How do bees make honey?

Tap to reveal the answer

science

Bees make honey by collecting nectar from flowers, storing it in their special honey stomach, and then passing it between bees to break down the complex sugars into simpler ones. They finally deposit the processed nectar into honeycomb cells and fan it with their wings until most of the water evaporates, creating honey.

Why do we have leap years?

Tap to reveal the answer

science

We have leap years because Earth takes about 365.25 days to orbit the sun, not exactly 365 days. By adding an extra day every 4 years, we keep our calendar aligned with Earth's position in its orbit around the sun.

Why does Earth have seasons?

Tap to reveal the answer

science

Earth has seasons because its axis is tilted at about 23.5 degrees as it orbits the sun, causing different parts of Earth to receive more or less direct sunlight at different times of year. This tilt, not Earth's distance from the sun, is what creates summer, fall, winter, and spring.
