You can achieve a certain out of focus effect for the background, using it as subject isolation. Do note that 'bokeh' is a quality term for the out of focus area. It can be pleasing or not, but you cannot specifically achieve bokeh.
For background blur try to use the long end of your lens (vulgo: zoom to maximum), have the object close to you and the background far behind. This will show you that your kit lens is well able to achieve subject isolation.
