We made these virus models to show how different viruses have very different structures. They are also different sizes ( our models are not to scale ) and infect different types of hosts. At a very basic level each virus consists of genetic information in the form of either DNA or RNA surrounded by a…
A virus is a very tiny organism that can only live and reproduce inside another living cell. The cell the virus invades is called the host cell. The virus basically turns the cell into a factory to make more viruses which then invade more cells. Viruses consist of a stand of genetic information ( DNA…
The lungs are an essential organ for all mammals. Lungs have several features which make them perfect for exchanging gases. Today, we’re going to find out how lungs work by making a lung model. The lungs are part of our breathing system, which has two functions: Under the lungs is the diaphragm, a muscular sheet separating…
Do you know how much sugar is in kid’s drinks? We set up an investigation to find out how the amount of sugar differs between common drinks. We decided to calculate the amount of sugar in the full bottle or container rather than for the same amount of the drink as most people would drink…
The heart is a muscle that functions as a very powerful pump to transport blood around the body. It beats between 60 and 100 times a minute but can beat even faster than that if needed. The blood transports nutrients and oxygen to cells in the body, and waste products are removed. The right side…
Stethoscopes are used to listen to a person’s heart and breathing. You can make a very basic stethoscope easily using just a cardboard tube, tape and a funnel. This is a brilliant science activity for younger children as part of a doctor role play activity. How to make a stethoscope What you need: Kitchen roll…
