Creating a 3D neurone ( or neuron ) model is a great way to learn about the central nervous system and how messages are transmitted around the body. 3D neurone models are also a fantastic addition to a school science fair project about the nervous system. What are neurones? Neurones ( often called nerve cells…
If you eat or drink too quickly, you might find you burp! Burping is how extra gas is expelled from the body. The gas is forced out of the stomach up the oesophagus and out of the mouth! These burping balloons are very easy to set up and great fun to watch. The balloons will…
Human teeth allow us to tear, grind, and crush food into smaller pieces, which we then swallow and digest for energy. Did you know the way your teeth are aligned in your mouth is unique to you? A bit like a fingerprint. Parts of a Tooth Enamel Enamel is the outer layer of the tooth…
Calcium is a mineral needed for strong bones and teeth. Calcium also plays a role in blood clotting, the normal functioning of the heart and is used by nerves and muscles to help us move. This activity using eggs is a very visual way to demonstrate what happens if you don’t have enough calcium in…
Do you think you have fast reactions? Have you ever measured your reaction time? Did you know you can test your reaction time using just a ruler? Reaction time is the time it takes for a person to respond to a stimulus. For example, if you touch something very cold, there is a slight delay…
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…
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….
You might have had an x-ray in hospital if you’ve hurt a bone or in the dentist when having a check up. X-rays are incredibly useful in medicine and have lots of other uses too. X-rays are used to view inside objects and materials. If you’ve been to an airport you’ve probably had your bag…
Olympic and sports day fever is about to start, so I’ve put together a collection of fun sport-themed science experiments and investigations. You can find out what happens to your heart rate and breathing as you exercise, make a model of a heart and lung, discover why balls bounce, test reaction time and lots more…
This collection of science experiments for learning about the human body is perfect for encouraging kids to learn about their bodies! I’ve split the ideas into three age groups: preschool, primary age ( 5-11 ) and secondary ( 12+) but these are very loose recommendations. Hopefully you’ll find something that sounds fun to try! I’ve…
