Concrete is made from cement, gravel, lime, sand and water. It starts as a dry mix of all the powders, and after water is added it will go hard within a matter of hours from a chemical reaction.

Scientific name: vultur gryphus or gymnogyps californianus
Condors are a type of vulture found in the Andes and the Californian mountains. They are one of the largest birds in the world. They can live to 50 years old in the wild, and have a wingspan of up to 3 metres.
They spend a lot of their time soaring through the air looking for large dead animals to eat.
A cone is a shape with a round bottom that gets smaller as it goes until it reaches a point. If you cut a slice through a cone parallel to the bottom, it will be the same shape as the bottom. If you cut a slice through the cone vertically going through the top point, you will get a triangle.
Many things are cone shaped. volcanos tend to be cone-shaped, pinecones and pine trees like the ones in the picture are cone-shaped, and of course traffic cones are cone shaped.
