Science Sparks is full of easy and fun science experiments for kids to do at home. Our fun science investigations include engineering, coding, biology, chemistry and physics experiments.
Learn more about the wonderful world of science by trying our exciting science experiments, cool facts, free printables, photos and videos. We’ve also got a great collection of STEM projects, STEM Challenges and science fair projects.
Our science experiments include removing the shell from an egg, launching bottle rockets, create edible life cycles, making lava lamps and lots more science experiments for kids of all ages.
To answer this question, you first need to understand how sound travels on Earth. In very basic terms, sound travels from the source of the sound to our ears by vibrating air molecules. Sound waves need a medium to travel through. Space is a mostly empty vacuum, so there’s no medium for sounds to travel…
This week, the U.S. government issued its first ever fine to a company for leaving space junk in space. Why is space debris a problem? Space is a pretty big place. The problem is that even a tiny piece of space junk left behind can cause massive damage if it collides with a spacecraft or…
Alloys are made by adding another element to a metal. Creating alloys allows scientists to combine the properties of different metals. If a heavy, strong metal is mixed with a light, weak metal in the correct amounts, the result is a light, strong metal. For example, pure iron is very malleable (its shape can be…
Helicopter seeds are a type of seed that spin as they fall from a tree. The spinning movement and the fact that they are light and can catch the wind allows them to travel further from the parent tree than if they just dropped to the floor. This is one method of seed dispersal used…
The pH scale measures how acidic or alkaline a solution is. It ranges between 0 and 14. Acids have a pH of less than 7. Alkalis ( or bases ) have a pH of over 7. pH 7 is neutral. How is pH measured? pH is measured using an indicator. An indicator is a dye…
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…
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…
