Science Sparks is full of easy and fun science experiments for kids to do at home. Our fun science investigations include engineering, coding, biology, chemistry and physics experiments.
Learn more about the wonderful world of science by trying our exciting science experiments, cool facts, free printables, photos and videos. We’ve also got a great collection of STEM projects, STEM Challenges and science fair projects.
Our science experiments include removing the shell from an egg, launching bottle rockets, create edible life cycles, making lava lamps and lots more science experiments for kids of all ages.
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…
Hopefully you’ve already seen my ever growing collection of FREE science experiment printable instruction sheets. These cover experiments suitable for kids of all ages and are themed to many different topics including seasons and holidays. Launching today are several science experiment templates that can be used for writing up experiments and investigations and a STEM…
All moving objects have momentum. Another way to think about momentum is how hard it is to stop a moving object. It’s harder to stop an object moving quickly than an object moving slowly. What is the momentum equation? All moving objects have momentum. Momentum is a vector quantity which means it has size AND…
Pathogens are organisms that cause disease. Viruses, bacteria, protists and fungi are all pathogens. Pathogens cause communicable diseases. Diseases can be communicable or non-communicable. What is a communicable disease? Communicable diseases spread between people. Non-communicable diseases cannot be spread between people. An example of a non-communicable disease is heart disease. Examples of viral diseases Ebola…
Static electricity is the thing that sometimes gives you a little shock when you touch a metal door handle after walking on a carpet. It makes your hair stand on end when you put a woolly jumper on and can be used for lots of fun science experiments and demonstrations. This static electricity demonstration shows…
We’ve heard a lot about viruses recently, but how do they work? Viruses cannot live for long without a host. Viruses consist of either a DNA or RNA genome ( genetic code ) and a protein coat, some also have an extra fatty envelope to protect their genetic material. They cannot reproduce without being inside…
Have you ever had an electrostatic shock from a shopping trolley or escalator or noticed your hair standing on end when you rub a balloon on it? The shock is caused by static ( non-moving ) electricity, which is caused by electrons building up with no circuit to flow along. An object that has gained…
Chain reactions are a great, fun STEM project that always keeps my kids busy for hours. This Christmas themed version can be adapted in lots of different ways using whatever you have handy around the house. Books can be used as dominoes, baubles as balls, and bells to make noise. A chain reaction is a…
Is taste linked to smell? Have you ever wondered why food doesn’t taste as good when you have a cold and blocked nose? When you eat, smell chemicals from the food travel up your nose, where they are detected by tiny nerve endings at the back of the nose. These nerves send a message to…
Find out what pollution is, why it’s harmful, and how we can reduce it with these simple but effective science activities to teach kids about pollution.
