Experiment: Making music with bottles
In this study, we investigate how the volume of air inside a bottle affects the pitch of the musical notes it can create.

Experiment: Why does the moon look larger on the horizon?
In this experiment, let’s investigate Emmert’s law, which may explain the full moon optical illusion.
- Plants
Flowers may electrically detect bees buzzing nearby
The discovery may reveal how plants time nectar production and share information with neighboring blooms.

Here’s how to build an internet on Mars
Future Red Planet residents will need to get online to talk to each other and Earth. But that will require a lot of new tech.
- Physics
Let’s learn about particles that help us peer inside objects
Particles such as muons, X-rays and neutrons help scientists peer inside fossils, mummies, pyramids, volcanoes and the human body.

Here’s why blueberries aren’t blue — but appear to be
Blueberries actually have dark red pigments — no blue ones — in their skin. Tiny structures in the fruits’ waxy coat are what make them seem blue.
- Oceans
Analyze This: Climate change may worsen the spread of ocean noise
Some parts of the ocean may become five times as loud in the future.

The weird sky glow called STEVE is really confusing scientists
Researchers are trying to figure out the recipe of atmospheric conditions that creates this aurora-like light show.

Scientists Say: Polarized light
Sunlight, lamplight and other lights are usually unpolarized. But passing light waves through filters can ‘polarize’ them.
