- Brain
Let’s learn about touch
Most senses are concentrated around your head. But touch all over your body, and you need every inch.
- Agriculture
New technologies might help keep drought-prone farms green
After learning how much damage drought can do to crops, two teens designed ways to detect a thirsty plant and make sure it gets enough water.
- Environment
Local glacier could be gone in a decade, young scientist finds
A teen calculated the volume of a glacier by drilling into it with jets of steam — then used that to estimate how long before all its ice will be gone.
- Plants
Scientists Say: Pollen
Pollen is a mass of tiny reproductive cells. These grains combine with egg cells to form seeds — but on the way, they can make some people miserable.
- Computing
Will this smartphone app become your exercise coach?
When one teen couldn’t go to the gym, she invented an app to bring her gymnastics coach to her home. She succeeded and won a major award for it.
- Chemistry
Scientists Say: Metal
Metals are substances that can be elements, alloys or compounds. They all conduct heat and electricity and can be formed into different shapes.
- Life
Scientists Say: Genus
A genus is a group of closely related species. It’s the first part of the two-part system called binomial nomenclature, used to name living things.
- Life
Let’s learn about dogs
From learning the names of their toys to sniffing out viruses in human sweat, dogs are far more than household pets.
- Physics
Staying grounded in space requires artificial gravity
On TV, people in space walk around like they’re on Earth. How can science give real astronauts artificial gravity? Spin right round, baby.
- Chemistry
Scientists Say: Alkaline
Alkaline chemicals are basic — substances that produce hydroxide ions in solution.
- Chemistry
Level up your demonstration: Make it an experiment
What’s the difference between a demonstration and an experiment? Questions, measurements and many, many replications.
- Math
Scientists Say: Pi
Pi is the ratio of a circle’s circumference to its diameter. But some mathematicians say life would be easier if we used a different ratio instead.
