Over the years technology has grown in leaps in bounds
The new materials and technology developed over the years has pushed our advancement forward

The technologies we have today were not created perfectly on the first try
The majority of the technologies have been improved due to years of trying out different methods
For Example;◦ Pop Can openers
Trial – and - Error

Many of the devices we use today are only possible because of an improvement in some area of science.
Electricity was the biggest advancement
Without it we would not be able to run the vast majority of our equipment to perform tasks

As scientists and engineers and others learned more about electricity and other technologies many new and creative ideas emerged.
Eg. Microscopes and bullet trains

Initially robots were ideas of myth and science fiction.
Nowadays robots make the majority of our products such as cars, and appliances

Since the 1960’s recycling technologies have been created and improved upon to make our planet a better place◦ Biodegradable plastics
Newer technologies can help protect the environment from damage such as the robotic Oil Skimmers to clean up water spills
