Building a solar balloon is a fun and educational activity for anyone interested in science and engineering. It is a type of hot air balloon that uses the sun’s energy to heat the air inside the balloon, lower the air’s density, and causing it to rise.
Below is a list of common chemical names, their chemical formula, common name, storage code, mass and density, as well as notes on where to find the chemical (other than a chemical supply house). Use as a reference when conducting chemistry experiments, shopping for chemical supplies, and storing chemicals at home, or setting up your…
The only way to tell if paint contains dangerous lead is to test it. Here is a well-known oxidation-reduction reaction that can be used to test for the presence of lead.
In a darkened room, we will hold a red LED flashlight to our thumb. The thumb will glow bright red indicating much of the light passed right through our thumb. When we hold a green LED flashlight to our thumbs however, almost all of the light is absorbed.

It’s not difficult to set up a home chemistry lab. Below is everything you need to know about how to set up a home chemistry lab including a complete list of suggested equipment for your chemistry lab, chemicals for your lab and how to obtain them, and details on how to safely organize and store…
In this science experiment we will mix molecules to make a glitter globe (i.e. a “snow globe”). We will combine rubbing alcohol, vegetable oil, and a few other tiny, shiny things to make a cool science toy.
Making a terrarium, a self-sustainable ecosystem with a living, growing plant inside a sealed bottle, is a pretty easy project and the plant growing inside can survive for decades without any watering or other care. Here’s how you can build a terrarium, or garden in a bottle, on your own.
Science Fair judges can be pretty weird. If you could get into their head and figure out how they think, you’d have the upper hand in the contest – right? Well since we can’t get into their heads (you don’t have a medical degree yet so don’t even think about it), we’ll do the next…
