Today’s experiment is taken from a rather brilliant book from QED Publishing. Cracking Chemistry is part of the ‘Science Crackers’ range. It is beautifully laid out with striking photos and pictures to really catch a child’s attention and interest. My 4-year-old was fascinated. The book explains all about the world of atoms and materials. Each…
This is a special device you can make that makes eerie sounds like a creaking door or creaking steps! Perfect if you’re having a Halloween party or sleepover and want to spook your friends. You could simulate a haunted house! You will need the following: A plastic cup A paperclip Some wool Blue tack Water…
It’s Autumn here in the UK and the leaves are beginning to fall and go crisp under your feet. The trees are a variety of colours and there are seeds galore. It is the perfect time to get out and about and collect things like acorns, conkers, leaves, twigs, and feathers. Which is exactly what…
Did you know the inside of your nose is filled with goblet cells which create mucus, and very tiny hairs called cilia? The bigger hairs help stop unwanted particles from getting into your nose. Everything you smell gives off molecules which are very light and float in the air. When these get into your nose,…
This experiment looks at how egg white ( albumen ) is transformed as it is whisked. Egg white is about 2/3 of the total weight of an egg and is 10% protein, the rest being mostly water. To demonstrate the change in the egg white, we will find out how to make meringue! How to make…
Zoob Junior is a versatile modelling system which has brightly coloured plastic pieces that snap, click and pop together in many different ways. Modelled on the nucleotides that make up DNA, the movement of the Zoob mirrors the natural mobility of people, animals and machines. We were sent the 30-piece set to review, this comes…
Welcome to the first of a series of weather science related investigations. Rain gauges are easy to make and a simple first science activity for learning about the weather. My children love to check and record the rainfall each day, which has also helped my 2-year-old learn to recognise numbers. How to make a rain…
This is a lovely activity to demonstrate convection. Younger children will love it just for the moving snake, and it’s a great way for older children to start to understand what convection means. This activity requires a source of heat, so adult supervision is essential. You will need Paper snakeCotton thread TapeScissorsColouring pencilsA heat source…
Welcome to a very eggy week on Science Sparks! Shrinking eggs is the first of 3 egg based experiments, so if you like this one, pop back later in the week to see what else we have been up to! This experiment looks at osmosis. Osmosis is the net movement of water molecules across a…
This week we are making an Avocado Pit. It’s going to take a few weeks so bear with us. My 4-year-old thought he could plant a stick, and if he watered it, it would turn into a tree, so I thought this would introduce him to the concept of a root. How to grow an…
