easy physics experiments. What is a wave? When you imagine a wave,…
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…
