- Physics
Scientists Say: Acceleration
Acceleration is a change in velocity. That could mean a change in speed or in direction.
- Physics
Scientists Say: Radiation
Radiation is the motion of energy through space as waves or particles.
- Physics
Let’s learn about light
Light is a form of energy that moves in waves. Some light comes in waves we can see. Other waves are invisible to us — but still affect our world.
- Brain
Scientists Say: Neuron
Neurons are the foundational cells in the nervous system. They pass along and process information using electrical signals.
- Science & Society
When COVID-19 comes for your science fair
When labs shut down due to COVID-19, teens took their science fair projects to the internet and … sometimes even to the bathroom.
- Life
Scientists Say: Hominid
Scientists are still working out what counts as a hominid. Some say it’s just people and our extinct ancestors. Others say add more apes.
- Space
Let’s learn about the moon
The moon is Earth’s nearest neighbor, and its gravity helps stabilize the planet’s climate and creates the tides.
- Life
Scientists Say: Egg and sperm
An egg or a sperm cell contains half of the normal genes an organism needs. They fuse together to form a new individual.
- Climate
Scientists Say: Weather
The state of the atmosphere in a specific place and time is weather. Over a long time, the weather conditions in an area will reveal its climate.
- Chemistry
Let’s learn about acids and bases
Acids give away particles with positive charge. Bases accept positively charged particles. They are both critical for chemical reactions.
- Space
Scientists Say: Planet
Planets have to orbit a star, be big enough to form a sphere and keep other objects out of their path around their star.
- Math
Scientists Say: Outlier
Data points often fall within a normal range. When one data point sticks out a lot, it might be an outlier.
