- Ecosystems
Scientists Say: Vector
Vectors are used to transfer things. Sometimes the transferred item is a disease, but scientists can also use vectors to insert helpful genes.
- Physics
Scientists Say: Frequency
The distance between one wave peak and another is wavelength. But how fast those peaks are moving along is frequency.
-
A paper microscope magnifies on the go
Classroom microscopes can be clunky and costly. An inventor has designed one so small, tough and cheap that it can go home in every kid’s backpack.
- Physics
Scientists Say: Yottawatt
On Earth, scientists measure energy use in watts. When you have lot of those watts — one million billion billion — you have a yottawatt.

Sewing circuits: A crafty way to get kids interested in STEM
Many classrooms teach electric circuits with batteries and wires. But with e-textiles, students can help design and light up their own art projects.
- Physics
Scientists Say: Wavelength
When something travels as a wave — such as light — scientists can measure it by its wavelength, the distances between the peaks.
- Physics
Scientists Say: Watt
Say Watt? This is a unit used to measure the flow of energy being used.
- Math
Scientists Say: Y-axis
The bars on a graph tell you nothing unless you know what they mean. The lines on the sides can let you know.
-
How you handle your smartphone could become a secure ID
The way you move is specific to you, and only you. A teen shows the way someone picks up a phone could be used as a ‘secure’ ID.
-
A teen uses math to pick out a voice in the crowd
One teen set out to improve the hearing aid his grandfather hated. His new mathematical model amplifies only what people most want to hear.
-
This teen designed a filter to save a stream
Shocked to find out how much phosphorus was in local streams, a teen invented a filter to remove it.
- Life
Scientists Say: Yeast
For some people, yeast bring to mind slimy infections. But these little fungal beasts are used to make bread rise, too.
