English Class fourth graders have been learning about light for the past few weeks. After making foldables about the properties of light and rainbow spectrum spinners, the pupils began to learn about the science of the light spectrum. They learned that light is defined by its wavelength and frequency and that light behaves something like waves. The visible spectrum is made up of light within a certain range and frequency. These are the colours that we see.
However some non-visible types of light waves are infrared rays, microwaves, radio waves and X-rays. These type of waves make up the electromagnetic spectrum and are greatly used in science and technology in our daily lives. The English Class fourth graders made an accordion foldable to record information about the electromagnetic spectrum under the guidance of their environmental studies teacher, Mr. Gregg.
