How a Bridge Stands Up
A bridge has to hold its own weight and the weight of everything crossing it. The simplest bridge is a beam: a flat piece laid across a gap. A beam bridge cannot be very long, or it sags in the middle. An arch bridge is curved. The curve pushes the weight out to the ends, where the ground is solid. That is why arch bridges can cross wider gaps.

From Flower to Jar
A honeybee visits about a hundred flowers on one trip. She sucks up nectar and stores it in a special stomach. Back at the hive, she passes the nectar to another bee. That bee chews it for about half an hour. Then it goes into a wax cell. The bees fan the cell with their wings. The water dries out and the nectar thickens into honey. Then the cell is sealed with wax.
- 1. What do the bees use to seal the cell?
- 2. Where does the bee store the nectar on the way home?
