Once a plant has made seeds ( remember pollination and fertilisation? ) they need to be dispersed. Seed dispersal is the scattering of seeds. If seeds just dropped next to the parent plant, they would be competing for nutrients and light, so it’s better if seeds are spread out, allowing them to grow with less…
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….
A gene is a length of DNA which codes for a single characteristics or trait we inherit from our parents. Genes control every aspect of our body and how it works. Each characteristic has its own gene. Genes play a large role in how you look and everything else that makes you the person you…
Magic opening flowers are a brilliant, super simple science investigation using just paper and water. The folded paper flowers open up as the paper absorbs the water. They are a great way to learn about capillary action and transport of water in plants too. You can make these as simple or creative as you like….
Did you know that honey bees dance to share information with the rest of their colony? Bees use different types of dances to let other bees know where to find nectar ( their food source ). What is a waggle dance? Bees dance in a figure of eight and wag their tail in the middle…
Our changing climate and loss of bee friendly habitats are not good news for bees or the planet. Some species are already extinct, and many more are on the threatened list, but why are bees so important? Why do we need bees? Bees pollinate flowers Bees pollinate 75-80% of food crops worldwide. Without bees to…
Imagine pulling a delicious cake out of an oven. The smell slowly spreads around the room and then through the house. This is diffusion! The lovely cake smelling particles move from where there are lots of them ( high concentration ) to where there are less of them ( low concentration ). Diffusion can be…
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 digestive system is made up of several organs working together to make an organ system ( digestive system ). This activity shows how to make an easy digestion system model using food and tights! This activity can also be found in my book Gross Science! What is Digestion? Digestion is the process by which…
