Description
General aims
To understand what light is and what her components are.
To understand how energy from the sun makes conditions life on the Earth possible.
To understand how electromagnetic energy is present in our everyday life. It is also used when listening to the radio, watching TV, using a cell phone or a microwave oven. We all depend on this energy, without it there would not be any life on our planet and there would not be the world as we know it.

Time required to use the resource with the students
3h 1h presentation and analysis of the resource
2 h discussion and comparison of the results of the
experiment by Herschel
How to use it
After assigning the vision of this resource as a homework, the teacher introduces the concept of electromagnetic spectrum, wavelength and wavelength scale according to common objects. Then the teacher starts a guided discussion on commonly used technologies: mobile phone, radio, various remote controls, wireless controls. Following, through brainstorming, the teacher involves students in a discussion that aims to encourage ideas to solve the problems that have emerged. Then, the teacher divides the class into small groups that must analyze and study what has been learned and that, independently and not in the presence of the teacher, perform the Herschel experiment by following the instructions by the teacher. In this way, students learn practically how the scientist, by means of a glass prism, discovered the existence of infrared light. The results obtained allow students to verify the link between color and temperature. The teacher must not anticipate the result of the experiment because one of the objectives is exactly understanding and using the scientific method: observing a phenomenon, asking questions, formulating a hypothesis, carrying out experiments, drawing conclusions.
Possible difficulties for the students
Defining the concept of wave.
Illustrating the relationship between the wavelength of a radiation and its energy.
