Baking soda and baking powder can be easily confused. They have a similar function and name but work differently. Both are used to add air to mixtures, usually bread dough and cake mix. They are leaveners. The key difference is baking soda ( sometimes known as bicarbonate of soda ) needs an acid to work,…
The scientific method is the system most scientists follow when setting up an investigation. It has evolved over time, and many scientists have contributed to this way of working scientifically. What is the Scientific Method? There are several steps to the scientific method. Create a Hypothesis A hypothesis is a potential explanation for something a…
Almost everything to do with food and cooking involves science. Food is kept in a fridge to slow down the growth of microorganisms, some foods are preserved in vinegar others are kept in the dark. Bitterness in food and drink can be reduced by adding salt. Need to ripen a banana fast, no problem, pop…
You might have already seen our exploding seed pods and flying seed helicopters for learning about different types of seed dispersal. This activity teaches children about sticky seed pods. The challenge is to make a container for a seed that sticks ( temporarily ) to clothing. One way plants disperse their seeds is by using…
Most penguins live in and around Antarctica in the southern hemisphere. This means they have to be able to survive in extreme cold conditions. Penguins have several adaptations that allow them to stay warm when temperatures plummet. This simple science investigation uses a wax crayon to show how a waxy coating acts as a water-repellent….
If you’re a teacher or a parent searching for educational resources, it can be easy to get overwhelmed by the sheer amount of information on the internet. While it’s great that there’s so much help out there, not all resources are accurate, good quality or aligned with the UK National Curriculum. This is where the…
To celebrate Roald Dahl Day on the 13th of September, I’ve put together a fun collection of Roald Dahl science experiments and activity ideas. My 8-year-old is currently devouring Roald Dahl books, and I remember spending many happy hours reading them as a child, so this collection has been great fun to put together and…
This simple science demonstration is a fantastic way to learn about volcanoes, tectonic plates and convection currents. Volcanoes are mostly found on tectonic plate boundaries because the movement of tectonic plates allows magma to reach the surface. The Ring of Fire around the Pacific Plate is home to around 75% of the world’s volcanoes! Volcanoes…
Hot air balloons work thanks to convection currents. The heat source under the balloon heats the air inside. A convection current inside the balloon keeps the air warm as heated air continually rises, cools and falls to be heated again. The warm air inside the balloon is less dense than the cooler air on the…
If you’re looking for a fun science experiment to do in the kitchen, you’ve landed in the right place! These five easy milk science experiments use milk as the main ingredient. Make ice cream with milk, ice and salt. Find out how to make butter from cream ( not quite milk ), make glue from…
