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…
A variable is a factor in an experiment that can be changed. When you set up an experiment in the correct way you need to think about control, independent and dependent variables. What is an independent variable? The independent variable is the factor changed in an experiment. There is usually only one independent variable as…
Fossils are the preserved remains of animals and plants that lived a long time ago. Fossils can also be evidence of a prehistoric animal or plant, such as footprints or evidence of nests or burrows. These are called trace fossils. Not all remains become fossilised. Fossilisation is actually quite rare. Most animal and plant remains…
Single use plastics are plastic items that are designed to be used just once. Things like food packaging, straws and water bottles are all single use items. Around half the plastic thrown away is single use, although hopefully, this percentage is dropping as the use of reusable drinking bottles and straws becomes more common Did…
Choose a question to investigate with the Science Sparks Squad. Each week we’ll add a new science question and associated activity to help you find the answer! This idea is that you print off a question you’re interested in and then try the activity to find the answer! Each science experiment or investigation is designed…
The Earth is located in a planetary system we call the solar system located in one of the four spiral arms of the Milky Way galaxy. Our solar system consists of 4 inner planets ( Mercury, Venus, Earth and Mars ) and 4 giant planets (Jupiter, Saturn, Uranus and Neptune ). There are also several…
Shadows are formed when light hits an object it cannot travel through. When you see your shadow on a sunny day, your body has blocked light from the sun. Light travels in a straight line. It cannot bend around your body, so you see a shadow. Shadows change shape during the day as the sun’s…
Are viruses alive is a tricky question that has caused a some debate over the years. The general view is that viruses are not alive. They don’t respire, convert nutrients into energy or excrete waste products like organisms we class as being alive do. Viruses can’t even reproduce without taking over another living cell. Once…
The Avogadro Constant is used to find the number of particles in a substance. What is the Avogadro Constant? The Avogadro Constant is 6.02 x 1023 What is a mole? One mole of a substance is the amount of the substance that contains 6.02 x 1023 particles. The particles measured can be atoms, molecules, electrons…
From the outside a raw egg and a hard boiled egg look the same, so how can you tell the difference? How can you tell if an egg is raw or hard boiled? The key is in the spin! A hard boiled egg will spin nicely and a raw egg will wobble. The raw egg…
