All the objects that we see in the world around us, are made of matter. Matter makes up the air we breathe, the ground we walk on, the food we eat and the animals and plants that live around us. Even our own human bodies are made of matter!
Different objects can be made of different types of materials (the matter from which objects are made). For example, a cupboard (an object) is made of wood, nails, hinges and knobs (the materials). In this tutorial, we explore the classification of matter and the properties of different materials.
The periodic table of the elements is a method of showing the chemical elements in a table with the elements arranged in order of increasing atomic number. Most of the work that was done to arrive at the periodic table that we know can be attributed to a Russian chemist named Dmitri Mendeleev. In this tutorial, we explore the arrangement of elements on the periodic table.
