Physical Changes:
1. Breaking a stick of chocolate in half.
2. Melting some ice.
Chemical Changes:
1. Combustion (the burning of something e.g. unleaded fuel)
2. Photosynthesis (producing glucose and oxygen from carbon dioxide, water and sun light).
These are some I thought from the top of my head, a bit mundane but they will do the trick.

What two examples is the physical change and chemical change of milk?
An example of a physical change in milk is when you freeze it, changing its state from liquid to solid without altering its chemical composition. A chemical change in milk occurs when it sours, involving the breakdown of lactose by bacteria to form lactic acid, altering its chemical composition.

CHEMICAL CHANGE: Such change is a permanent change and substances go through such changes not only alter their outer shape but also change their composition. For example: conversion of milk into yoghurt is a chemical change PHYSICAL CHANGE: Such change is a temporary change and substances go through such changes alter their shape and volume only but composition remains same. For example: water changes into ice and ice melt to water is a physical change.
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.

Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
