Most spiders have eight eyes. Some species have less, but they always have an even number! Despite having so many eyes, the majority of spiders still can’t see very well and rely on their sense of touch and smell to navigate around their environment.

The idea behind this worksheet is that children take it outside, listen to the sounds around them and tick the things they can hear. There are three worksheets to choose from: things I can hear at the beach, in the forest and a general one. How do we hear noise? The simple explanation Sounds are…
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…

Here at Science Sparks, we love making science spooky! We’ve got fizzy witchy potions, creepy chia seed slime, a spooky noise maker, a…
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…
