The human body is pretty amazing! We have skin to help protect us from pathogens and pollutants, a skeleton to allow us to move and protect vital organs and a digestive system that can break down food, keeping the good bits and expelling the waste! These fun human body facts are a great starting point…
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…
Today’s STEM challenge is to design and build a bumper car that will rebound back after a collision with a wall or another mini vehicle. This car themed STEM challenge is a great hands-on introduction to Newton’s Laws of Motion and a fun engineering and design project too. Bumper Car STEM Challenge You’ll need Balloons…
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…
The Grinch is one of my favourite children’s Christmas books. This melting the Grinch’s heart activity is super simple and can be carried out in lots of different ways. Younger children can just try to rescue the buttons by pouring warm water over the ice, while older children could set it up like a real…
