A sulky is a small, two-wheeled horse-drawn cart. It is used for driving or racing horses.
Sunburn is a type of burn that you get when you spend too much time in the sun without wearing sunscreen. Bad sunburn can be extremely painful, and can make your skin blister and peel. You treat sunburn the same way as any other minor burn, with special burn creams and even anaesthetic sprays. Too much exposure to the sun makes your skin age early and become dry and wrinkly, and can give you skin cancer.
Scientific name: genus: drosera
Sundews are a large family of carnivorous plants. They catch insects on sticky glands on their leaves and digest them. Sundews live in poor soils and need the nutrients from insects that they cannot get from the soil. They get their name because the sticky substance they produce looks like beads of dew.
Sundials are a device that uses the sun to tell the time. A sundial is made up of a horizontal dial plate with numbers on it, and a vertical upright called a gnomon. As the sun moves, the shadow cast by the gnomon moves around the dial plate, and you can read the time off what numbers it points to.
Some sundials use a shaft of light rather than a shadow, and the dial plate may be curved not flat. Some sundials have enough information on the dial plate to be able to tell the date as well as the time.
