Red cabbage indicator is a simple way to tell whether a substance is an acid or alkali. Acids can be found in the food we eat, in our bodies and around the home. Some acids, especially those found in cleaning products, can be very harmful, so take care when using them and always read their…
Did you know blood makes up around 7% of the weight of a human body? The average adult has 5 litres of blood flowing around their body in a massive network of arteries and veins transporting oxygen and nutrients to cells. Blood also removes waste, contains cells that fight infection and helps with temperature regulation….
A gene is a length of DNA which codes for a single characteristics or trait we inherit from our parents. Genes control every aspect of our body and how it works. Each characteristic has its own gene. Genes play a large role in how you look and everything else that makes you the person you…
Magic opening flowers are a brilliant, super simple science investigation using just paper and water. The folded paper flowers open up as the paper absorbs the water. They are a great way to learn about capillary action and transport of water in plants too. You can make these as simple or creative as you like….
Did you know that honey bees dance to share information with the rest of their colony? Bees use different types of dances to let other bees know where to find nectar ( their food source ). What is a waggle dance? Bees dance in a figure of eight and wag their tail in the middle…
Our changing climate and loss of bee friendly habitats are not good news for bees or the planet. Some species are already extinct, and many more are on the threatened list, but why are bees so important? Why do we need bees? Bees pollinate flowers Bees pollinate 75-80% of food crops worldwide. Without bees to…
Following my weather-themed science experiments, I have a collection of wind science experiments to share today! Learn about renewable and non-renewable energy. Make an anemometer to measure wind speed, a wind vane to work out which way the wind is blowing, pinwheel, storm in a jar and lots more! What is wind? The wind is…
The Beaufort Scale was named after Sir Francis Beaufort ( a hydrographer with the Royal Navy ) and lists the effects of increasing wind speeds. The scale was initially designed to show the effects of the wind on a battleship at sea. When is a hurricane warning issued? Hurricane warnings are issued when winds reach…
Wind turbines use energy from wind to generate electricity. Each turbine has a generator inside. When the blades rotate they turn the generator which produces electricity. This is a form of non renewable energy, it doesn’t get used up and doesn’t produce harmful polluting gases. You’ll need A square of paper – about 15cm x…
At Science Sparks, we love autumn with its crunchy leaves, beautiful colours, and crisp, fresh air! I’ve compiled a huge collection of autumn science experiments that you might like, and I’ve also pulled together these autumn STEM challenges to help you make the most of the changing seasons. If you’re looking for more general science experiments, try my collection…
